Abstract: City has become the center of innovation because of its many advantages relative to village. City network is helpful to arouse city’s ability in technological innovation according to the formation of innovation networks, knowledge flow among innovators, innovation diffusion mode and efficiency. This paper measures the global features and individual characters of city network by using methods of complex social network based on airline flow data between Chinese cities. Then effects of city network on technological innovation are analyzed. Results show that expansion of city network’s absolute density and enhancement of cities’ connection can promote the level of technological innovation. Strong links between cities affect knowledge flow and facilitate technological innovation. The centricity of city network determines the distribution of connection and affects innovation diffusion and knowledge flow within network. Higher degree centrality city has higher potential for innovation. Higher betweenness centrality city has strong control force in knowledge and innovation diffusion. In the end, some conclusions and suggestions are put forward.
