高铁开通对沿线城市知识创新的影响: —基于国内外文献的分析.

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 literature, this article summarized the relationship between high-speed railways and knowledge innovation 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 agglomeration effect and knowledge spillover effect have two sides, so they show different influence effects 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. [ABSTRACT FROM AUTHOR]
