The Influence of High-speed Railway on the Factor Resources Flow in the Yangtze River Delta Urban Agglomeration Based on Experimental and Mathematical Statistics Analysis

Abstract

High-speed railway is exerting a profound influence on China's economic development. However, among the more and more research results on the economic effect of highspeed railway, there is still a lack of research on the impact of high-speed rail on the factor resources flow from the perspective of urban agglomeration. So this paper conducted an empirical study based on panel data from 2008 to 2019 on 26 cities in the Yangtze River Delta Urban Agglomeration, calculated the labor flow index and the capital flow index as the dependent variables, and the interaction item of whether high-speed railway has opened or not was taken as dummy variable, and 6 control variables are introduced into the multi-period DID model. And the parallel trend test is also carried out. The empirical results represent that the opening of high-speed railway has no significant impact on labor flow, but high-speed railway can significantly promote the capital flow in the Yangtze River Delta, and this impact will gradually increase as time goes by. In addition, testing results of different samples show that high-speed railway has a more significant effect on capital flow in megacities than in large and medium-sized cities. According to the model results, some suggestions are put forward from the perspective of promoting the coordinated development of the Yangtze River Delta area.
