"So-and-so movies are really good-looking, definitely more than the box office of hundreds of millions now!"

Surfing the internet, you can brush such messages from time to time.

Especially in this year’s Spring Festival, audiences have raised similar box office arguments in Deep Sea, Unknown and even Wandering Earth 2. Whether it’s fans’ grievances, capital control or even the film’s self-disclosure, it also shows that the final result does not match the quality of the film itself.

Although there has always been a phenomenon in the film market that a certain film is "not a blockbuster" or "popcorn movies are in power",However, judging from this year’s Spring Festival movies, the phenomenon of different box office and word of mouth is particularly impressive.

Take "Man Jiang Hong", the box office champion of the Spring Festival, as an example. During the period, it gained nearly 2.8 billion yuan, but the discussion surrounding the film flooded the network. According to the public opinion statistics of the whole network from the media, the negative accounts for nearly 40%.

China Ping-Pong’s Jedi Counter-Strike, which was delayed for many times and received good response, was previously scheduled for the National Day last year, and this time it was scheduled for the first day of the New Year’s Day, and then it was postponed to the third day of the New Year’s Day. But unfortunately, even after the file change, the box office is still not improving.

On the third day of the New Year’s Eve, "China Table Tennis Jedi Counterattack" accounted for 10.2%, but the box office was only 2.6%; On the day of the premiere, the box office failed, and the cinemas also adjusted and lowered the film’s schedule the next day, and the box office went down all the way.

In the end, the film had no choice but to announce the withdrawal from the Spring Festival file and change the Spring Festival to a small-scale screening, and change the battle to February 17.

In the statement issued on January 25, the film also clearly admitted: "Due to the serious mistakes and shortcomings of the publicity and distribution team in decision-making, preparation and promotion, the film fell into a particularly passive situation in the Spring Festival file."

It can be said that the success or failure of the film is determined by many factors, such as the announcement team, the choice of schedule, the audience’s reaction, the innovation of the film theme and so on.

0one

Schedule is the primary consideration.

For this year’s major films, the choice of schedule is particularly important.

Due to the backlog of many films last year, it is bound to be released in all major schedules this year. The number of slots is limited and the number of films released is increasing. The competition pressure at the box office and film arrangement is bound to become more intense. During this year’s Spring Festival, Deep Sea and China Ping-Pong’s Jedi Counter-Strike have staged "tragedies" that caused the box office to fail because of improper schedule selection.

Many examples seem to have proved:It is better to "set the file early" than "set it skillfully".

The "Deep Sea" with an investment of 200 million yuan can only be returned to the book in the Spring Festival file; "I really hate long-distance relationships" with an investment cost of only 20 million yuan can also sell well in May 1st, winning nearly 200 million box office.

For the film, the importance of choosing the timing of the release is self-evident.

Image source: Cat’s Eye Professional Edition

Judging from the many films that have been scheduled in the first half of the year, compared with last year, many films were crowded into the popular schedule, and this year’s Chinese film schedule is no longer superstitious and deliberately pursues the popular schedule. For example, February, as the traditional "introduction month" and off-season, ushered in a large number of films such as Panther 2, Ant Man 3, China Table Tennis Jedi Counter-attack, Broken Net, When the Wind Comes Back, and so on, and all of them were released on Fridays in February and March.

The number of films released is increasing, and the competition for arranging films is fierce. The film release should be both "timed" and "measured"; For these films, choosing to be released in the off-season and avoiding weaknesses also avoids the fate of being released in major schedules and being "cannon fodder" for a big fight between immortals.

02

The key to the decision-making of publicity and development

On the other hand, this year’s film team’s announcement and decision-making means have a key impact on the box office.

This year’s Spring Festival is a great success for commercial films. In terms of how to stimulate the audience to watch movies, the head film has achieved the ultimate.

On the eve of the release, "Man Jiang Hong" won the first wave of family fun by focusing on "suspense+comedy".

In the later stage of the film’s release, the publicity team frequently appeared on the hot search list of Weibo topics because of "mistakes" in posters and fonts. The eyes of netizens who are good at discovering loopholes are naturally sharp, but it cannot be ruled out that the film announcement team will take the "black and red" route and attract people’s attention.

At the same time, "Exchange of Life", which is just a comedy theme for the Spring Festival file, has a poor box office because of the diversion of its core audience and the unfavorable publicity of the film.

Wandering Earth 2, which takes the box office "stamina" route, is also not to be outdone, and many topics such as # Crowdfunding around #, # Film Details # and # Film Cost # are listed on Weibo Hot Search. As more details behind the film were gradually revealed, it also aroused the curiosity of the audience when they walked into the cinema.

Launching various forms of publicity, marketing and topic manufacturing through multiple platforms on the network will attract more attention and test the wisdom and innovation ability of the publicity team, which will naturally affect the final market performance.

0three

The mobile movie market and audience taste are more important.

In addition, the audience’s viewing habits and tastes have a significant impact on the box office.

Take the two animated films "Deep Sea" and "Bear with Me" in the Spring Festival as an example. As of February 7, the box office of "Bear with Me" exceeded 1.27 billion, nearly twice the box office of "Deep Sea" of 682 million.

Image source: Cat’s Eye Professional Edition

In addition to being greatly influenced by the schedule, the reason why the two films have such a wide box office gap is essentially that the two films have a gap in grasping the core audience.

The story of Deep Sea is self-contained. Although the art picture is excellent, considering the atmosphere of family reunion during the Spring Festival, the heavy story tone makes it unattractive to the parent-child audience, which is the main force of the Spring Festival animated film, resulting in poor box office.

While "Bear Haunted with Me" Bear Heart "firmly grasped the just-needed parent-child viewing demand during the schedule, the theme of maternal love’s film was more in line with the schedule atmosphere, and the unique track of" Zi Gong Xiang "also created favorable conditions for the further fermentation of film reputation, and finally ended up with the third place in the schedule.

In this regard, director Tian Xiaopeng also voluntarily admitted that there were scheduling and investment mistakes in the live broadcast of Tik Tok, indicating that the film investment was too large due to the deep obsession with creation; Moreover, the film’s expression is too artistic, lacks commercial considerations, and does not take into account the audience’s feelings, which leads to the film’s defeat in the "left and right attack" of the Spring Festival file.

In addition, "Man Jiang Hong" replaced "Exchange of Life" as the lever of the "comedy movie" in the Spring Festival, which also proved that:With "suspense+comedy" and "sci-fi+comedy" and other films, a single comedy film has become increasingly unable to meet the diverse viewing needs of the audience.

