Impact of China Railway High-speed connectivity on corporate cross-regional cooper-ative innovation and its mechanisms
摘要
Abstract
Cross-regional cooperation among innovation subjects is an effective method to respond to and solve the dilemma of existing innovation needs and is an important way of creating a scientific and technological innovation community by utilizing the innovation syn-ergy of research subjects.From the perspective of corporate cross-regional cooperative innovation,this study theoretically analyzed the mechanisms of China Railway High-speed(CRH)connectivity in promoting such innovation.Using the panel data of patent applications from CRH connectivity and'enterprise-city relationship pairs'from 2005 to 2019,we empirically tested the impact and mechanisms of CRH connectivity on the optimization of innovation space for enterprises by adopting the multi-period differences-in-differences method.The results showed that:① CRH connectivity between cities where enterprises were located and cities where partners were located sig-nificantly increased the number of cooperative patent applications.This conclusion remained robust after the endogenetic test,parallel trend test,placebo test,and robustness test.② Under the influence of CRH connectivity,the number of objects of corporate cooperative innovation increased significantly,but they mainly sought such innovation within close distances and close central cities,showing the spatial contraction effect and spatial classification effect of'agglomeration in dispersion.'③ CRH connectivity also enhanced the quali-ty of cooperative innovation,transforming low-quality cooperative innovation within short distances into high-quality cooperative innova-tion,indicating a spatial stratification effect.Further research showed that:① CRH connectivity mainly promoted cooperative innovation of non-manufacturing enterprises,without a significant promoting effect on manufacturing enterprises.② CRH connectivity increased the number of patent application by enterprises with state-owned capital in cross-regional cooperation,but had no obvious impact on pri-vate,foreign,and other enterprises.③ CRH connectivity could improve the cooperative innovation level of large enterprises,but the ef-fect on relatively small enterprises was not significant.The research conclusions can provide new insights for governments to promote the establishment of innovation consortiums led by enterprises and improve the construction of innovation system.It is suggested that the CRH network layout should be continuously optimized and improved to connect more potential cities to the network.关键词
