Spatial Pattern of Regional Comprehensive Transportation Cost——The Case of Jiangsu Province

In macroscopic,regional comprehensive transportation cost is relative to regional integrated transportation accessibility and the scale of passenger and freight.With the formation of some relative conception,choosing the counties as the basic research units and GIS as the support technology,from the macroscopic view,the comprehensive transportation cost in Jiangsu Province is calculated and its pattern is analyzed in this paper.The result shows that the southern Jiangsu Province is superior to the northern one in all three indices—the integrated transportation accessibility,passenger and freight scale,and the comprehensive transportation cost.But there are some differences among three indices about the spatial structure.It takes on dual-nuclei pattern in integrated transportation accessibility,and islands-shaped pattern in passenger and freight scale,and both the two patterns are showed in the comprehensive transportation cost,i.e.,dual-nuclei pattern in south and islands-shaped pattern in north.In the economic statistics,Jiangsu Province involves three areas,the southern,the central and the northern of Jiangsu.The southern Jiangsu is the best one in all the three indices,and the central Jiangsu is better than the northern Jiangsu.As to the equilibrium among three areas,the northern Jiangsu is better than the central Jiangsu,and the southern Jiangsu is the worst areas in the integrated transportation accessibility and comprehensive transport cost.In the passenger and freight scale,the central Jiangsu is the most balanced one;the northern Jiangsu takes the second place.With those results,some measures are proposed to decrease the comprehensive transportation cost in central and northern Jiangsu Province,and its imbalance within southern Jiangsu Province.Also,some relative focus needing more attention is put forward.