However, with the change of time, the wind direction of the film market has also changed for all to see.

A major trend reflected by the national film market after the Spring Festival is:The proportion of family-style movies has been reduced, and movie fans, friends’ parties and couples’ movies have gradually become the mainstream.

Under such a background, dramas with certain movie-watching threshold, individuality and unsatisfactory initial box office will usher in the "second spring".

Wandering Earth 2′ s national roadshow, which started on the fifth day of the Lunar New Year’s Eve, is aimed at grasping the strategy of the working party returning to the first and second lines after the holiday and taking the "long-term" box office. Up to now, the daily box office of Wandering Earth 2 has surpassed that of Manjianghong, and major media predict that the final box office of the film will exceed 3.9 billion.

There is no doubt that the box office of movies can be said to be more unpredictable under the influence of multiple factors:Schedule selection and audience’s aesthetic preference all affect the final box office performance of the film in real time.

Excellent quality, pleasing announcement, and the release opportunity that caters to the audience’s taste … These factors have produced different chemical reactions to the box office in different periods. It also proves that:There is no single fixed process and so-called experience from the announcement to the market, which requires more imagination and innovation.

For the cinemas in the middle and lower reaches, it is necessary to realize the changing logic behind the key factors that affect the box office of films and actively allocate resources such as activity planning, film arrangement adjustment, marketing and publicity for film audiences.

The picture shows that workers are processing mugwort in a mugwort processing poverty alleviation workshop in Tongbai County. source map

　　A common "weed" has turned into a "golden grass" to get rid of poverty and become rich, in the hometown of medical saints — — Nanyang, Henan, is nothing new. This very common "wild grass" growing all over the mountains is called wormwood.

　　According to statistics, the planting area of wormwood in Nanyang City exceeds 240,000 mu, and four wormwood industrial parks have been built, with 1,529 registered enterprises and annual sales of 8 billion yuan. It has become the largest wormwood processing base and wormwood leaf distribution center in China, with a national market share of 70%. It has driven more than 100,000 farmers to benefit from planting, harvesting, processing and sales, including more than 31,000 poor people. The whole wormwood industry has shown a vigorous vitality and has become one of the excellent projects for poverty alleviation and development in local rural areas.

　　Wormwood turns into a "golden leaf"

　　In the eyes of many agricultural technicians and growers, wormwood with its own green ecological "attribute" is the "best partner" to develop poverty alleviation industries. The planting area of wormwood is large and farmers are enthusiastic about planting. To this end, Nanyang City has also established the Ai Industry Association and introduced measures to encourage the development of the Ai industry. According to the principles of farmers’ voluntariness, interest linkage and mutual benefit, all localities have guided the establishment of professional cooperatives and cooperative associations of Ai Cao to cultivate large-scale Ai Cao growers, and "Ai Nong" has embarked on the road to prosperity because of the "Ai Xiang".

　　"The national wormwood looks at Wanai, and Wanai is best counted as Tongbai." Yin Zhehua, a poor household in Xiongzhai Village, Maoji Town, Tongbai County, talked about wormwood. Yin Zhehua not only planted wormwood, but also used his spare time to work in a nearby wormwood processing factory. It can be said that it was with "Ai" wealth that he ran towards a well-off society. "My husband died early, and there are two children at home. In the past few years, the days have been tight, and it is common to go to the construction site to do heavy work. Since I built the wormwood precision poverty alleviation employment base at my doorstep, I no longer go to the construction site to work. Now I grow wormwood myself and go to the factory to process moxa sticks. My work is much easier and I earn a lot of money in one month. " Yin Zhehua said happily.

　　Nanyang is rich in traditional Chinese medicine culture. In Zhang Zhongjing’s Treatise on Febrile Diseases, there are 6 prescriptions using wormwood, and in Synopsis of the Golden Chamber, there are more than 20 prescriptions using wormwood. Every Dragon Boat Festival, sachets fluttering in the streets and lanes are living advertisements of wormwood products. With the improvement of people’s living standards, the demand for health is more and more urgent. As a pure natural product, wormwood is favored, and wormwood industry has become the most distinctive sunrise industry and the most dynamic industry to enrich the people in Nanyang.

　　Today, the planting area of Dengzhou and Tongbai under the jurisdiction of Nanyang City has reached more than 40,000 mu, and the planting areas of Tanghe, Sheqi, Nanzhao, Wolong and Wancheng are all over 10,000 mu. In Nanyang, like Yin Zhehua, more and more poor households have found a way to get rich by planting and processing wormwood.

　　The data shows that at present, there are more than 160 varieties of wormwood products developed in Nanyang City, which are exported to 56 countries and regions along the "Belt and Road" with an output value of more than 20 billion yuan. Since 2017, two consecutive national wormwood industry conferences have been held in Nanyang.

　　Lengthening the industrial chain of enriching the people

　　In Xinzhuang Village, Tongzhaipu Town, tanghe county, the sign of "wormwood industry poverty alleviation base" is particularly eye-catching. This is the 3000-mu high-quality wormwood planting base of Nanyang Daai Ecological Agriculture Development Co., Ltd.. "We adopt ‘ Company+cooperative+poor households ’ The model provides poor households with one-stop services such as planting and technology, and signs a recycling agreement, which has achieved remarkable results in promoting local economic development and increasing farmers’ income. " The person in charge of the company introduced.

　　Planting "Ai" will increase income, and "Ai" will lift you out of poverty. "I participated in the whole process from planting and weeding to harvesting, drying and leaf stalk separation in the later stage. I didn’t expect that this wormwood can bring me more than 1,000 yuan a month. Really exciting! " Speaking of wormwood, Yu-fu Li, a poor household who works in Nanyang Daai Ecological Agriculture Company, smiles.

　　In the Ai products processing workshop of Jintiandi Agricultural Excellent Products Cooperative in Hongniwan Town, Wancheng District, the express boxes piled up in mountains attracted the attention of reporters. "Many shops in Taobao and JD.COM buy goods from us!" The person in charge of the cooperative proudly said, "The store sends the buyer’s information after receiving the order. I send the goods directly to all parts of the country in the factory, and the store has zero inventory, which also shortens the logistics chain, which is a win-win situation!"

　　In recent years, with the expansion of market demand, the purchase price of wormwood has increased year by year, and farmers have begun to plant high-quality wormwood. The wormwood industry featuring wormwood processing and moxibustion medical care has shown an increasingly prosperous momentum. According to the statistics of Nanyang wormwood Industry Association, at present, the average annual benefit of wormwood per mu can reach 3000 yuan, and the economic income of local farmers has been greatly improved by planting wormwood.

