Xinhua News Agency, Beijing, July 1 ST: Midstream hits the water and breaks the waves — — From the grassroots research to the first half of China’s economy in 2019

　　Xinhua news agency reporter

　　By the middle of 2019, China’s economy has gone through an extraordinary first half.

　　Ten years after the international financial crisis, the world economy has once again come to a crossroads. There are headwinds from trade protectionism and unilateralism, internal structural and cyclical contradictions are prominent, and the transformation and upgrading have climbed over the hurdle. How can China’s economic giant hit the water?

　　Sail and break the waves, and March forward against the wind. Xinhua News Agency reporters felt in the grass-roots investigation that the vivid stories of reform and innovation and the touching stories of forging ahead one by one constitute a vivid picture of China’s current economic stability and high-quality development.

　　What is the economic performance of China? — — Highlight a word "stability"

　　Rolling along the Yangtze River, it is rushing endlessly.

　　Nanjing, the central city in the lower reaches of the Yangtze River. At noon in midsummer, Luo Qun, member of the Standing Committee of Nanjing Municipal Committee of Jiangsu Province and full-time deputy secretary of the Party Working Committee of Jiangbei New District, met the reporter face to face. The opening remarks were actually throwing questions at himself: "How can the new district break through in the face of complex international economic and trade situation?"

　　As the 13th national new district in China, Jiangbei New District has developed continuously and rapidly since its establishment four years ago, making every effort to build an important engine for the high-quality development of Nanjing and even the Yangtze River Delta. However, in recent days, some enterprises have been affected by Sino-US economic and trade frictions, and the industrial growth rate of the new district has declined.

　　"It is also organic in danger, and the challenge is testing. This is a stage of physical fitness." Luo Qun said frankly that since the beginning of this year, the new district has made a fuss about reform, exerted its strength on the mechanism, adhered to innovation as the guide, and strived to make the development of the new district more stable and solid.

　　According to reports, Jiangbei New District attracted about 2,800 overseas talents to work in the first quarter. It is expected that more than 300 high-tech enterprises will be added this year, and the number of new R&D institutions and high-level talents has also maintained a high growth rate last year.

　　Along the river, we came to Chongqing.

　　Affected by the decline in automobile production and sales, the growth rate of added value of industrial enterprises above designated size in this southwestern town last year was only 0.5%. However, in the first five months of this year, the industrial growth rate rebounded to 4.8%, showing a stable and positive trend.

　　"Chongqing is based on manufacturing, and it also depends on manufacturing to move towards the future." Tu Xingyong, deputy director of Chongqing Economic Information Committee, said that Chongqing will consolidate and upgrade the "core screen nuclear network", that is, the whole industrial chain intelligent industrial cluster of chips, LCD panels, intelligent terminals, core components and the Internet of Things, and the automobile and motorcycle industrial cluster with new energy and intelligent network connection as the main direction, and promote the manufacturing industry to move towards the middle and high end.

　　"With ‘ Core screen device core network ’ We can ‘ develop. Calm down ’ 。” Tu Xingyong said humorously.

　　Look at the whole situation.

　　This is a true portrayal of China’s economy: there are many difficulties, but there is greater hope; There are many challenges, but more confidence.

　　A few days ago, Xinhua News Agency sent multi-channel teams to the grassroots level to see the local development trends, listen to the first-line voices of enterprises, explore the market circulation situation, and get a close look at the economic trends.

　　"Stability" is a clear feeling reached by journalists from all walks of life — —

　　In the first half of 2019, China’s economy gained momentum steadily.

　　Where is the stability?

　　The main driving force for economic growth is generally "stable": from the perspective of the "troika" of investment, consumption and export, in the first five months, although the growth rate of investment declined, the growth rate of manufacturing investment rebounded at a low level. In May, the growth rate of total retail sales of social consumer goods rebounded by 1.4 percentage points from the previous month, and exports increased by 7.7% year-on-year.

