An Empirical Study On The Impact Of High-speed Railway On China’s Industrial Structure

Industrial upgrading is a very rich concept,which is an important indicator of the regional economic development.With the rapid development of China’s high-speed railway,various regions have optimized the allocation of resources,improved the industrial layout of site cities,and further deepened the industrial structure of cities along the route.This new development model of the high-speed rail economy has become a new trend.However,due to the different opening conditions of high-speed railways,the characteristics and economic development conditions of the city are different,and the level of urban industrial structure will be significantly affected by the opening of highspeed railways.Investigate the impact of high-speed rail openings on the urban industrial structure,and rationally evaluate the city the industrial effect of high-speed railway is of great significance in formulating industrial development policies.Especially in the environment of increasing economic downward pressure,it has important reference significance for local governments to make full use of the economic effects of high-speed railway for industrial optimization and adjustment.This article reveals the impact of high-speed rail on the heightening of industrial structure from both theoretical and empirical perspectives.In the theoretical analysis part,systematically analyze the mechanism of the impact of high-speed rail on the urban industrial structure from two perspectives: the general impact path of the industrial structure heightening and the impact path of the high-speed rail on the industrial structure heightening.The evaluation system,and score calculation through factor analysis,as a proxy variable for the industrialization of the industry.Taking 267 prefecture-level cities in China as the research object,in the early stage of preparation,the website of 12306 was used to crawl the express train and high-speed rail transit time between 267 city pairs,and according to the information of more than 2500 high-speed trains,the city pairs were organized The panel data of transit time is used as the proxy variable of high-speed rail.In the data analysis stage,the proximity matrix and the distance matrix are constructed at the national level,the spatial correlation test is carried out,and the local agglomeration is analyzed,the spatial econometric model is established,the degree of impact of the highspeed rail on the urban industrial structure is analyzed,and the high-speed rail is verified at different levels The mechanism of impact on the industrialization of the industry.This paper believes that:(1)the level of industrial structure between cities has obvious spatial correlation,there is agglomeration effect,and the urban industrial structure will be affected by the surrounding cities.The test results of the adjacent spatial weight matrix and the distance spatial weight matrix both passed the significance test,and the spatial overflow coefficient was between 0.2529 and 0.2699.(2)The high-speed rail has a significant role in promoting the upgrading of the industrial structure by improving the accessibility of the city,accelerating the flow of factors and improving the urban market structure.The contribution rate of the high-speed rail to the heightening of the industrial structure is 2.8326 ～ 5.7862.(3)By decomposing the advanced industrial structure and using the accessibility variables for regression,it is obtained that high-speed rail has an impact on the four dimensions of the advanced industrial structure,further confirming the robustness of the regression results.
