High-speed railways and regional knowledge innovation:Based on the literature review
The improvement of transportation infrastructure can reshape the economic geogra-phy patterns.The opening of high-speed railways promotes the flow of innovation elements among regions,enhances the knowledge spillover effect,affects regional innovation activities,or even affects the structure of regional knowledge innovation network.Based on the extant litera-ture,this article summarized the relationship between high-speed railways and knowledge inno-vation in cities along railway lines in terms of the exact impact,differential performance and the mechanism,and further explained the micro mechanism of the impact of the opening of high-speed railways on regional knowledge innovation from the perspective of enterprises.According to the literature analysis,this article draws the following conclusions.Firstly,high-speed rail-ways do have an impact on knowledge innovation,but there are regional differences,which are related to geographical distance and urban heterogeneity.Secondly,the opening of high-speed railways promotes the flow and agglomeration of innovation factors,and expands knowledge spillover effects,which will affect regional knowledge innovation.However,both the agglomer-ation effect and knowledge spillover effect have two sides,so they show different influence ef-fects in different regions.Thirdly,the opening of high-speed railways is conducive to expanding the commuting field,broadening knowledge channels and increasing temporary agglomeration,so as to increase the opportunities for enterprises to obtain innovative talents,cross-regional co-operation and knowledge sharing,and promote their innovative output.Finally,this article puts forward an analytical framework and some topics worthy of in-depth discussion.