　　The employment and price indicators related to people’s lives are "stable": in May, the national urban survey unemployment rate was 5%, and in the first five months, 5.97 million new jobs were created in cities and towns nationwide, and more than half of the annual plan was completed; In May, the national consumer price rose by 2.7% year-on-year, with a moderate increase.

　　The pace of industrial structure optimization is "steady": in May, the added value of high-tech manufacturing increased by 9.4% year-on-year, 4.4 percentage points faster than that of industries above designated size; The growth rate of information transmission, software and information technology services is faster than the national service industry production index by 15.2 percentage points.

　　The development mentality of localities and enterprises is more "stable": "China’s economic strength potential is not what it used to be, and we have a lot of room for manoeuvre." "The international financial crisis 10 years ago came, but China bucked the trend and became the second largest economy in the world" … … In the interview, the reporter found that many local cadres and entrepreneurs are optimistic about the prospects of economic development, have a positive attitude towards some difficulties currently encountered, and their mentality is more calm.

　　"Only after being tested can you become an outstanding person. In the past 10 years, citic heavy industries has landed in the capital market, and has also provided supporting products and components for heavy equipment in countries such as shenzhou spaceship and C919. At present, the international market covers more than 40 countries and regions around the world." Talking about the development achievements in the past 10 years, Yu Zhangfa, chairman of citic heavy industries Machinery Co., Ltd., is a few treasures.

　　As one of the 156 key projects in China during the First Five-Year Plan period, citic heavy industries seized the opportunity to become a leader in the field of heavy equipment manufacturing in response to the international financial crisis.

　　"Aiming at high-quality development and opening up the international market, this is the stabilizer for development." Yu Zhangfa said that relying on the global layout, citic heavy industries is following up a number of overseas key complete sets of projects, main engine projects and spare parts service projects, and it is expected that the total number of effective overseas orders will increase in 2019.

　　Since the beginning of this year, China’s economy has achieved a smooth start under the pressure challenge, and it continues to play the role of "stabilizer" of the world economy, which has won praises from foreign media for its "stable and resilient chassis".

　　Where does stability come from?

　　Stable support comes from the positive factors that the policy effect continues to appear.

　　Quickly coordinate and solve enterprise problems in view of practical difficulties; Establish an "order tracking system for 91 key foreign trade enterprises" covering 65% of the province’s total import and export volume to track the fluctuation of import and export volume and price and employment impact; Introduce "22 measures" to optimize port business environment and promote cross-border trade facilitation … …

　　From January to May, Sichuan’s import and export to the United States increased by 13.7% year-on-year, and the export growth to ASEAN, the European Union, Japan and other overseas markets drove the province’s export growth by 30%.

　　Yang Ni, deputy director of the General Department of the Sichuan Provincial Department of Commerce, told the reporter that over the past year or so, enterprises have actively responded and struggled to transform, and the government has tried every means to create a good environment for enterprises, and achieved a good development trend with one heart and one mind.

　　This is a microcosm of China’s active response to challenges.

　　Since the beginning of this year, we have implemented a larger scale of tax reduction and fee reduction, made great efforts to ease the financing difficulties of enterprises, stabilized and expanded employment in a multi-pronged manner, and made efforts on the supply side to build a strong domestic market … … A series of pragmatic measures were introduced intensively, and macro-policies were adjusted countercyclically, which opened up growth space for China economy.

　　Stable support comes from the lasting power of kinetic energy to accelerate the conversion and release.

　　Surrounded by green mountains and green waters, we walked into the production workshop of Chongqing Wanguo Semiconductor Technology Co., Ltd., where chips were being manufactured, packaged and tested, and some products only needed to be transported for several kilometers to reach the target market. This American-owned enterprise is the second manufacturing, packaging and testing base of 12-inch power semiconductor chips in the world.

　　Qi Yuanlin, director of the company’s public relations department, told reporters that Chongqing’s complete and mature automobile and electronics industry system has provided a broad market space for enterprises.

