In recent years, focusing on building a national important advanced manufacturing highland, Hunan has made every effort to grasp 22 emerging advantageous industrial chains (clusters). At present, Hunan Province has 22 national single champion enterprises and products in the manufacturing industry, 232 "little giant" enterprises specializing in special new products, and all kinds of factor resources are accelerating the flow to the manufacturing field. On October 25, the world's largest tower crane w12000-450 went offline at Zoomlion tower crane intelligent factory in Changde, Hunan Province. This product is specially built by Zoomlion for Changtai Yangtze River Bridge, the world's largest span highway railway dual-purpose cable-stayed bridge under construction. The maximum lifting weight is 450 tons and the maximum lifting height is 400 meters, which is equivalent to lifting 300 cars to 130 floors at one time. Three days later, on October 28, Sany scc9800tm crawler crane, the world's largest tonnage crawler crane produced by Sany Heavy Industry, was successfully delivered in Zhejiang. This is by far the crawler crane with the largest lifting torque in the world, and it is also one of the most technologically advanced and system integrated products in construction machinery products. Behind the heavy weapons of a big country is the rapid development of Hunan's advanced manufacturing industry. At the beginning of this year, the Ministry of industry and information technology announced 25 national advanced manufacturing clusters, and Changsha construction machinery and Zhuzhou rail transit equipment were selected. In the first half of this year, the output value of Changsha construction machinery industry cluster was 135.236 billion yuan, a year-on-year increase of 29.04%. There are more than 400 enterprises in Zhuzhou rail transit equipment industry chain. From January to July this year, the output value of the cluster increased by 14.1%. In recent years, focusing on building an important advanced manufacturing highland in China, Hunan has made every effort to grasp 22 manufacturing industry chains (clusters), improve the value chain, deploy the innovation chain and improve the capital chain around the industrial chain, and accelerate the flow of various factor resources to the manufacturing field. At present, Hunan Province has 22 national single champion enterprises and products in manufacturing industry, and 232 "little giant" enterprises specializing in special new products. Strengthen technology R & D and build an emerging industrial chain In the national intelligent networked automobile (Changsha) test area of Xiangjiang new area, the reporter took the self driving electric vehicle and started, turned and braked. The L3 level intelligent driving was extremely stable. "For the closed test park covering an area of more than 1000 mu, the enterprise test has been scheduled to the end of this year," said Xie Guofu, chairman of Xiangjiang intelligent company. Intelligent networked automobile is a future industry planned and distributed in advance in Changsha and even Hunan. According to the "integration of vehicle, road and cloud network", Changsha has actively created various application scenarios and completed the construction of 100 square kilometers of urban intelligent network open road area, 100 kilometers of smart Expressway and 7.8 kilometers of smart bus demonstration line. Changsha accelerated the integration of intelligent connected vehicles and intelligent transportation, transformed the first mover advantage into industrial advantage, attracted more than 20 industry leaders and more than 340 supporting enterprises to settle down, and built an intelligent connected vehicle industry ecological cluster in an all-round way. In the journey of building an advanced manufacturing highland, on the one hand, Hunan has consolidated its traditional advantageous industries, on the other hand, it has selected 22 emerging advantageous industrial chains (clusters) such as construction machinery, advanced rail transit equipment, information technology application innovation, advanced ceramic materials, carbon based materials, new energy and intelligent networked vehicles, artificial intelligence and sensors, As the focus of promoting the high-quality development of manufacturing industry. The reporter learned that around 22 industrial chains (clusters), Hunan has integrated the province's scientific and technological advantages, arranged a number of key scientific and technological research projects, supported the solution of industry difficulties, and implemented the "top ten technological research projects" and major scientific and technological projects. At present, breakthroughs have been made in a number of key technologies such as high-speed maglev transportation system with a speed of more than 600 kilometers per hour, main bearings of railway construction heavy industry and underground engineering equipment. In addition, Hunan has