Research On The Innovation And Cooperation Network Of Automobile Industry In The Yangtze River Economic Belt

Under the background of economic globalization, the role of innovation in knowledge economy is becoming more and more significant. Regional innovation network has become one of the hot issues in the study of economic geography and management. In the industrial 4.0, "Made in China 2025", a new round of revolution of science and technology, the industrial revolution and the rapid development of economy, the automobile industry as one of key areas of manufacturing industry in China, how to improve the independent innovation, own brand bigger and stronger, to achieve industrial upgrading is an urgent task for the automobile industry. In the context of industries transfer to actively promote the eastern region to the central and western region, the Yangtze River economic belt has the role of linking east and west. Under the guidance of innovation driven development strategy, cooperative innovation has become an important way to realize the green, coordinated and sustainable development of the Yangtze River Economic belt. Therefore, the in-depth analysis of the Yangtze River Economic Belt innovation networking environment, the study of the Yangtze River Economic Belt automobile industry innovation collaboration network development has important theoretical and practical significance.The joint-patent application is a kind of widely used empirical indicators,mainly reflects knowledge diffusion betweenorganizationsbased on cooperative innovation. And cooperative patent application can reflect the more important of knowledge innovation in the sharing and transfer activities. Automotive industry involves a variety of technical areas, is the most typical of knowledge innovation industry, more in the form of patent applications to protect intellectual property rights. Some scholars suggest that automobile industry innovation cooperation occurs in the same city or between adjacent cities. The prefecture level city is taken as the basic spatial unit, the articlein-depth study formation and evolution of the automobile industry cooperative innovation network in the Yangtse River Economic Belt with 110 prefecture level citys. On the basis on the study of innovation networks, using social network and space network method, research and the exploration of the Yangtze River Economic Belt automobile industry innovation collaboration network for innovation and networking environment. From the perspective of network formation and evolution, the development stage of the innovation and cooperation network of the Yangtze River economic belt is divided, and the internal mechanism of the development of the automobile industry is analyzed. The cooperative relationship between different organizations and spatial scales, and the network evolution and structure of the network are analyzed. At the same time, taking Shanghai Automobile Group Co., Ltd as an example, the status of automobile enterprises in innovation network is further analyzed.The paper select related economic indicators, patents for inventionsdata of the Yangtze River Economic Belt automobile industry, quantitative analysis network scale, network center and intermediary network indicatorsby UCINET software and ArcGIS software, to further explore the innovation network evolution and structural characteristics, analysisthe position of the subjects in the network. Research shows that:innovation network of automobile industry in the Yangtze River Economic Belthas a good network and innovation environment; enterprises, universities and research institutions is the main subject of enterprise cooperation; enterprises gradually occupy an important position in the network; the cooperation between enterprises is significantly higher than that of other subject cooperation. The network began to multipolar transformation, citiesfrom the central and western regions gradually become network center. Network openness is stronger, position difference of th cities in the network isincreasing. Innovation network through joint venture joint ventureand private comprehensive development of early pregnant, to the era of globalization, promoting regional innovation cooperation in the Yangtze River Economic Belt. Compared with the United States, Japan, Germany auto industry innovation network, the automobile industry in the Yangtze River economic belt started late, the innovation network is still not perfect. There are still some gapsin theinnovation network structure and elements of composition, especially in the lack of independent innovation ability, and lack of cooperation with universities and research institutions.