　　"We will not give up the huge consumer market and the huge technical talent team here." Lei Guohui, general manager of ASM Pacific Technology Co., Ltd., a manufacturer of semiconductor integration and packaging equipment, said that they are preparing to build the fourth manufacturing base in China in Jiujiang, Jiangxi.

　　Although the economic market remains stable, we also feel that the uncertainty brought by the external environment persists, which affects the investment expectation and confidence of enterprises to some extent; Various cost factors have risen, and the operating pressure of the real economy is still relatively high; The differentiation of different regions and industries is still going on, and the conductivity of external influences cannot be underestimated; The implementation of various policies needs to be further strengthened.

　　"Sino-US economic and trade frictions have lasted for more than a year, and people’s understanding has become more and more objective, rational and comprehensive." Ning Jizhen, deputy director of the National Development and Reform Commission, said in an interview that the key is to maintain strategic strength, enhance confidence in winning, dare to take responsibility, be good at planning, and concentrate on doing your own thing well.

　　Where does China’s economic vitality come from? — — Contains a word "change"

　　"In the face of uncertainty, we should not only change with constancy, but also change with ‘ Change ’ Should change. " Yang Quanxing, general manager of Guangdong Textile Import and Export Co., Ltd. told reporters.

　　Breaking rigid thinking, thinking about change through reform, seeking change through transformation, and winning through change … … "Change" has become a distinctive feature of China’s economy and the vitality of China’s economy.

　　Change ideas, turn passivity into initiative, and strive to find opportunities in danger — —

　　"In the future, put on our smart clothes and download an APP, and it will become yours ‘ Personal coach ’ Teach you how to keep fit, dance and even practice yoga … …” Yang Quanxing described the company’s new products in the future.

　　Aiming at the Internet of Everything and the development trend of great health, this company began to develop smart clothes as early as a few years ago, and it is expected to be put into mass production soon.

　　"Opportunities are not waiting, but created." He said.

　　The reporter has a prominent feeling in the investigation. Faced with the difficulties in development, many entrepreneurs have a more peaceful mentality, and their "playing style" is also changing: from passively lowering prices in the past to actively developing new products, improving quality and improving efficiency.

　　There is thunder in the silence. When the wind is against the wind, it is often a good opportunity for those excellent enterprises to take advantage of their accumulated wealth and narrow the gap with their competitors.

　　At present, it is the best time for the development of emerging industries such as artificial intelligence, Internet of Things and 5G. Aiming at the development of 5G and laying out the whole industrial chain of optical fiber communication in advance, Fortis Group, which is one of the top 500 Chinese enterprises, is now welcoming a new "window" in its pursuit of innovation and change.

　　This is the optical communication intelligent manufacturing R&D center of Futong Group (Jiashan) located in Jiaxing, Zhejiang Province (photo taken on June 1, 2017). Xinhua News Agency reporter Zhang Yushe

　　"With the official issuance of 5G commercial licenses in China, the demand for optical fibers and cables will be three to five times that of the 4G era." Wang Jianwei, Chairman of the Board of Directors of Fortis Group, said that they will actively integrate into the national development strategy through a new round of transformation, upgrading and innovative practice, and make positive efforts for the construction of 5G networks and the development of national informatization.

　　Seek change in vision, aim at a broader space and open up a broader market — —

　　On one side of the factory building, aircraft parts are being pre-assembled, and the assembly machine is busy; In the factory building on the other side, exquisite planes spread their wings and wait to fly … … This is a scene of CLP Wuhu diamond aircraft Manufacturing Co., Ltd..

　　"Wuhu is a can ‘ Make something out of nothing ’ As long as you have a broad vision, you can fly out of a new world. " Hong Yuning, the general manager of the company, said that the company has gradually formed a complete general aviation industry chain from technology introduction to independent research and development, which has also enabled Wuhu aviation industry to grow from scratch.

