  • 摘要:人口、经济和环境协调发展是成渝地区双城经济圈协调发展及高质量发展的重要途径和关键点.本研究基于成渝地区双城经济圈36个市(区、县)面板数据,构建了人口-经济-环境系统协调发展指标体系,利用综合指标评价法、耦合模型、耦合协调模型等测算了2010—2019年成渝地区双城经济圈人口-经济-环境复合系统综合发展水平、耦合度及耦合协调度,据此分析研究时段内三元系统耦合协调的时空演变特征及规律,并对子系统发展差异性进行初探.结果表明:整体上,成渝地区双城经济圈耦合协调度和经济、环境子系统发展水平呈不断升高趋势;时序上各市(区、县)人口-经济-环境耦合协调发展关系呈良性向上发展趋势;空间上呈现“两核突出、中部塌陷,外围高于内部”的分布格局和“外围包围中部、由西向东推进”演变特征;研究时段内成渝地区双城经济圈各市(区、县)子系统滞后问题得到极大改善,呈“无序-有序、同步滞后-局部滞后”发展演变趋势和“U”型发展空间格局,但发展过程中人口子系统依旧存在较严重滞后问题.
  • Abstract:The coordinated development of population, economy and environment can be called an important approach and key point for coordinated development and high-quality development of Chengdu-Chongqing dual city economic circle. In this study, population, economy and environmental data from 2010 to 2019 is used to construct index system for coordinated development of population-economy-environment system, and then to calculate the comprehensive development index and coupling coordination degree by means of comprehensive index evaluation method and the coupling coordination degree model to. Then, based on the calculation results, the spatiotemporal variation characteristics of the coupling coordination of the population-economic-environmental system are discussed, and the differences between the development of the subsystems are preliminarily explored. The results show that: ① the coupling coordination degree of the Chengdu-Chongqing economic circle shows a rising trend, and the comprehensive development level of the economic and environmental subsystems display an upward trend; ② the coordinated development relationship of population-economy-environment coupling in each city (district and county) shows a upward development trend in time series; ③ the distribution pattern of "two cores protruding and the middle collapsing, the periphery is higher than the interior" and the evolution characteristics of "periphery encircling the middle and advancing from west to east";④ the lagging problem of the subsystems of the cities (districts and counties) in the Chengdu-Chongqing Economic Circle has been greatly improved during the research period, showing the development and evolution trend of "disorder-order, synchronous lag-local lag" and the spatial pattern of "U" development, but the population subsystem still lags behind seriously in the process of development.
