Urban Innovation Resilience and Improvement in China:From the Perspective of Transportation Infrastructure Construction
Based on the panel data of prefecture-level cities in China,this paper uses the common factor model to measure the innova-tion resilience of Chinese cities,explains the impact mechanism of transportation infrastructure construction on urban innovation resili-ence,and takes the opening of urban high-speed rail as a quasi-natural experiment for empirical test.The findings are as follows:①China's urban innovation resilience presents regional imbalances.The eastern region is the highest,followed by the central region,and the western region is the lowest.②High-speed rail has significantly improved the resilience of urban innovation.The opening of high-speed rail has increased the urban innovation resilience by about 1.355 units,but there is an"optimal radius"for this effect.③The function differentiation of cities in the high-speed rail network leads to the heterogeneity processing effect of the opening of high-speed rail.The higher the connection breadth and centrality of cities in the high-speed rail network,the greater the effect of the opening of high-speed rail on the improvement of urban innovation resilience.④By attracting population inflows,new enterprises entering,and enhancing the level of industrial diversification and agglomeration,the opening of high-speed rail has improved urban innovation resili-ence.⑤While promoting the free flow of innovative elements,the opening of high-speed rail also widens the spatial gap of urban inno-vation resilience.
