Impacts of high-speed rail on the industrial developments of non-central cities in China

The high-speed rail (HSR) is one of the most important, if not the most important, emerging transportation that could exert significant influences in many areas, including economic development, social development, financial development, environmental protection, etc. This paper focuses on examining the impacts of HSR on the development of the industrial structure. Since most of the studies in this area are related to central cities (provincial capitals and municipalities directly under the central government), to fill in the gap in the literature, in this paper, we investigate the impacts of HSR on non-central cities in China. To do so, we use the propensity score matching difference-in-difference (PSM-DID) method to investigate the siphoning, spillover, and moderating effects of the opening of the HSR on the development of the industrial structure in the cities along with or nearby the HSR. In addition, we conclude both the robustness tests and the heterogeneity analysis in our study. We find that the opening of HSR significantly promotes the rationalization of non-central cities’ industrial structure, as well as improves the advancement of the industrial structure for non-central cities which are less than 100 km away from the central city. Moreover, the four moderating variables, the urban innovation index, the new urbanization construction level, the nearest distance from the central city, and the medical services insurance coverage rate, make the HSR has a positive impact on the rationalization level of industrial structure. Our findings are useful for both central and local governments and policymakers in accurately formulating policies related to the planning and construction of HSR, city planning, and planning the development of the industrial structure for each city nearby the HSR.
