合作网络、预算投入与创新绩效——基于长三角41个城市间科技合作的证据

Collaborative networks, budget input, and innovation performance-- Evidence from 41 cities in the Yangtze River Delta

摘要:

为打开合作网络如何影响个体绩效的“黑箱”,本文根据合作网络(collaborative network)和资源基础观(resource-based view)相关理论,提出了“网络-预算-绩效”的传导机制,并搜集了长三角41个城市2011年至2020年科技合作网络数据,利用社会网络分析和面板数据回归分析检验了相关假设。实证结果表明：(1)在自组织城际科技合作网络中,城市的合作关系越多、关系越密切,城市的科技创新绩效越高；(2)科技预算支出发挥了重要的中介作用,科技合作网络提高了城市的科技预算支出,进而提高了其科技创新绩效；(3)城市的财政压力弱化了城市加权中心度对其科技创新绩效的促进作用。此外,本文对长三角城际科技合作网络的整体结构及演进进行了分析,发现上海、合肥、南京、杭州等城市发挥了中心合作者的作用,各城市圈内部有着更为密切的合作。基于实证分析结果,本研究认为在实践层面应进一步提高城际科技合作的广度与深度,并在财政预算上对科技创新予以更多保障和支持。

Abstract:

In order to open the "black box" of how collaborative networks affect individual performance, this paper proposes the mechanism of "collaborative network - budget input - individual performance" by using the theories of collaborative network and Resource-based View, and collects the data of urban scientific and technology(ST) collaborative networks of 41 cities in the Yangtze River Delta from 2011 to 2020. Social network analysis and panel data regression analysis are employed to test the hypotheses. The empirical results show that: (1) In the self-organized intercity ST collaborative network, the higher the city"s weighted centrality, the higher the city"s ST innovation performance; (2) ST budget expenditure has an important intermediary effect, which means the weighted centrality of a city improves the ST budget expenditure of a city, thereby improving its ST innovation performance; (3) city’s fiscal pressure of the city weakens the promotion effect of the weighted centrality on city’s ST innovation performance. In addition, this paper analyzes the overall structure and evolution of the Yangtze River Delta intercity ST collaborative network, and finds that cities like Shanghai, Hefei, Nanjing, Hangzhou play the role of central collaborators. Based on the results of empirical results, this study believes that the scope and depth of intercity collaboration in ST should be further strengthen, and more fiscal support should be given to it.