　　General aviation refers to all civil aviation except regular airline flights used for passenger and cargo transportation, with huge development space. At present, this industrial chain is driving the rapid development of the entire industrial chain such as aircraft R&D and manufacturing in Wuhu City and even Anhui Province.

　　As soon as the train of thought changes, the world becomes wider.

　　Hunchun, Jilin, is not near the sea. Hunchun tried every means to "borrow a port to go to sea", and opened a land-sea combined transport route with Hunchun as the frontier and facing Northeast Asia-zarubino in Russia-Busan in South Korea. There is no port in Hunchun, thus creating a well-known "seafood city".

　　In the investigation, the reporter found that in the face of practical difficulties, more and more localities and enterprises pay attention to adjusting their thinking and strategies, promoting diversified market development and seizing the initiative.

　　For Zhejiang dabelin valve co., ltd, building its own brand and developing diversified markets are two cards for enterprises to cope with external challenges.

　　"Eggs can’t all be put in one basket. At present, our business has spread to about 130 countries and regions around the world, and we have confidence in coping with external risks." Lin Hailin, chairman of the company, said.

　　Change the mechanism, do everything possible to create conditions, and seek development wholeheartedly — —

　　South Yangtze River Delta: The Yangtze River Delta integration strategy has been further promoted. Recently, 86 major regional integration cooperation projects have been signed among nine cities including Shanghai Songjiang, Jiangsu Suzhou, Zhejiang Hangzhou and Anhui Hefei, with a total investment of 219.2 billion yuan … … Innovative resources are constantly accumulating and forming a joint force in cross-regional flows.

　　From Xiong ‘an to Pudong and then to Shenzhen, from the coordinated development of Beijing-Tianjin-Hebei to the construction of Guangdong-Hong Kong-Macao Greater Bay Area and then to the regional integration of the Yangtze River Delta, from the east to the rise of the central region, the revitalization of the northeast and the development of the west … … The coordinated development of "communities" across administrative regions has been accelerating, the spatial layout of reform and opening up has been accelerated, and the pace of high-quality development has become more solid.

　　What is the economic prospect of China? — — Understanding a "new" word

　　"Under the situation of increasing global instability and uncertainties, China’s economic growth remains resilient." In the latest issue of China Economic Bulletin, the World Bank commented on this.

　　What is the password for China’s economy to successfully hedge the uncertainty of external environment and develop with each passing day?

　　Hedge with the certainty of innovation and continuously cultivate new economic kinetic energy — —

　　From the New Bay Bridge in the United States to the canakkale Bridge in Turkey, the cables developed and manufactured by Aosheng Group have been adopted by many landmark large bridges in the world.

　　Since the beginning of this year, the cable business of Aosheng Group in Shanghai has received sufficient orders, and the factory has worked overtime. "After more than 20 years of innovation and development, we have won 13 major scientific and technological achievements, including the first prize of national scientific and technological achievements, and have 123 invention patents. Leading technology and reliable quality are the core competitiveness!" Tang Liang, chairman of Aosheng Group, said.

　　Get rid of illusions and speed up innovation.

　　In the investigation, the reporter found that the awareness of the government and enterprises from "I want to innovate" to "I want to innovate" is more prominent, and the consensus that "seeking innovation means seeking the future" is more cohesive.

　　Walking in the core area of Yuehai Street in Nanshan District, Shenzhen, you can feel China’s "heavy" economic weight and "active" innovation power. Many well-known technology companies, such as Tencent and DJI, gather in high density in an area of less than 15 square kilometers. Now there are 156 listed companies in Nanshan District, where the GDP last year exceeded 500 billion yuan … …

　　"Strong innovation ability is not only a powerful driving force for development, but also the only ability to determine the survival of an enterprise, and it is the only law that has been repeatedly proved by practice." A department head of Huawei is so emotional.

