低碳物流与区域经济耦合及驱动因素研究——基于重庆市数据实证检验

On the Coupling and Driving Factors of Low-carbon Logistics and Regional Economy——An Empirical Analysis Based on Chongqing Data

基于熵值法、耦合协同度模型、灰色关联度模型等方法,研究2012—2021年重庆市低碳物流与区域经济耦合协调发展以及驱动因素。结果表明:(1)重庆市低碳物流系统与区域经济系统的综合发展水平逐年提高。(2)通过线性回归分析表明两系统存在显著的耦合协调互动效应,两系统的耦合协调等级由严重失调到优质协调。(3)制约低碳物流与区域经济综合水平发展的主要是物流技术水平和区域经济总量两个模块的各项指标。(4)在分析两个系统的耦合协调度和低碳物流发展情况的灰色关联度时,科研经费支出被认为是最重要的驱动因素。

Based on entropy method,coupling cooperation degree model,grey correlation degree model and other methods,this paper studies the coupling and coordinated development as well as the driving factors of low-carbon logistics and regional economy in Chongqing from 2012 to 2021.The results show that:(1)the comprehensive development of low-carbon logistics system and regional economic system in Chongqing is improving year by year;(2)the linear regression analysis shows that there is a significant coupling coordination interaction effect between the two systems,and the coupling coordination degree of the two systems has transitioned from severe imbalance to high-quality coordination;(3)the main constraints on the development of low-carbon logistics and the comprehensive development of regional economy are the indicators of the two modules of logistics technology and regional economy;(4)in the analysis of the coupling coordination degree of the two systems and the grey correlation degree of low-carbon logistics development,the expenditure of scientific research funds is considered to be the most important driving factor.
