With rapid urbanization and industrialization, ecological disorders and environmental degradation have become serious, and the promotion of the coordinated development of the social economy and ecological environment is not only a pressing problem to be solved, but also an important step towards sustainable development. The coordinated development of the social economy and eco-environment is conducive to sustainable development. Considering the Chengdu-Chongqing urban agglomeration as a case study, this paper adopts panel data and establishes an index system to evaluate the coupling coordination degree (CCD) between the social economy and ecological environment based on the concept of high-quality development. From the perspective of time and space, the changing laws and characteristics of the CCD are analyzed, and the key factors affecting it are determined using regression analysis. The results show the following: (1) the CCD between the social economy and ecological environment of the Chengdu-Chongqing urban agglomeration presents a low level overall; (2) the CCD in more developed regions is significantly higher than that in less developed regions; thus, the characteristics of spatial differences are obvious; (3) the urbanization rate, ratio of actual use of foreign capital and GDP, ratio of total export-import volume and GDP, proportion of days with good air quality, and per capita public green space area are the main factors affecting the coordinated development of the social economy and ecological environment in the Chengdu-Chongqing urban agglomeration; and (4) Chongqing has obvious endogeneity. Finally, corresponding policy recommendations are provided aimed at promoting rapid economic development in the Chengdu-Chongqing urban agglomeration while focusing on environmental protection and promoting high-quality economic development with ecological environmental protection, while putting forward decision-making suggestions for high-quality development of urban agglomerations.
随着城市化和工业化的快速发展，生态失调和环境恶化已成为严重问题，促进社会经济与生态环境协调发展不仅是亟待解决的问题，也是实现可持续发展的重要步骤。社会经济与生态环境的协调发展有利于可持续发展。本文以成渝城市群为例，采用面板数据，基于高质量发展理念构建了评价社会经济与生态环境耦合协调度（CCD）的指标体系，从时间和空间两个角度分析了 CCD 的变化规律和特征，并利用回归分析确定了影响其发展的关键因素。结果表明：（1）成渝城市群社会经济与生态环境的 CCD 整体水平较低；（2）发达地区的 CCD 明显高于欠发达地区，因此具有明显的空间差异特征；（3）城市化率、实际利用外资与 GDP 之比、进出口总额与 GDP 之比、空气质量优良天数比例和人均公共绿地面积是影响成渝城市群社会经济与生态环境协调发展的主要因素；（4）重庆存在明显的内生性。最后，针对成渝城市群的快速经济发展与环境保护，提出了促进经济高质量发展与生态环境保护的政策建议，为城市群的高质量发展提供了决策参考。
