Abstract:In recent years, the development of the global auto market shows an overall situation of fluctuation and conversion of strong and weak. As a development trend of auto industry, the development of electric vehicles is ushered in the unprecedented new opportunity. In general the development of electric vehicles is gradually close to the original development expectations, especially the breakthroughs on some key technologies. There is no denying that developing the electric car is a fulcrum for the future development of the global auto industry. A bunch of companies has shown good development momentum in the innovation network organization of electric car, and has achieved certain progress. In this situation of the tripartite confrontation of the strong, Tesla——an electric cars corporation of the United States——goes into the public view and successes with its electric car Model S .This article analyzes the structure and the main features of innovation network from the perspective of knowledge sharing orientation. And based on the analytical investigation of the characteristics of the electric car innovation network and the characteristics of knowledge sharing among the electric car industry, the research conclusion of evolution and development of the innovation network of electric cars and the characteristics of each elements in the network organization will provide new perspectives to the development of the cooperation innovation and network structure theory.
