Study On The Influence Of Guiyang-guangzhou High-speed Rail On Regional Factor Flow Along The Line

Regional factor flow is an important process that affects regional economic growth and changes of regional economic pattern.The development of transportation triggers regional factor flow by changing the location conditions of cities along the line.In recent years,with the full implementation of the National Medium and Long Term Railway Network Planning,the layout of high-speed rail network in China continues to expand,and high-speed rail has become an important means of transportation for people to travel.The development of high-speed rail will have a wide and far-reaching impact on the flow of regional factors along the line.This paper takes the station cities along Guiyang-Guangzhou high-speed rail as the research object,and carries out an in-depth study on the flow of regional factors along the line.Firstly,by summarizing the research results of domestic and foreign scholars on the impact of high-speed rail on regional factor flow,combining with the relevant theoretical basis,the research background,significance and research methods of the paper are summarized;secondly,the regional accessibility and relevance under the influence of high-speed rail are measured and analyzed;and the spatial distribution of regional factors is analyzed by social network analysis method.Based on the idea of "yes" and "no" comparison,time series analysis and factor analysis are used to empirically study the impact of high-speed rail on regional factor flow along the route.Finally,according to the impact of high-speed rail on factor flow,some countermeasures and suggestions are put forward to promote the free flow of resources among regions,rational allocation and achieve balanced regional development.Based on the study of the influence of Guiyang-Guangzhou high-speed rail on regional factor flow,the following conclusions are drawn through layer-by-layer analysis:(1)The construction of high-speed rail has significantly improved the level of accessibility and correlation between cities along the route;(2)The trend of factor flow has remained largely unchanged before and after the opening of high-speed rail,and a large number of elements are still clustered in regions with strong economic strength,but the intensity of factor flow has changed in different regions;(3)The opening of high-speed rail has played a positive role in attracting factors in different levels of cities,but the degree of promotion is different: Cities with good development foundation benefit most from high-speed rail;Cities with relatively poor development foundation are in the middle of the three types of cities in terms of their factor attraction ability due to the increase of high-speed rail;High-speed rail has not significantly improved the ability to attract factors of developed cities,but has played a role in enhancing its sustainable growth.
