The evaluation index system for the selection of railway container hub nodes is screened and constructed from the three aspects of regional economic development level, node capacity scale and transportation network structure conditions. On the basis of 18 railway container hubs, 4 cities, Jinan, Lianyungang, Nanning and Hefei, are added, and finally 22 cities are taken as the alternative cities, and entropy value method and entropy weight TOPSIS method are utilized to comprehensively evaluate the alternative city nodes respectively. Using the comprehensive evaluation results to transform the traditional gravity model, the improved gravity model applicable to hub selection is obtained. After comprehensively analyzing the evaluation results of the indicators and the total gravitational value of the cities calculated by the improved gravitational model, and combining with the geographical factors, Jinan, Wuhan, Chongqing, Shanghai, Guangzhou, Tianjin and Hefei are finally selected as the hub cities of the railway container transport network.