　　Taking wormwood as the starting point, participating in the "precise poverty alleviation" project to help poor households get rid of poverty and increase their income is just a microcosm of the rapid development of wormwood industry in Nanyang City. According to reports, Nanyang City is actively cultivating and expanding the wormwood industry, processing value-added, lengthening the chain, registering the "Wanai" trademark, and launching the brand, so that the wormwood industry can play the maximum benefit in industrial poverty alleviation.

　　Policy escort and steady income increase

　　Wormwood is a unique and rich resource of traditional Chinese medicine in China, and it is also a healthy tourism resource with great potential. In recent years, Nanyang Municipal Party Committee and Municipal Government have made the development of wormwood industry as the key content of the city’s big health industry, and successively issued Nanyang Life and Health Industry Action Plan (2015-2020), Nanyang 13th Five-Year Plan for Chinese Medicine Development, Zhang Zhongjing’s Major Special Implementation Plan for Health City, and Nanyang National Comprehensive Reform Experimental Zone Construction Implementation Plan and related supporting measures to build wormwood industrial park and vigorously support it.

　　Located in Qiaotou Town, Sheqi County, the wormwood planted by Nanyang Luying wormwood Biological Products Co., Ltd. is growing vigorously. The production and processing enterprises of mugwort products, led by Luying mugwort biological products company, have discovered the characteristics of high cashmere content and high volatile oil content of authentic mugwort in Nanyang, and developed nearly 100 kinds of products, such as traditional mugwort, smokeless mugwort, mugwort, mugwort granules, mugwort essential oil series and mini moxibustion series. The products are exported to dozens of countries and regions such as Japan, South Korea, Southeast Asia and Europe, with an annual output value of several hundred million yuan.

　　In today’s society, people’s use of wormwood is no longer limited to copying traditional Chinese herbal medicine culture, but researchers are constantly breaking through and studying its new value. With Nanyang Medical College’s "Nanyang Ai Products Engineering Technology Research Center" and Nanyang Institute of Technology’s "Zhang Zhongjing Provincial Key Laboratory of Prescription and Immunoregulation" as research platforms, through school-enterprise cooperation, a research and development team of wormwood industry was established to continuously promote the transformation of scientific and technological achievements.

　　Located between Dafengying Town and Qiaotou Town in Sheqi County, Nanyang Zhongjing wormwood Industry Group covers wormwood planting, wormwood product research and development, domestic and foreign trade, etc. The company has more than ten subsidiaries, and its China Medical Zhongjing Company is the largest wormwood planting enterprise in China, which has driven more than 1,500 neighbors to find jobs, created economic benefits and constantly fulfilled its social responsibilities.

　　Wormwood has been fragrant for thousands of years, and its industry is flourishing today. Nowadays, Nanyang wormwood industry is taking the road of green development and ecological poverty alleviation with unprecedented vigorous momentum, and is striving to write a glorious chapter of building a well-off society in an all-round way in the southwestern part of Henan.

　　Since the beginning of this year, the global Internet giants have set off a "hundred-model war", and Microsoft, Google, Baidu and Ali have come to the end one after another. After more than half a year of competition, technology giants are welcoming a new round of road disputes around the big model ecology: facing the parameter "ceiling", will the future of the big model be closed or open?

　　The open source model can run on a home computer.

　　On August 3rd, two open source models, Qwen-7B and Qwen-7B-Chat, were put on the domestic AI developer community "ModelScope", which were Alibaba Cloud Tongyi Qianwen’s 7 billion parameter general model and dialogue model respectively. Both models were open source, free and commercially available.

　　According to reports, Tongyi Qianwen Qwen-7B is a pedestal model that supports many languages such as Chinese and English, and it is trained on more than 2 trillion token (text unit) data sets, while Qwen-7B-Chat is a Chinese-English dialogue model based on the pedestal model, which has reached the cognitive level of human beings.In short, the former is like a "foundation" and the latter is a "house" on the foundation.

　　The actual test shows that the comprehensive performance of Qwen-7B model is good. Among them, on the English proficiency evaluation benchmark MMLU, the score is generally higher than that of the mainstream models with the same parameter scale, even surpassing some models with 12 billion and 13 billion parameter scales. On the Chinese evaluation C-Eval verification set, the model also achieved the highest score of the same scale. Qwen-7B model is also among the best in evaluating GSM8K in mathematical problem solving ability and HumanEval in code ability.

　　That is to say,In the tests of Chinese and English writing, solving mathematical problems and writing codes, Qwen-7B model is properly a "master of learning", and its score even exceeds the international mainstream model with the same parameter level.

　　Besides, the industry is more concerned about the usability of Qwen-7B model. As we all know, the training and operation of mainstream large models need special AI training chips (such as NVIDIA A100), which are not only expensive, but also as high as 10,000 — per NVIDIA A100; 15,000 dollars, and it is monopolized by countries such as Europe and the United States, and it is almost impossible to buy it in China.The domestic Qwen-7B model supports the deployment of consumer graphics cards, which is equivalent to a high-performance home computer to run the model.

　　Thanks to free commercialization and low threshold, the Qwen-7B model has been put on the shelves, which has attracted the attention of AI developers.In just one day, on the code hosting platform GitHub, the Qwen-7B model has been collected by more than a thousand developers, and most of the questioners are Chinese developers.As Alibaba Cloud said in the statement: "Compared with the lively AI open source ecology in the English-speaking world, the Chinese community lacks an excellent pedestal model. The addition of Tongyi Qianwen is expected to provide more choices for the open source community and promote the open source ecological construction of AI in China. "

　　Open source or closed?

　　In fact, Qwen-7B model is not the first big open source model. In fact, GPT-2, the predecessor of ChatGPT, is also completely open source. Its code and framework can be used for free on the Internet, and related papers can be consulted. However, after ChatGPT spread all over the world, OpenAI chose closed-source development, and the model codes such as GPT-3 and GPT-4 have become the trade secrets of OpenAI.

　　The so-called open source is open source code.For example, once the big model is declared open source, anyone can publicly obtain the model source code, modify it or even redevelop it within the scope of copyright restrictions. To make a simple analogy,The source code is like the manuscript of a painting, and everyone can fill in the colors according to the manuscript to create their own artistic paintings.

　　Closed source is just the opposite of open source.Only the source code owner (usually the software developer) has the power to modify the code, others can’t get the "manuscript" and can only buy the finished product from the software developer.

