多维邻近性对技术创新合作绩效的影响效应——以长江中游城市群合作网络为例

The Effect of Multidimensional Proximity on Technology Innovation Cooperation Performance:Taking the Middle Reaches of Yangtze River Urban Agglomeration Cooperation Network as an Example

围绕长江中游城市群技术创新合作网络结构特征与影响因素两个关键研究问题,以专利文献这一重要技术信息数据源为基础,提出一套系统可行的城市群技术创新合作网络分析模型。研究发现,长江中游城市群技术创新合作网络整体呈现为省内合作关系强、省际合作较弱;区域内“中间人”较缺失,阻碍了知识信息资金等传播的效能,降低了合作意愿;地理邻近性与技术创新合作绩效呈倒“U”型关系,且正处于上升态势,能够正向促进技术创新合作网络的发展;地理邻近性与制度邻近性的交互作用正向促进技术创新合作绩效,且二者交互作用大于其独立作用。

This paper focuses on two key research issues:structural characteristics and influencing factors of technology innovation cooperation network in the middle reaches of Yangtze River urban agglomeration.This paper proposes a comprehensive and systematic analysis model of technology innovation cooperation networks in urban agglomeration by using patents as the data source.The results show that:the technology innovation cooperation network in the middle reaches of Yangtze River urban agglomeration shows the characteristics of intra-provincial solid cooperation relationship and weak inter-provincial cooperation.The lack of intermediaries in the region hinders the efficacy of knowledge,information,fund,and other dissemination and reduces the willingness to cooperate.The geographical proximity has an inverted U-shaped relationship with the performance of the technology innovation cooperation network and is on the rise,positively promoting innovation cooperation.The interaction between geographical proximity and institutional proximity positively promotes the performance of technology innovation cooperative network,and the interaction between them is more significant than their independent effects separately.
