The Impact Of High-speed Railway On The Evolution Of Urban Agglomeration Industry Pattern

Few papers show the impact of high-speed railway on the evolution of urban agglomeration industry Pattern from the perspective of theory and empirical analysis.So,from this perspective,this article try to do a preliminary discussion.Firstly,this paper starts from the theoretical point of view,systematically analysis the impact of high-speed railway on the evolution of urban agglomeration industry Pattern,and then reveals and validates the impact of high speed railway on the industrial pattern of 16 cities in Yangtze River Delta.The influence mechanism of the impact of high-speed railway on the evolution of urban agglomeration industry pattern is the comprehensive influence of the high-speed railway from the planning,construction,construction and operation of the industrial structure of the urban agglomeration along the high-speed railway.High-speed railway by changing the accessibility of the city of the urban agglomeration to enhance the factor flow speed,thus affecting the agglomeration and transfer between the city agglomeration,and the mutual influence of industrial layout and space layout of the city to promote the evolution of industrial structure of the whole city group,and ultimately affect the pattern of development of the whole urban agglomeration.From the industrial structure similarity coefficient shows that 16 cities in Yangtze River Delta in the high speed railway(2006-2010)and after the opening(2010-2014),one or two,three industrial structure similarity coefficient is very high,similar to standard coefficient from the industrial structure(in 0.90 circles),does exist between the three the problem of the convergence of industrial structure.According to the analysis results of global autocorrelation,there is a significant phenomenon of industrial spatial agglomeration in the 16 cities of Yangtze River delta.From the static and dynamic clustering index results,the 16 cities in the Yangtze River Delta outward transfer industry more than 10 of the city has increased,and the transfer of professional is not only the traditional labor-intensive industries and resource intensive industries,a high and new technology industry have outward transfer trend that,during 2006-2014,16 cities in Yangtze River Delta has obvious trend of industrial transfer.Finally,we introduce the DID model to the textile industry,ferrous metal smelting and rolling processing industry,pharmaceutical industry,real estate industry four industry empirical regression analysis,results show that the siphon effect and diffusion effect of high iron production,accelerate the textile industry and ferrous metal smelting and rolling processing industry and other traditional industries to transfer it makes the medicine manufacturing industry,high-tech industry cluster in the core city,and in the analysis of the real estate industry,regression results are not very significant,but can be found in Suzhou,Jiaxing and other similar near the city of Shanghai,in the high speed railway,high speed railway investment in real estate development by their growth rate has been improved greatly,the high speed rail,driven around the city of Shanghai City real estate development.The regression results of the above four typical industries also indicate that the high speed railway provides a two-way channel support for the industrial agglomeration and transfer of the urban agglomeration,which ultimately affects the industrial structure of the urban agglomeration.