　　The advantages and disadvantages of open source and closed source are very obvious. After open source, the big model will undoubtedly attract more developers, and the application of the big model will be more abundant, but the corresponding supervision and commercialization will become a difficult problem, which is prone to the embarrassing situation of "making wedding clothes for others".After all, open source considers ecological co-prosperity, and it is difficult to figure out the economic account of how much money can be earned at this stage, and these problems happen to be opportunities to close the source.

　　Open source or closed source, this is a big model of life and death, the international giants have given the answer.

　　Meta, the parent company of Facebook, released the big model Llama2 last month, which is open source and free for developers and business partners, while OpenAI firmly chose GPT-4 closed source development, which not only can maintain OpenAI’s leading position in the generative AI industry, but also can earn more revenue. According to the authoritative magazine Fast Company,OpenAI’s revenue in 2023 will reach 200 million US dollars, including providing API data interface services and subscription service fees for chat bots.

　　Domestic big models have gradually begun to "go their separate ways".Alibaba Cloud’s General Meaning ModelAs early as April this year, it was announced to be open to enterprises, and the open source of Qwen-7B model will go further.ERNIE Bot of BaiduIt has also recently announced that it will gradually open the plug-in ecosystem to third-party developers to help developers build their own applications based on the Wenxin model.

　　In contrast, Huawei does not take the usual path. When the Pangu Big Model 3.0 was released, Huawei Cloud publicly stated that,Pangu modelThe full stack technology is independently innovated by Huawei, and no open source technology is adopted. At the same time, Pangu Big Model will gather numerous industry big data (involving industry secrets, etc.), so Pangu Big Model will not be open source in the future.

　　The big parameters are still small and beautiful.

　　In addition, the open source of Qwen-7B model brings another thought:How many parameters do we need a big model?

　　There is no denying that,The parameter scale of the large model is constantly expanding.Take the GPT model under OpenAI as an example. GPT-1 only contains 117 million parameters, and the parameters of GPT-3 have reached 175 billion, which has increased by more than 1000 times in a few years, while the parameters of GPT-4 have exceeded the trillion level.

　　The same is true of large domestic models. Baidu Wenxin model has 260 billion parameters, Tencent mixed-element model has reached 100 billion parameters, Huawei Pangu model has been estimated to be close to GPT-3.5, and ali tong Yida model has officially announced 10 trillion parameters … …According to incomplete statistics, there are at least 79 large-scale models with over 1 billion parameters in China.

　　Unfortunately, the larger the parameter, the stronger the capability of the large model. At the World Artificial Intelligence Conference, Wu Yunsheng, vice president of Tencent Cloud, has a very appropriate metaphor: "Just like athletes practicing physical strength, weightlifters need to lift 200 kilograms of barbells, and swimmers need to lift 100 kilograms. Different types of athletes don’t need everyone to practice 200 kilograms of barbells."

　　As we all know,The higher the parameters of the large model, the more resources and costs are consumed.However, it is not necessary to blindly pursue "large scale" or "high parameters" to deepen the vertical large-scale model of the industry, but to formulate relevant model parameters according to customer needs. For example, the BioGPT-Large model has only 1.5 billion parameters, but its accuracy in biomedical professional tests is better than that of the general model with 100 billion parameters.

　　Sam Altman, co-founder of OpenAI, also publicly stated that OpenAI is approaching the limit of LLM (Large Language Model) scale. The larger the scale, the better the model is, and the parameter scale is no longer an important indicator to measure the quality of the model.

　　Wu Di, the head of intelligent algorithm in Volcano Engine, has a similar view. In the long run, reducing costs will become an important factor in the application of large models. "A well-tuned small and medium-sized model may perform as well as a general large model in a specific job, and the cost may be only one tenth of the original."

　　At present, almost all domestic science and technology manufacturers have got tickets for big models, but the real road choice has just begun.

　　2017 is a milestone in the development of integration of defense and civilian technologies in China. This year, the Central integration of defense and civilian technologies Development Committee was established and operated efficiently, and its strategic guidance and overall planning were comprehensively strengthened. This year, integration of defense and civilian technologies’s development strategy was fully implemented, and the system was established, the pattern was fixed, and new plans were broken. integration of defense and civilian technologies’s development events were frequent. This year, the 19th National Congress of the Communist Party of China was successfully held, which defined the course and voyage of integration of defense and civilian technologies’s development, deployed the short-term tasks, drew a blueprint for the future and injected new impetus. This year, major reforms in integration of defense and civilian technologies were significantly accelerated, and a series of policies were launched intensively. integration of defense and civilian technologies’s development boom surged and entered a new era.

　　1. usher in the most profound qualitative change

　　The 19th National Congress of the Communist Party of China held in October 2017 made a series of arrangements and long-term plans for integration of defense and civilian technologies. The report of the 19th National Congress of the Communist Party of China emphasized "integration of defense and civilian technologies" in three places, profoundly expounded the theoretical guidance, strategic position, development goals and key tasks of integration of defense and civilian technologies’s development in the new era, and further highlighted integration of defense and civilian technologies’s strategic position in strengthening the country and the army. The 19th National Congress established the guiding position of the supreme leader’s thought of strengthening the army in national defense and army building, and formally regarded the development of integration of defense and civilian technologies as an important part of the supreme leader’s Socialism with Chinese characteristics Thought in the new era, and incorporated it into the scientific system of the supreme leader’s thought of strengthening the army, which provided a scientific guide and program of action for promoting integration of defense and civilian technologies’s development and realizing the dream of strengthening the army and strengthening the country in the new era.

　　The 19th National Congress of the Communist Party of China listed integration of defense and civilian technologies’s development strategy as one of the seven national strategies to start a new journey of building a socialist modern country in an all-round way, and wrote the firm implementation of integration of defense and civilian technologies’s development strategy into Constitution of the Communist Party of China, further highlighting the important position of integration of defense and civilian technologies’s development strategy in the national strategic system. This will be a major national strategy that runs through the whole process of building a world-class army and building a socialist modern power in an all-round way. By establishing such a strategic orientation, our Party will be able to give full play to the political advantages of unified leadership, the institutional advantages of socialist concentrated efforts to do great things, stimulate the creative spirit and patriotic enthusiasm of hundreds of millions of people throughout the country, and do a good job in implementing the development strategy of integration of defense and civilian technologies.

