Empirical Study on Electric Vehicle Technology Transfer Network and Its Social Capital

The overall structure, individual characteristics, and the links among group members of technology transfer network have an important influence on the sustainable development of the network. Based on social network analysis approach, an empirical study on the structure of Electric Vehicle Technology Transfer Network(EVTTN)and social capital which arises from its characteristics is conducted. First, the nodes which represent the organizations involved in the technology transferring are identified, based on which the EVTTN at a certain time is constructed. Moreover, the structure of the network from the overall network structure(focusing on small world effect and small group)and individual attributes (focusing on central degree and the intermediary) are analyzed. Besides that, leading opinion and social capital among the network are judged, in order to provide a basis for the government management of the technology transfer market and the improvement of the robustness of the network.