　　With an average of 51 invention patents granted every day, Shenzhen, with the title of "Innovation Capital", has become a vivid footnote in the grand chapter of China’s economic transformation and upgrading, driven by innovation that attracts global attention.

　　The total number of R&D personnel ranks first in the world, and the ranking of "2018 Global Innovation Index" rises to 17th. The number of invention patent applications and authorizations ranks first in the world, and the contribution rate of new kinetic energy to China’s economic growth exceeds one third … … In today’s China, innovation and development are becoming a trend.

　　With unremitting innovation, China’s economy is full of natural kinetic energy!

　　In the first five months of this year, the country added a total of 893 billion yuan in tax reduction and fee reduction, and a series of tax reduction and fee reduction policies, such as deepening the reform of value-added tax and individual tax, gradually became effective.

　　New data shows new dividends. This year, it is estimated that the tax reduction and fee reduction of 2 trillion yuan will be unprecedented. This is just a window to observe China’s strong push for reform.

　　Develop a topic and make a fuss about reform.

　　Starting this year, the "project manager" system in Liaoning Province will cover all enterprises above designated size and key projects. "It is to do nothing and be responsive." As the "housekeeper" of Tencent, Huawei and Liaoning, He Qing, director of the Liaoning Provincial Department of Industry and Information Technology, described his work.

　　From striving for investment and preferential policies to striving for service and business environment, local governments have carried out healthy competition with new reform measures, highlighting the clear path for China’s economy to achieve high-quality development.

　　In January this year, Chengdu took the lead in setting up the first new economic development committee in China, dedicated to creating an institutional environment conducive to the development of the new economy. In Zhongguancun Chuangye Street, the pilot reform of providing the registered address of enterprises free of charge and implementing "cluster registration" has solved the problem of finding business premises for start-ups; In Shanghai, focus on "one network to run" and get rid of the "pain points" and "difficulties" of enterprises and the masses … …

　　Remove market access barriers to the maximum extent, speed up the reform of state-owned enterprises, fiscal and taxation, land system and other important areas and key links, reduce the number of industrial production license by more than half, and cancel the decentralization of more than 50 administrative licenses at the central level to create a "one network" of national government services … …

　　Determined to reform, China is on a roll!

　　Hedge with openness and certainty, and actively build a new pattern of development — —

　　Recently, Pfizer’s global headquarters was unveiled in Shanghai, which is the first time that a multinational pharmaceutical company has set up a global headquarters in China. In the first four months, Shanghai’s newly established foreign investment projects, contracted foreign investment and paid-in foreign investment all increased by more than 20% year-on-year, and continued to become a hot spot for global investment.

　　In the first five months of this year, China actually used 369.06 billion yuan of foreign capital, up 6.8% year-on-year, and foreign companies cast a "vote of confidence" in China’s economy.

　　Since the beginning of this year, in the face of the counter-current of economic globalization, from greatly relaxing market access to strengthening intellectual property protection, from expanding the Pilot Free Trade Zone to introducing a foreign investment law, China’s actions have confirmed its determination to open up.

　　On the last day of the first half of the year, China issued a new version of the negative list of foreign investment access, and continued to compress the contents of the list, so that foreign investors will invest in more fields; Introduce the 2019 edition of the catalogue of industries that encourage foreign investment and expand the industries and fields that encourage foreign investment.

　　With the continuous opening up, China’s development will naturally have a big pattern!

　　"Despite many external unfavorable factors such as the deterioration of international trade conditions, China has maintained a steady growth trend through a series of measures such as tax reduction and fee reduction and opening up." Mao Xuxin, chief economist of the National Economic and Social Research Institute, said.