　　The report of the 19th National Congress of the Communist Party of China emphasized the formation of integration of defense and civilian technologies’s deep development pattern, the construction of an integrated national strategic system and capabilities, and the clear direction of integration of defense and civilian technologies’s development in the new era. To build an integrated national strategic system and capability is to reshape the national security and development strategic system, completely eliminate the dual separation of military and civilian, promote the integrated allocation of military and civilian resources and the integrated use of military and civilian forces, realize the overall planning of national development and security, the integrated development of economic construction and national defense construction, and the simultaneous improvement of economic strength and national defense strength, comprehensively enhance the country’s comprehensive strength and strategic competitiveness, and provide strategic support for building a socialist modern power. The report of the 19th National Congress of the Communist Party of China defined the key tasks of integration of defense and civilian technologies’s development in the new era, and emphasized the need to strengthen unified leadership, top-level design, reform and innovation, and the implementation of major projects, and deepen the reform of national defense science, technology and industry. This task deployment focuses on political guarantee, strategic planning, system construction and project implementation, and establishes the basic focus of implementing integration of defense and civilian technologies’s development strategy.

　　To promote the in-depth development of integration of defense and civilian technologies, it is difficult to break through the institutional bottleneck. It has become an important historical task to break the institutional mechanism and the interest barrier behind it to promote the development of integration of defense and civilian technologies. At the beginning of the new year in 2017, the Political Bureau of the Communist Party of China (CPC) Central Committee held a meeting and decided to set up the Central integration of defense and civilian technologies Development Committee, with the Chairman of the Supreme Leader as its director. As soon as the news came out, it quickly triggered widespread concern at home and abroad and heated public opinion. The establishment of this major institution has established a unified leadership system for integration of defense and civilian technologies’s development from the top-level institutional framework of state governance, and strengthened unified leadership and overall decision-making on major issues in integration of defense and civilian technologies across military areas, fields and systems. It is a major reform and innovation of China’s national defense system and mechanism, which has far-reaching historical significance.

　　In 2017, people strongly felt that it was normal for the Central integration of defense and civilian technologies Development Committee to hold regular meetings to study and decide on major issues of integration of defense and civilian technologies’s development. On June 20th, the Central integration of defense and civilian technologies Development Committee held its first plenary meeting, and deliberated and adopted the Working Rules of the Central integration of defense and civilian technologies Development Committee, the Recent Work Points of the Central integration of defense and civilian technologies Development Committee, and the Opinions on the Establishment of Development Leading Institutions and Working Institutions in integration of defense and civilian technologies Province (autonomous regions and municipalities). On September 22nd, the integration of defense and civilian technologies Development Committee of the Central Committee held its second plenary meeting, focusing on the tasks of integration of defense and civilian technologies of national defense science, technology and industry, socialization of military support, and implementation of national defense requirements for major infrastructure. Integration of defense and civilian technologies’s development has entered the fast lane of improving quality and increasing efficiency.

　　All provinces (autonomous regions and municipalities directly under the Central Government) have set up provincial-level integration of defense and civilian technologies development leading bodies and working bodies based on local conditions and in accordance with the principle of "real need, simplification and high efficiency". By the end of December last year, the party committees of 31 provinces, municipalities and autonomous regions had successively set up leading bodies in integration of defense and civilian technologies. At the same time, military-related reforms have been accelerated. In 2017, a new institution in the People’s Army — — With the birth of the Military Scientific Research Steering Committee of the Central Military Commission, together with the Science and Technology Committee of the Military Commission, China’s national defense science and technology innovation has a brand-new top-level structure, and the construction of integration of defense and civilian technologies’s innovation system has a strong institutional support.

　　In 2017, the development system of integration of defense and civilian technologies ushered in the most profound qualitative change in the past 40 years of reform and opening-up, and established the working pattern of overall decision-making by the committee, comprehensive coordination of the office, and division of responsibilities between the military and local departments, and made great progress in building a vertically integrated, horizontally coordinated, smooth and efficient organization and management system in integration of defense and civilian technologies.

　　2. The policy and institutional environment has been continuously optimized.

　　To promote the in-depth development of integration of defense and civilian technologies, it is basically to promote the transformation of economic construction and national defense construction from fragmented design to integrated military and civilian planning, from key integration areas to multi-field extension and expansion, from loose combination of factors to integration and integration of all factors, and then realize the process of structural optimization, resource conservation and technological innovation.

　　2017 is a year of frequent major policy system reform initiatives in integration of defense and civilian technologies. Relevant policies and measures have been introduced at all levels in the military and civilian areas. The fiscal, taxation and financial policies related to integration of defense and civilian technologies’s development have been further improved, the channels for ensuring funds have been continuously expanded, and the institutional environment for integration of defense and civilian technologies’s development policies has been continuously optimized.

　　Major reforms have been further accelerated. The reform of the first batch of 41 military scientific research institutes was implemented, and the reform schemes such as airspace management system, military pricing bargaining rules and equipment procurement system were further demonstrated. The "weapons and equipment quality management system certification" and "equipment contractor qualification examination" were integrated, and the working mechanism of joint examination of weapons and equipment research and production licenses and equipment contractors was comprehensively promoted. We will promote the integration and sharing of large-scale military and civilian defense scientific research instruments and equipment, the innovative cooperation of military-civilian dual-use technology alliance with equity as the link, and the identification and access standards of supporting core military products for civilian enterprises throughout the country.

　　Major policies were launched intensively. On August 23rd, the Ministry of Science and Technology and the Science and Technology Committee of the Military Commission publicly released the Special Plan for the Development of Science and Technology integration of defense and civilian technologies in the 13th Five-Year Plan. On September 22nd, the second plenary session of the Central integration of defense and civilian technologies Development Committee deliberated and adopted the 13th Five-Year Plan for the Development of National Defense Science, Technology and Industry, Opinions on Promoting the Deep Development of National Defense Science, Technology and Industry in integration of defense and civilian technologies and Implementation Opinions on Promoting the Deep Development of Military Logistics in integration of defense and civilian technologies during the 13th Five-Year Plan. On November 23rd, the General Office of the State Council issued "Opinions on Promoting the Deep Development of National Defense Science, Technology and Industry in integration of defense and civilian technologies", which contained high gold content and sent a strong signal to the outside world to break the boundary between military industry and civilian population and break through the barriers of ownership.

　　Only by integrating according to law can we be stable and far-reaching. In January 2017, People’s Republic of China (PRC)’s National Defense Traffic Law came into effect, which is the first basic law in the history of the Republic to specifically regulate national defense traffic activities. It is also the first national defense legislation in China since the 18th National Congress of the Communist Party of China, bearing the great mission of solving the development problems of integration of defense and civilian technologies by the rule of law. Integration of defense and civilian technologies’s comprehensive legal legislation has been stepped up, integration of defense and civilian technologies’s laws and regulations have been enacted, revised, abolished and interpreted in different fields, policy documents and standards that are not suitable for integration of defense and civilian technologies’s development have been comprehensively cleaned up, abolished and revised, and local policies and regulations that support integration of defense and civilian technologies’s development have been promulgated one after another, and integration of defense and civilian technologies’s environment for developing the rule of law has gradually taken shape.

