摘要
基于2010-2021年长三角41个城市的面板数据,将长三角G60科创走廊建设视为一项准自然实验,综合运用社会网络分析法、双重差分法和空间杜宾模型等方法,从理论和实证两方面检验长三角G60科创走廊对沿线城市创新合作的影响与作用机制.研究发现:①长三角G60科创走廊建设显著提高了沿线城市的跨区域创新合作水平,研究结论在一系列稳健性检验中均成立.②随着政策实施的不断推进,这一促进效应逐渐增强,但空间溢出效应仍不明显.③相较于一般等级城市,长三角G60科创走廊建设对沿线高等级城市的影响效应更大.④长三角G60科创走廊建设主要通过强化政府创新投入、缓解传统融资约束、提高数字金融发展水平、促进人才集聚,进而对沿线城市跨区域创新合作产生积极影响.
Abstract
Based on panel data of 41 cities in the Yangtze River Delta from 2010 to 2021,this paper takes the construction of G60 science and innovation corridor as a quasi-natural experiment and comprehensively uses social network analysis,DID method,and spatial Durbin model to test the impact and mechanism of G60 S&T Innovation Corridor on innovation co-operation in cities along the route.Results show that:① The construction of the G60 S&T Innovation Corridor significantly improves the level of cross-regional innovation cooperation in cities along the route,and this conclusion is still valid after a series of robustness tests.② With the continuous promotion of policy implementation,this promoting effect gradually strengthens,but the spatial spillover effect is still not obvious.③Compared to general-level cities,the G60 S&T Innova-tion Corridor has a greater impact on high-level cities along the route.④The G60 S&T Innovation Corridor has a positive impact on cross-regional innovation cooperation in cities along the route mainly by strengthening government innovation in-vestment,alleviating traditional financing constraints,improving the development level of digital finance,and promoting tal-ent agglomeration.
