Abstract:Based on the characteristics of "network organization" of industrial innovation ecosystem, this paper studies the structure of industrial innovation ecosystem from two dimensions: system components and system relationships. According to the empirical analysis on innovation ecosystem of new energy vehicle industry in Liaoning province, we find that the industrial innovation ecosystem structure of new energy vehicle industry in Liaoning province is not balanced. Innovation consumer populations mainly with vehicle manufacturing enterprises and auto parts enterprises occupy the dominant position, while innovation producer populations, decomposer populations and innovation survival factors are obviously on the edge of the ecosystem. Innovation populations have not yet formed closed communities, as well as the efficiency of technology flows is insufficient. As the role of , the leading companies in the regional industries occupy the important position of hole structures, and have a high level of integration and media. The reciprocity between knowledge chain network,industrial chain network,geographical proximity network and industrial innovation ecosystem is strong. However, there is an inhibition between knowledge chain network and industrial chain network in a certain extent. Based on conclusions above, some suggestions are put forward.