　　Promote integration through openness. In 2017, a series of real tricks for information disclosure and market opening occurred frequently. In order to "wake up" the national defense patent "Sleeping Beauty" status, on March 6, the Equipment Development Department of the Central Military Commission released 2346 pieces of national defense patent decryption information for the first time, boosting the transfer and transformation of national defense patent technology to the civilian field. On September 25th, the national defense intellectual property information platform was put into operation and provided information inquiry service, aiming at solving the problem of poor communication and sharing channels of national defense patent information. In the two years since the PLA’s weapons and equipment procurement information network was launched, more than 11,900 registered and certified enterprise users have published more than 7,500 pieces of military equipment procurement information, and more than 5,000 pieces of superior products and technologies recommended by enterprises have been made public in military demand information, effectively building a platform for online supply and demand information docking. For the first time, our army published the guide of equipment pre-research project online, which opened the door to participate in national defense science and technology innovation for high-quality social resources. In late May, the Logistics Support Department of the Military Commission issued 63 military logistics open scientific research projects, and selected research units for local open competition, marking an important step in the development of integration of defense and civilian technologies in the field of military logistics science and technology.

　　3. Combat effectiveness and productivity have achieved double improvement.

　　On October 23, 2017, a news aroused great concern in the society: Air Force Logistics Department signed strategic cooperation agreements with five leading local logistics enterprises, including Shunfeng Group, China Railway Express, China Post Express, Debon Logistics and Jingdong Logistics, to promote logistics and logistics in integration of defense and civilian technologies in a "systematic, integrated and full coverage" way. This exploration shows a general trend of the times. It can be predicted that the in-depth development of integration of defense and civilian technologies will set off an all-round military management revolution, completely change the traditional self-contained and relatively closed development model, and absorb and apply the most advanced knowledge, cutting-edge technology and top-quality talent resources in the economic society to the construction of modern services.

　　In 2017, based on their own advantages, all localities implemented integration of defense and civilian technologies’s development strategy and innovation-driven development strategy as a whole, and took integration of defense and civilian technologies’s development as an important part of promoting supply-side structural reform. They implemented differentiated development according to local conditions, actively created a new pattern of regional integration of defense and civilian technologies’s development with different characteristics and emphases, and made efforts to create new development momentum and expand new development space. Some provinces and cities have formulated opinions and planning plans for the implementation of integration of defense and civilian technologies’s development, boldly explored new mechanisms and new modes of military-to-civilian, civilian-to-army and military-civilian collaborative innovation, vigorously promoted military-civilian technology integration, product integration, capital integration and talent integration, and successively built a number of platforms for information sharing, open innovation, investment and financing, incubation and transformation, so as to fully tap the development potential of integration of defense and civilian technologies in this region. Some local governments take integration of defense and civilian technologies-related industries as high-end industries that will lead the future development, and launch a series of genuine policies and measures to support the development of regional integration of defense and civilian technologies, making efforts to build industrial clusters in integration of defense and civilian technologies and cultivate and tap new economic growth points. It is the organic combination and interaction between the visible hand of the government and the invisible hand of the market that the government creates the environment — Innovative entrepreneurs gather — Enterprise agglomeration — Industrial agglomeration — The economy is bigger and stronger — A virtuous circle pattern of enhanced integration and development potential is accelerating in some key areas.

　　With the continuous efforts of the military and civilian levels, integration of defense and civilian technologies’s "Ren Du Er mai" is being opened, which has promoted the double promotion of combat effectiveness and productivity and accelerated the generation of integrated national strategic capabilities. Major demonstration projects deployed in the 13th Five-Year Plan have been launched, and a number of major projects are being accelerated. At the third integration of defense and civilian technologies Exhibition on the Achievements of Developing High-tech Equipment, 422 integration of defense and civilian technologies innovations from 354 enterprises in China made a wonderful appearance, and a large number of scientific and technological innovations were exciting. Beidou satellite navigation system, the national quantum secure communication "Beijing-Shanghai trunk line", Shenwei Taihu Light Supercomputer and other national heavyweights made public appearances. Over the past year, Chang ‘e III has achieved the first soft landing of extraterrestrial objects and the automatic inspection of the lunar surface, and the manned space missions of Tiangong-2 and Shenzhou-11 have been successfully completed. Beidou-3 began global networking, and the accuracy of providing services for the Asia-Pacific region has reached the meter level. Beidou-3 began global networking, and the accuracy of providing services for the Asia-Pacific region has reached the meter level. The first flight of C919, a large aircraft, and the first flight of a new generation of large and medium-sized launch vehicles were successfully completed, and many major technological breakthroughs were made in the special projects of aero-engine and gas turbine. Significant progress has been made in the special project of "Nuclear High Base", and the independent guarantee rate of core electronic devices of supporting equipment has been increased from less than 30% to 85%, and the problem of "sticking neck" of core electronic devices that have long relied on imports has been alleviated. Over the past year,The transformation of military and civilian technology has been accelerated, such as "air conditioning vest", "missile" for fire fighting, ground penetrating radar for "CT scanning" of underground pipelines, and unmanned aerial vehicle & HELIP, which is monitored 24 hours a day; … A large number of high-end scientific and technological achievements are also benefiting society.

　　I will ride the wind and break the heavy waves some day, and then set the cloudlike sail and cross the sea. The coming period is not only an opportunity period to promote the deep integration of military and civilian, but also a crucial period to break the dual separation of military and civilian. We must firmly grasp the historical opportunity, overcome difficulties, forge ahead, and work together with the military and the people to accelerate the formation of a deep development pattern in integration of defense and civilian technologies.

　　　　　　　 Directed by Liu Zhenwei, Zheng Zhongji, Athena Chu, Liang Yongqi, Ada Choi, Bo Huang, Degang Guo and other 58 top Chinese comedy stars will join in the upcoming release on March 18th. Bo Huang and Ceng Zhiwei play Zhou Yu and Zhuge Liang respectively in the film, and Bo Huang, as the new film winner, and Ceng Zhiwei, the eldest brother of Hong Kong film industry, have unexpected "hot" performances in the film.

