How High-speed Rail Network Promotes Inter-city Collaborative Innovation?Empirical Analysis Based on High-speed Rail Network Accessibility and Co-patents
This paper uses the panel data of city pairs composed of 282 prefecture-level and above cities in China from 2008 to 2019 to establish databases on rail travel time and inter-city co-patents,respectively,to examine the effects of HSR network accessibility on promoting inter-city collaborative innovation based on spatial interaction theory.The study indicates that HSR network accessibility enhances inter-city collaborative innovation output.From the perspective of city linkages,HSR network accessibility contributes to inter-city collaborative innovation output by promoting technological and market linkages between cities.However,variations exist in the promoting impact of HSR network accessibility on inter-city collaborative innovation,based on geographical distance between cities and direct access to HSR network.The findings of this paper provide policy reference for improving the regional innovation pattern and the division of labor among cities along HSR lines.