　　Avenue to Jane. After reading China’s determination and actions of innovation, reform and opening-up, we can find the code for China’s economy to move forward steadily without fear of wind and rain. (Reporter Zhang Xudong, Zhao Chao, An Bei, Yu Jiaxin, Chen Weiwei, Jiang Lin)

"knowing that it is impossible for you to leave his world, I am still silly to wait until the day when the miracle occurs, until that day.
You will find that the person who really loves you is alone in mourning … "Whenever a familiar melody rings, there will always be a person in my mind, and that is him. When he was a hit, he was even more popular than Dao Lang at that time. His song has been sung for more than ten years. However, the love song prince was born out of wedlock at the age of 40, and his image plummeted. Now A Mei, who is down and out, pities him. He is Li Shengjie.

Around 2004, popular songs were rampant in the Chinese music scene, and a large number of pop singers emerged. Up to now, their songs are also widely sung. For example, Tang Lei’s Lilacs, Dao Lang’s The First Snow in 2002, Pang Long’s Two Butterflies, Yang Chengang’s Mice Love Rice, Vowing to Pray for Buddha, Wang Qiang’s Don’t Come Back in Autumn, etc., and he also made his debut at this time.

He was born in Bay Bay, and he loved music since childhood. He was also trained by a professional singing teacher. In 1997, on the variety show "Super Newcomer King", he relied on an "I"
Swear won the championship and began to debut.

Later, with the advice and help of Bao Bida, he released his first album "Cold Coffee" in 1999, but his music career was bleak because of publicity problems. After a few years of silence, he returned to the earth in 2002, and released the album "Infatuation Absolute". The title song of "Infatuation Absolute" was also a hit, which was popular all over the Taiwan Straits and was sung in the streets, and he also ushered in the peak of his career.

Then, while the iron was hot, an album "Absolute Infatuation Let Go of Hands" was released, and a song "Let Go of Hands" became popular all over the country again. At that time, he appeared in Shang Yan with these two songs, and even overshadowed the then popular Dao Lang. A song "infatuation is absolute" has been popular for 15 years, during which he sang it 8000 times himself.

However, after 2009, he gradually faded out of everyone’s sight. It was not until 2013 that it was reported by the media that the love song prince was unmarried and had children, which caused his reputation to be damaged and the scenery was no longer there.

Last year’s
At that time, he appeared at the scene of "The Voice of Dreams", which immediately aroused the whole audience’s nostalgia. He also had deep feelings with the on-site tutor, but now he can only go down to the acupuncture point, which also caused A Mei to cry, only pity.

　　He used to be a love song prince. I hope he can cheer up and bring us more extraordinary works.

For 35 years, he devoted himself to the seismic research and teaching of building structures, and a new structural seismic technology was born from him and his team. He is actively committed to applying the latest seismic research results to engineering practice and escorting a number of major projects in China; He insisted on the road of international cooperation in seismic research and led the team to push China’s structural seismic research to the international stage …

He is Professor Lv Xilin, a newly-elected academician of China Academy of Engineering and an expert on earthquake resistance of building structures in Tongji University School of Civil Engineering. In November 2015, he won the "Science and Technology Progress Award" in ho leung ho lee foundation. In February 2017, he was awarded the Newmark Award by the American Society of Civil Engineers.　　

Determined to do seismic research of buildings

This is a scene of the disaster area three days after the Wenchuan earthquake.

Here is a unit building in Qingchuan County, which was seriously affected by the disaster. The building is covered with numerous cracks. A burly middle-aged man is fearless, and the cat is the first to get in, looking at the damaged structure everywhere.

He is Professor Lv Xilin, the head of the expert group of Tongji University, the first batch of housing emergency assessment in Wenchuan earthquake-stricken areas of the Ministry of Housing and Urban-Rural Development. He volunteered at the first time after the disaster and rushed to the front line of earthquake relief.

Looking back more than 40 years ago, in 1976, when the Tangshan earthquake occurred, he was a sophomore in Xi ‘an Institute of Metallurgy and Architecture (now Xi ‘an University of Architecture and Technology), majoring in "Industrial and Civil Architecture". At that time, Xi’ an also had an obvious earthquake. "The earthquake caused so many houses to collapse in an instant and took so many living lives, which touched my heart very much." Lv Xilin recalled, "From then on, I was determined to go to graduate school and concentrate on seismic research of buildings."