Bo Huang’s version of "Rock" Zhou Yuwen is both civil and military.

　　　　　　　 Yue Guang Bao Box is a film with Liu Zhenwei-style love and comedy elements as the main line. The film takes the road of "all-in-one suit" as the main line and shuttles through the time and space of various classic movies. Among them, Red Cliff is the highlight of the whole film, and most of the plots in the film take place in the time and space of Wu Yusen’s Red Cliff. Liu Zhenwei, who is humorous by nature, invited Bo Huang, the new winner of Golden Horse, to play Zhou Yu, but the Bo Huang version of Zhou Yu was 3 points more "shocking" and funny than that played by Tony Leung Chiu Wai.

　　　　　　　 In Yue Guang Bao Box, Bo Huang’s version of Zhou Yu not only fought fiercely with Zhuge Liang played by Ceng Zhiwei, but also fought at the altar of borrowing the east wind, changing the image of Tony Leung Chiu Wai’s version of Zhou Yu’s elegance. However, the two were not completely antagonistic in the film. In order to show that Zhou Yu and Zhuge Liang appreciate each other were fighting against Cao Cao, Director Liu Zhenwei specially arranged for them to play a piece of fiddle together, but they finally turned a piece of "Mountain Flowing Water" into a live version of the rock chorus, which shocked the audience all over the place.

Bo Huang beat up Ceng Zhiwei on the set.

　　　　　　　 Although the main line of Yue Guang Bao Box is the chase-and-run love between Zheng Zhongji and Sun Li, the scene of the battle at Chibi is also very heavy. The director not only spends a lot of energy to reproduce all the war scenes in Battle of Red Cliffs, but also reinterprets the war with his own methods. Among them, "borrowing from the east wind" is the highlight of the scene, but in this scene, Bo Huang actually fights with the old-timer Ceng Zhiwei, and Ceng Zhiwei does not show weakness at the scene and grabs bananas as weapons to fight back.

　　　　　　　 It turned out that under Liu Zhenwei’s "provocation", in the scene of borrowing the east wind, Zhou Yu, played by Bo Huang, defied Zhuge Liang, played by Ceng Zhiwei, and said, "I found out how you borrowed everything, and the arrow was borrowed. Two days ago, you encouraged your master to borrow Jingzhou, and now you are borrowing the east wind. Really, alas ~ ~", Ceng Zhiwei, who was angry, grabbed the banana on the altar and tore it with Bo Huang.

　　　　　　　 Funnily enough, according to the staff, director Liu Zhenwei paid special attention to this play, and not only specifically asked Bo Huang to really hit hard, but also repeatedly NG for more than ten times before letting Ceng Zhiwei go. I don’t know if the two had any historical grievances, but it is unclear whether Bo Huang, who had the opportunity to punch the doyen for the first time, was also in a dark mood. The film will be released globally simultaneously on March 18th.

　　Xinhua News Agency, Beijing, April 18th Question: The key data of the first quarter was released. What do you think of the current economic situation?

　　Xinhua News Agency "Xinhua Viewpoint" reporter

　　In 2023, the first quarterly report of China’s economy was released on the 18th: the gross domestic product (GDP) was 28,499.7 billion yuan, a year-on-year increase of 4.5%.

　　On April 18th, the State Council Press Office held a press conference in Beijing. Fu Linghui, spokesperson of the National Bureau of Statistics and director of the National Economic Statistics Department, introduced the operation of the national economy in the first quarter of 2023 and answered questions from reporters. Xinhua News Agency reporter Cai Yang photo

　　Facing the severe and complicated international environment and arduous domestic reform, development and stability tasks, China’s economy has made a good start. What do you think of this report card? The "Xinhua Viewpoint" reporter combed the key data.

　　GDP increased by 4.5% year-on-year: the economy stabilized and rebounded.

　　In the first quarter, GDP increased by 4.5% year-on-year, and the growth rate was 1.6 percentage points higher than that in the fourth quarter of last year; The chain increased by 2.2%.

　　"With the rapid and smooth transition of epidemic prevention and control, various policies and measures to stabilize growth, employment and prices have been put forward, positive factors have accumulated and the national economy has stabilized and rebounded." Fu Linghui, spokesman of the National Bureau of Statistics, said.

　　Since the beginning of this year, the World Bank and other international organizations have raised the economic growth forecast of China. "Under the current situation that the overall recovery of the world economy is weak, China’s economy has shown a positive momentum and injected beneficial increments into global growth." World Bank President Malpas said.

　　Fu Linghui said that considering the low base affected by the epidemic in the second quarter of last year, the economic growth rate in the second quarter of this year may be significantly faster than that in the first quarter; With the increase of the base, the growth rate will fall back in the third and fourth quarters. On the whole, however, the endogenous driving force of China’s economic growth is gradually enhanced, and the macro-policies are effective, and the economic operation is expected to improve as a whole.

　　Total consumption exceeds 11 trillion yuan: the overall recovery is improving.

　　In the first quarter, the total retail sales of consumer goods in China was 11,492.2 billion yuan, up 5.8% year-on-year, down 2.7% in the fourth quarter of last year; The contribution rate of final consumption expenditure to economic growth reached 66.6%.

　　With the gradual release of residents’ consumption demand, the growth of upgrading consumption has accelerated, and the consumption of basic life has continued to grow. In the first quarter, the retail sales of goods increased by 4.9% year-on-year, and decreased by 1.7% in the fourth quarter of last year.

　　"The overall consumption has shown a good recovery trend." Fu Linghui said that with the continuous efforts of the consumption promotion policy, the market sales have rebounded significantly, especially the service consumption has improved significantly, and the consumption has significantly enhanced the economic growth.

　　Yang Guangpu, an associate researcher at the State Council Development Research Center, said that at present, efforts should still be made to enhance residents’ confidence and ability in consumption, do everything possible to increase residents’ income, so that people can spend more confidently, and actively increase quality supply, effectively combine consumption expansion with supply-side structural reform, and continuously release consumption potential.

　　Fixed assets investment increased by 5.1% year-on-year: the steady growth of investment is expected to continue.

　　In the first quarter, the national investment in fixed assets increased by 5.1% year-on-year, which was the same as that of the previous year.

　　Fu Linghui said that since the beginning of this year, China has insisted on expanding domestic demand, actively played the key role of investment in optimizing the supply structure, increased investment in key areas and key links, and expanded investment in people’s livelihood, effectively safeguarding and improving people’s lives. The steady growth of investment has effectively enhanced the development potential.

