Evolution of Structure Characteristics and Network Effects of Railway Passenger Transport Network in Chengdu-Chongqing Economic Circle
摘要
Abstract
The analysis of the spatial connection and structural characteristics evolution of the railway passenger transport network in Chengdu-Chongqing Economic Circle is of great significance to the future network construction and layout optimization.This paper constructs the railway passenger transport network of Chengdu-Chongqing Economic Circle based on the 46 863 617 railway passenger transport data,and uses GIS spatial analysis and social network analysis methods to analyze the space-time evolution of railway passenger transport links,the evolution of structure characteristics and the impact of network structure on economy and population in continuous time series.The results show that the polarization of railway passenger transport links in Chengdu Chongqing Economic Circle is obvious,and the passenger transport flow is mainly concentrated in Chengdu,followed by Mianyang,the main districts of Chongqing and Deyang,and other cities account for less than 20％of the passenger transport flow.The density of railway passenger transport network in Chengdu-Chongqing Economic Circle is increasing year by year,but it is still at a low level.The railway passenger transport network has a low average path length and a high average clustering coefficient,and it is characterized by a small world.The degree centrality and betweenness centrality of Chengdu and the main districts of Chongqing are far more than those of other cities.The accessibility of railway passenger transport in Chengdu-Chongqing Economic Circle is largely due to the intermediary role of Chengdu and the main districts of Chongqing.There is no railway passenger transport connection between most cities.The degree centrality,proximity centrality and intermediate centrality have positive effects on GDP,and pass the 1％significance level test.The degree centrality and intermediate centrality have negative impacts on the population,and pass the significance level tests of 5％and 10％respectively.Cities in the central position are not conducive to the permanent residence of the population.关键词