After graduating from college, he wished to enter Tongji University, which has the highest strength in earthquake resistance in civil engineering in China, to study for a master’s degree in structural engineering. In March, 1982, he continued to study for a doctorate in structural engineering at Tongji University, under the guidance of Professor Zhu Bolong, a well-known expert from Tongji University. The topic of his thesis is the seismic research on a large number of masonry structures in China. He also became the first batch of doctoral students after China resumed the postgraduate enrollment system.

In December 1984, Lv Xilin successfully passed the defense of doctoral thesis and became the first doctoral student in structural engineering in Tongji University.

"There are still many unsolved problems in the field of building earthquake resistance, and there are still many unknown phenomena waiting for us to explore." Young Lv Xilin, with the enthusiasm of scientific exploration, embarked on the journey of seismic research of building structures.　

Play a good job in the new technology of structural earthquake resistance "combination boxing"

This is a building in Dujiangyan. In the middle of the first and second floors, a structural member with a length of about one meter can show its talents when a strong earthquake strikes. It absorbs and consumes the energy released by the earthquake, so that it no longer strongly impacts the house; Its seismic fortification intensity is increased from 7 degrees to 8 degrees. This is a new type of structural seismic device-"damper" installed on the H-shaped steel support, which comes from Lv Xilin’s team and has been widely used in the restoration and reconstruction project of Wenchuan earthquake-stricken area, the seismic safety project of national school buildings, and other important projects such as Shanghai Ganghui Square.

"Traditional reinforcement is generally to thicken the beams and columns of the building, which not only has a long construction period and high cost, but also shrinks the housing area." Professor Lv Xilin said that the adoption of new brace+damper technology not only greatly improved the seismic capacity of buildings, but also saved a lot of engineering time and cost.

In fact, the team played the "combination boxing" of structural earthquake resistance: "rubber bearing+sliding bearing+viscous damper". The "isolation bearing" is installed between the building foundation and the foundation. When the earthquake occurs, the bearing shakes, dissipates energy and reduces vibration, while the building on it is motionless, so it is soft and rigid. The flexible and innovative combined isolation and vibration reduction system has been successfully applied to major projects of Shanghai International Circuit and more than ten foreign construction projects.

He insisted that the research results should be closely combined with the actual project: "We are not seeking technology for technology’s sake, but we should fully consider how to make the seismic structure system more reasonable and safer, the construction easier and the project cost lower."

Team Lv Xilin pays close attention to the safety of complex high-rise buildings. Most of these over-code high-rise buildings are particularly complex in shape, changeable in internal space and ever-changing in structure, which poses great seismic challenges to their structures. Over the past 20 years, Professor Lv Xilin led the team to continue in-depth research and made new breakthroughs in the theories and methods related to seismic analysis and design of complex high-rise buildings. The results have been applied to the seismic design and performance evaluation of more than 50 major or key projects in China, such as Shanghai Tower and Shanghai World Financial Center.

The team’s technical achievement of "one lifting, two moving and three strengthening" to improve the seismic performance of existing buildings has also been successfully applied to the relocation and reconstruction of outstanding historical buildings such as Shanghai Concert Hall and Shanghai Jade Buddha Temple Daxiong Hall.

He often teaches students: "Don’t be bound by the existing seismic technology of structures, or even be bound and restricted by the existing codes." For more than 30 years, he led the team, constantly exploring, developing and breaking through the existing seismic technology of building structures, and won the second prize of national scientific and technological progress and the second prize of national technological invention …

As early as more than ten years ago, he began to pay attention to and introduced the concept of "recoverable earthquake-proof structure" for the first time in China. Since then, he has led the team to invest a lot of time in tackling key problems, and the results have attracted the attention of international peers.

