A Research Of Logistics Network And Correlation Of The Domestic Node Cities At China Railway Express

In 2011,Chongqing New Europe opened the first China-Europe freight Railway Express,Up till now more than 20 city has opened the China Railway Express.During the opening process,there are many problems such as insufficient supply,disorderly competition,high government subsidies and low cost.At present,most of the researches on China Railway Express are limited to a qualitative research.However,researches combining both quality and quantity on the selection of railway transit hub cities in China Railway Express are not frequently seen.By means of factor analysis,this paper calculates the comprehensive development level of the China Railway Express Union City logistics,and uses the revised integrated gravitational model to calculate the logistics connection intensity of the 18 node cities.Then the social network analysis method is used to analyze the integrated gravity of each logistics node from four aspects of network density,network centrality,cohesive subgroup and core-edge.The results show that the network density is small,the influence on each node city is not strong,and the interaction between the node cities is not strong.The central degree of the six nodes in Tianjin,Wuhan,Zhengzhou,Xi'an,Chongqing and Suzhou is the core of the node network.His node city has strong logistics radiation capability and plays an important role in the logistics relationship of the whole node city network.In the near future,we can choose Tianjin,Zhengzhou,Wuhan,Chongqing and Xi'an as China Railway Express transfer hub cities.When the China Railway Express will have developed to support more urban opening classes,Tianjin,Zhengzhou,Wuhan,Chongqing,Xi'an,Suzhou,Shenyang and Urumqi can be developed as transit hub cities.Finally,combined with the conclusions of this study,three suggestions for the development of China Railway Express are given: top-level design,overall planning,market-oriented,integration of local interests,the implementation of transfer model,and the improvement of hub nodes.
