交通区位优势与双循环枢纽链接优势测度及转化对策研究OA北大核心

As an important node connecting the national comprehensive transportation network,hub cities play a radiating and driving role in cities and actively integrate into the new development pattern of dual circulation,which is an inevitable requirement for development.Taking 20 international hub cities as research objects,this paper conducted an evaluation system for transportation location advantages and dual circulation hub link advantages.The extreme value method was utilized to standardize the data and calculate the transportation location advantage degree of each city.The entropy weight TOPSIS method was adopted to calculate the transportation location advantages and dual circulation hub link advantages.At the same time,the causal relationship and coupling coordination scheduling of the two transformations were studied.According to calculations,Shenzhen,Beijing,and Shanghai all rank among the top three cities in terms of transportation location advantages and dual circulation hub link advantages and are in a high-level coupling and high-quality coordination degree.Cities with a low to medium level coordination degree can start from three aspects:channel construction,hub level,and hub economy to enhance the supporting role of transportation location in economic development and accelerate the transformation of its transportation location advantage into a dual circulation hub link advantage.
