Evaluation Of Logistics Competitiveness Of Core Cities In The Yangtze River Economic Belt

In recent years,logistics has developed rapidly in the world and entered the daily life of cities.The need of urban scale expansion and regional integration development for the transfer of means of production has highlighted the importance of logistics.The Yangtze River Economic Belt runs through the east and west of China,gathering rich natural resources and high-tech industries.Its GDP accounts for nearly half of the country’s GDP.The country has formulated major development strategies to promote the development of the region many times.However,the geographical location span of each province and city in the region is large,the focus of economic development is different,and the logistics level is not balanced.Therefore,studying the level difference of logistics competitiveness of core cities in the Yangtze River Economic Belt will play a positive role in promoting the reconstruction of urban logistics spatial network among regions and promoting the high-quality development of regional integration.On the basis of reference to the existing evaluation system of urban logistics competitiveness,this paper adds relevant indicators of urban logistics green level and urban logistics security level,and constructs an evaluation system of logistics competitiveness of core cities in the Yangtze River Economic Belt,which includes 22 indicators.Firstly,entropy method and CRITIC method are selected to calculate the weight calculation,fully considering the relevance and dispersion of indicators;Secondly,the method of Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS)is used to calculate the distance between the positive and negative ideal solutions and the closeness degree of the scheme,and finally the Adversarial Interpretive Structure Modeling Method(AISM)is used to calculate by gradually approximate the above results.Finally,the logistics competitiveness ranking of 11 core cities in the Yangtze River Economic Belt is obtained.The results are as follows:Shanghai>Chongqing>Hangzhou>Chengdu>Wuhan>Nanjing>Changsha>Hefei>Guiya ng>Kunming>Nanchang.Based on the original data of indicators,we can find the advantages and disadvantages of the development of logistics capacity of each city in the economic belt,and put forward corresponding development suggestions.In the research on the logistics competitiveness of core cities in the Yangtze River Economic Belt,the structural model of confrontation interpretation based on TOPSIS is used to conduct game analysis from the two opposite angles of cause priority and result priority,avoiding possible result errors in single angle calculation;The evaluation results are displayed through directed topology graph,which is convenient for readers to quickly obtain conclusion information.This visual presentation of the conclusions from multiple perspectives can more clearly identify the level of the sample cities,and provide some reference for the analysis and research of urban logistics competitiveness in the future.Figure [ 9 ] Table [ 15 ] Reference [ 80 ]...
