长三角城市群创新网络结构及其驱动因素研究

Research on Innovation Network Structure and Driving Factors of the Yangtze River Delta Urban Agglomeration

基于创新网络视角,采用社会网络分析法（SNA）对2007—2016年长三角城市群创新网络的空间结构演化及其驱动因素进行实证分析。研究表明：长三角城市创新网络处于动态演化中,逐渐形成“核心-次核心-边缘”的稳定态势;网络整体联系愈加紧密,但子群间的关联强度存在显著差异;产业结构、高校人数、科技支出、地理邻近性是城市创新网络的重要驱动因素。最后,从资源整合、横向协同等方面提出了推动城市创新网络良性发展的若干建议。

Based on the perspective of innovation network, this research empirically analyzes the spatial structure evolution and driving factors of the innovation network of 2007-2016 Yangtze Delta urban agglomeration by utilizing Social Network Analysis （SNA） method. The research proves that the Yangtze River Delta urban innovation network is in the dynamic evolution, and gradually forms the ＂core-subcore-edge＂ steady trend; the overall connection of the innovation network is closer, but the correlation strength between sub-groups is significantly different; industrial structure, the number of colleges, science and technology expenditures, and geographic proximity are key factors influencing urban innovation networks. Finally, from the perspective of resource integration and horizontal coordination, some countermeasures and suggestions for promoting the benign development of urban innovation networks are put forward.