"Teacher Lu’s high sensitivity to the new structural seismic technology, his accurate grasp of its future development direction, and his tenacious spirit of persisting in the identified fields all make our students admire and feel ashamed." His student Professor Li Peizhen lamented this.

In tackling key problems in scientific research, Lv Xilin never forgets to teach and guide students. "Earthquake resistance and disaster prevention is a public welfare undertaking, and we must have dedication." "The engineering anti-seismic technology is regional, and we must develop new technologies in combination with China’s actual situation." In recent years, many doctoral students he trained and supervised chose to work in Xinjiang, Northwest China, Southwest China and Northeast China when they graduated.　

Promote international cooperation in the field of earthquake engineering

Walking in Building B of the Civil Building where the Department of Structural Disaster Prevention and Mitigation Engineering is located, you can often see young students from abroad exchange and study here.

In April this year, Tongji University Joint Laboratory for International Cooperation in Earthquake Engineering successfully passed the acceptance demonstration organized by the Ministry of Education, and experts recognized its construction achievements.

In July 2015, the "Joint Laboratory for International Cooperation in Earthquake Engineering" was established in Tongji University, bringing together the strengths of China, the United States, Japan and Italy to jointly carry out research on major international frontier earthquake-resistant scientific issues. Lv Xilin is the director of the Academic Committee of the Joint Laboratory, which is also the fruit of his decades-long adherence to the road of international cooperation.

The internationalization characteristics of Tongji academic had a deep understanding during Lv Xilin’s study in Tongji Garden.

After staying in school after graduation, Lv Xilin took the initiative to go out and keep in close contact with international colleagues. Tokyo institute of technology, University of California, Berkeley, Italian European Earthquake Engineering Research Center and other internationally renowned earthquake engineering research centers have all formed friendly cooperation partners with him.

After the Wenchuan earthquake, Lv Xilin established the Guanghua Academic Forum in the field of earthquake engineering. In the past 10 years, the forum has been held for 8 times, and a group of colleagues from the field of earthquake engineering at home and abroad gathered in Tongji for each session to exchange the latest research progress.

In September 2011, Lv Xilin became the new editor-in-chief of the international academic journal "The Structural Design of Tall and Special Buildings". This is the first time that a China scholar has been the editor-in-chief of the magazine since it was founded more than 20 years ago. In 2017, he was awarded the Newmark Award by the American Society of Civil Engineers. Established in 1975, this prize is awarded once a year, and each time a scientist who has made outstanding contributions in the field of structural engineering and engineering mechanics is selected worldwide. Lv Xilin is the first China scholar to receive this honor.

He also actively encourages and subsidizes postgraduate students and doctoral students to boldly make presentations at international forums. His doctoral supervisor, Professor Ying Zhou from Tongji University School of Civil Engineering, felt deeply "benefited from this". During his doctoral studies, Ying Zhou had the opportunity to give an academic report in international forums. After staying in school, she went to Berkeley to carry out project cooperation, and grew up all the way on the academic road. Now she has become the vice chairman of the International Society for Disaster Reduction and Control, the winner of the National Natural Science Foundation’s outstanding youth fund, and the director of the structural disaster prevention and mitigation engineering department of Tongji University.

"We can proudly say that the scientific and technological level of earthquake resistance and disaster reduction in China has been ranked among the first corps after the United States and Japan, and the gap is narrowing. We are mainly lacking in the fineness of product manufacturing and earthquake research." Professor Lv Xilin said that the International Joint Laboratory focused on civil and infrastructure projects, major construction projects, long and long bridge structures, lifeline projects, long and long tunnel structures, deep-water foundations and large-scale energy facilities that can recover their functions after the earthquake. In the past three years, it has released 14 research topics to the world, and achieved results in discipline construction, talent training and introduction, international cooperation and collaborative innovation.

"Structural earthquake prevention and disaster reduction, there are still many things to do. I will stick to my original heart and continue to go in the direction we are looking for with the team. " Looking to the future, he is still full of confidence. (Ai Jiao)