also implemented 128 strong foundation projects for product innovation, developed a batch of core basic parts such as construction machinery gland, a batch of advanced basic processes such as the recycling of highly doped waste broken glass, a batch of industrial basic technologies such as high-speed, high-precision intelligent multi-wire cutting, and a batch of industrial basic software such as "one cloud, multi-core" cloud desktop. Establish "enterprise chain leader" to promote cluster development It is a busy scene in the production workshop of Zoomlion intelligent aerial work machinery company in Wangcheng, Changsha. The high-altitude operation mechanical equipment produced by the company applies modern sensing technology and Internet of things technology, and is equipped with the "brain" of artificial intelligence, which can realize intelligent fault alarm diagnosis and provide safety early warning. Zoomlion is a leading enterprise in Hunan Construction machinery industry chain. There are more than 400 supporting enterprises in Hunan around Zoomlion. In order to realize the benign interaction and breakthrough development of the industrial chain, Zoomlion cooperates with upstream and downstream enterprises to tackle key technical problems. Such industrial chain linkage originates from the "enterprise chain length" system established in Hunan. Including Sany Heavy Industry, Zoomlion, Shanhe intelligent, railway construction heavy industry, etc., in recent years, some industry leading enterprises in Hunan Province are not only accelerating their own innovation and development, but also driving the development of enterprises related to the industrial chain. On August 21, during the construction of the reconstruction project of Beijing East Sixth Ring Road, the "Jinghua" shield machine with a diameter of more than 12m independently developed by China railway construction heavy industry successfully crossed the first level risk source and won the first battle. Among them, the cemented carbide shield cutter head, the key core component of the "Jinghua" shield machine, was developed by China railway construction heavy industry in conjunction with Central South University and Hunan Boyun Dongfang Powder Metallurgy Co., Ltd. Around the research and manufacturing of roadheader cutters and track milling cutters, the three units promoted the autonomy and localization of key materials and core components. Increase rescue efforts and improve the quality and efficiency of enterprises Riye electric, a manufacturing enterprise in Changsha, has expanded rapidly and has many orders in recent years. At the beginning of this year, in the face of huge orders, the enterprise's cash flow was urgent. After learning about the capital needs of the enterprise, the Bank of Changsha issued a working capital loan of 10 million yuan for it in less than 10 days. "Thanks to the government's inclusion of us in the 'white list', the bank provides timely assistance," said Gong Jian, general manager. The financing difficulties of manufacturing enterprises have existed for a long time. In Hunan, by setting up a "white list" and guiding financial institutions to implement differentiated credit policies, manufacturing enterprises have obtained loans of more than 100 billion yuan. In addition, Hunan also initiated the "one chain, one line" host bank mechanism to help enterprises solve financing pain points, and the financing demand of more than 70 billion yuan has been settled. In the first three quarters of this year, Hunan's manufacturing loans increased by 39.27 billion yuan, an increase of 2.58 billion yuan year-on-year. In order to further strengthen the support for manufacturing enterprises, Hunan has also formulated a work plan for provincial leaders to contact industrial clusters (industrial chains) to promote the construction of national important and advanced manufacturing highlands. The main leaders of the provincial Party committee serve as the industrial chain leader of construction machinery, and the main principals of the provincial government serve as the industrial chain leader of advanced rail transit equipment. With the help of various parties, in the first half of this year, the manufacturing tax revenue of Hunan Province increased by 19.9% and the manufacturing profit increased by 30.3%; The output of computers, integrated circuits, lithium-ion batteries and optoelectronic devices increased by 1.5 times, 1.6 times, 65.6% and 36.8% respectively. Mao Tengfei, director of Hunan Provincial Department of industry and information technology, said that Hunan will build an important national advanced manufacturing highland with the industrial chain (Group) as the starting point. By 2025, it will achieve the "1125" goal of high-quality development of advanced manufacturing industry, that is, improve the innovation carrying capacity of 100 parks, develop 1000 major technological innovation products, cultivate 20 100 billion industries and 5 trillion industries.
