国际枢纽城市交通区位优势与双循环优势耦合研究

Coupling Relationship between Traffic Location Dominance and Dual Circulation Superiority of International Transportation Hub Cities

在构建国内国际双循环的新发展格局下,交通作为连接生产和消费的基础环节,是扩大循环规模、提高循环效率的重要依托。以我国20个国际交通枢纽城市为研究对象,构建交通区位优势度的评价模型和城市双循环优势的评价指标体系,并进一步对交通区位优势度与双循环优势度的耦合协调度展开研究,分析两者空间分布格局。研究结果表明,我国国际交通枢纽城市的交通区位优势与双循环优势的耦合协调程度基本处于中低水平,仍有很大提升空间;从空间上看,我国国际枢纽城市的交通区位优势和双循环优势的耦合度和耦合协调度都存在着明显差异,并呈现出明显的圈层结构;交通区位优势与双循环优势的耦合协调度地区分布与双循环优势存在较强的空间对应关系。

Under the new development pattern of dual circulation in China and abroad,transportation is an important support to expand the scale and improve the efficiency of the circulation.This paper took 20 international transport hub cities as objects for analysis and constructed the evaluation model of traffic location dominance and the evaluation index system of urban dual circulation superiority.Then,by studying the coupling and coordination degree between traffic location dominance and dual circulation superiority,this paper analyzed their spatial distribution characteristics.The results show that the coupling and coordination degree between traffic location dominance and dual circulation superiority of international transportation hub cities in China is basically at a low level,and there is still much potential for improvement;there are obvious differences in the coupling and coordination degree between traffic location dominance and dual circulation superiority in these international hub cities,showing obvious layer structure;the regional distribution of coupling and coordination degree between traffic location dominance and dual circulation superiority has a strong spatial correspondence with the dual circulation superiority.