　　It is worth noting that investment in high-tech industries grew rapidly in the first quarter, with a year-on-year increase of 16%. "The rapid development of high-tech industries is conducive to further enhancing the resilience of China’s industrial chain supply chain, and is conducive to continuously improving China’s industrial added value and its strength in global industrial competition." Xu Zhaoyuan, deputy director of the Industrial Economics Research Department of the State Council Development Research Center, said.

　　Yang Guangpu said that with the sustained economic recovery, the technological transformation, transformation and upgrading of traditional industries are expected to accelerate, digital transformation and green and low-carbon transformation continue to advance, and with the implementation of various support policies, investment is expected to maintain steady growth.

　　Foreign trade increased by 4.8% year-on-year: export growth was higher than expected.

　　In the first quarter, the total import and export value of China’s goods trade was 9.89 trillion yuan, a year-on-year increase of 4.8%. In March, the total import and export value was 3.71 trillion yuan, up 15.5% year-on-year, of which exports increased by 23.4% year-on-year and imports increased by 6.1%.

　　Lu Daliang, director of the Statistics and Analysis Department of the General Administration of Customs, said that since the beginning of this year, China’s economic operation has stabilized and rebounded, production and demand have gradually improved, and foreign trade imports and exports have stabilized significantly. "In the first quarter, China’s foreign trade import and export showed strong resilience, and the start was stable and good, laying the foundation for achieving stable and improved foreign trade throughout the year."

　　Zhuang Rui, a professor at university of international business and economics, said that the rapid export growth is mainly reflected in the bright export of electromechanical and high-tech products represented by new energy vehicles, as well as the improvement of export growth to countries along the Belt and Road Initiative and countries with regional comprehensive economic partnership agreements (RCEP) and other trading partners. In addition, due to the narrowing of the year-on-year increase in international commodity prices, the growth rate of imports is relatively low.

　　CPI rose by 1.3% year-on-year: prices remained stable.

　　In the first quarter, the national consumer price index (CPI) rose by 1.3% year-on-year, maintaining a moderate increase, and domestic prices continued to run smoothly.

　　Stabilizing prices is an important task for doing a good job in economic work this year. Fu Linghui said that the CPI increase continued to fall, mainly affected by some stage factors: after the Spring Festival, the market demand fell, the weather turned warmer, the listing of fresh vegetables increased more, and the prices of some foods fell; The supply of live pigs is sufficient and the price of pork has declined; The international energy market, especially the crude oil market, has generally declined, which has led to lower domestic energy prices and so on.

　　Although the increase of CPI has declined, the market supply and demand have remained basically stable. In the first quarter, the core CPI excluding food and energy prices rose by 0.8% year-on-year, which was the same as that in January and February.

　　"Looking forward to the whole year, China’s industrial and agricultural products and services are well supplied, production and marketing are smoothly connected, the market order is good, and the overall economic recovery trend will gradually appear in prices. It is expected that the overall price level will generally operate in a reasonable range." Guo Liyan, director of the Comprehensive Situation Research Office of China Macroeconomic Research Institute, said.

　　PPI decreased by 1.6% year-on-year: it is expected to gradually return to a reasonable level.

　　In the first quarter, the national producer price index (PPI) decreased by 1.6% year-on-year, of which the price of means of production decreased by 2.3%.

　　Fu Linghui said that since the beginning of this year, world economic growth has slowed down, market demand has weakened, supply bottlenecks have eased, and commodity prices have fallen, which has driven down the prices of domestic oil, nonferrous metals and other related industries. In addition, the high base in the same period last year has led to a decline in PPI. Expanded.

　　Judging from the ring comparison, the PPI is basically stable. In January, PPI decreased by 0.4% month-on-month, while in February and March, it was flat.

　　Fu Linghui said that from the next stage, domestic demand generally tends to pick up, which has a certain pull-up effect on PPI, but the import transmission of international commodity prices still exists, and with the high base in the same period last year, PPI may be in a downward range in the short term. However, with the recovery of domestic economy, cardinal utility will gradually decline, and PPI will gradually return to a reasonable level.

　　The national industrial added value increased by 3% year-on-year: achieving steady growth.

　　In the first quarter, the added value of industrial enterprises above designated size increased by 3% year-on-year, and the growth rate was 0.3 percentage points faster than that in the fourth quarter of last year.

　　From the perspective of industry, among the 41 major industries in the first quarter, 23 industries maintained growth year-on-year, with a growth rate of over 50%. Compared with the fourth quarter of last year, the growth rate of added value of 20 industries rebounded.

　　Production of small and micro enterprises has improved. In the first quarter, the added value of small and micro enterprises above designated size increased by 3.1% year on year. According to the questionnaire survey, the prosperity index of small and micro-industrial enterprises under the regulations increased by 1.7 percentage points over the fourth quarter of last year, and the proportion of enterprises with good production and operation conditions increased by 1.2 percentage points.

　　"In the first quarter, the steady growth policy continued to be effective, the market demand picked up, the supply chain of the industrial chain accelerated to recover, and industrial production showed positive changes, but there was uncertainty in the growth of external demand, and the prices of industrial products were still falling." Fu Linghui said that in the next stage, it is necessary to deepen the structural reform of the supply side, vigorously transform and upgrade traditional industries, cultivate and expand emerging industries, and promote the healthy development of industries.

　　The average unemployment rate in national urban surveys is 5.5%: the employment situation has improved.

　　In the first quarter, the national urban survey unemployment rate averaged 5.5%, down 0.1 percentage point from the fourth quarter of last year. Among them, the urban survey unemployment rate in March was 5.3%, down 0.3 percentage points from February.

　　In March, the unemployment rate of the labor force aged 25 to 59 was 4.3%, down 0.5 percentage points from the previous month; The unemployment rate of migrant agricultural registered labor decreased by 0.7 percentage points from last month … … The unemployment rate of the main employment groups has dropped significantly, and the employment of migrant workers has accelerated.

　　Stabilizing business entities is the key to stabilizing employment. The Ministry of Human Resources and Social Security and other three departments have issued a notice at the end of March, which will continue to implement the policy of reducing unemployment and industrial injury insurance rates until the end of 2024. It is estimated that the average annual burden reduction this year and next will be about 180 billion yuan, and all kinds of business entities including small and medium-sized enterprises will generally benefit.

　　Fu Linghui said that with the economic recovery and the expansion of employment demand, the employment situation is expected to continue to improve. However, in view of the structural contradiction of employment, we should continue to increase employment assistance for young people, especially college graduates, accelerate the pace of industrial upgrading, and provide more high-quality jobs.
