基于耦合模型的核心城市群综合运输与区域经济

Comprehensive transportation and regional economy of core urban agglomeration based on coupling model

成渝—粤港澳两极是国家综合立体交通网建设的重要组成部分。以成渝—粤港澳轴线核心城市群中8个城市为研究单元,利用2015—2019年5个时间节点的综合运输和区域经济发展指标数据,结合熵值法综合测算各指标权重,通过引入基于灰色关联分析方法的耦合协调度模型,更加客观、准确地探究影响综合运输与区域经济在协调效应中的关键指标和各城市间协调水平。结果表明:城市的综合运输与区域经济耦合协调水平显著提高,耦合协调水平由低水平向高水平发展;各城市间耦合协调水平存在一定差异,总体看,协调水平较高的城市集中在珠三角地区和成渝地区,耦合协调水平较弱的城市主要在华南地区东北部和中部地区,存在不平衡、不协调现象。

Chengdu/Chongqing-Guangdong/Hong Kong/Macao poles are an important part of the national comprehensive three-dimensional transportation network construction.Taking 8 cities in the core city agglomeration of the Chengdu-Chongqing-Guangdong-Hong Kong-Macao axis as the research unit,this paper uses the comprehensive transportation and regional economic development index data of 5 time nodes from 2015 to 2019,combined with the entropy method to comprehensively calculate the weight of each index,by introducing the coupling coordination degree model of the grey relational analysis method to objectively and accurately explores the key indicators that affect the coordination effect of comprehensive transportation and regional economy and the coordination level between cities.The results shows that:the level of coupling coordination between comprehensive transportation and regional economy in cities has been significantly improved,and the level of coupling coordination has developed from a low level to a high level;there are certain differences in the level of coupling coordination among cities.Cities with high levels are concentrated in the Pearl River Delta region and Chengdu-Chongqing region,while cities with weaker coupling coordination are mainly in the northeastern and central regions of South China,which are unbalanced and uncoordinated.
