The coordination of urbanization with the ecological environment has become a significant sustainable urban development problem given the current acceleration in China's urbanization. The existing research lacks in-depth discussion on the coordination relationship between urbanization and energy eco-environment from the perspective of urban agglomeration. This paper takes the Yangtze River Delta Urban Agglomeration as its research area. The combination of CRITIC and entropy weight methods is used to measure the comprehensive urbanization level (CUL) from the four dimensions of population, economy, land, and society, and the SBM-Undesirable model is used to measure the energy eco-efficiency (EE). The spatiotemporal pattern and dynamic evolution law of the coupling coordination degree (CCD) between CUL and EE are analyzed using the coupling coordination model and the spatial Markov chain. The research results reveal that (1) from the comprehensive development level standpoint, both CUL and EE are on the rise from 2010 to 2021; however, a problem of unbalanced development is observed. (2) The overall CCD displays an upward trend and evinces significant spatial differentiation characteristics from the coordinated development level viewpoint. (3) The CCD transition state is not isolated to certain geographic spaces: adjacent cities will impact changes in the coupling coordination types of an urban center. Therefore, we propose strategies to improve the CCD between CUL and EE to offer theoretical and policy inferences for the formulation of sustainable urban development strategies.
由于中国城市化进程的加速，城市化与生态环境的协调已成为一个重大的可持续城市发展问题。现有研究缺乏从城市群角度深入探讨城市化与能源生态环境的协调关系。本文以长江三角洲城市群为研究区域，采用 CRITIC 与熵权组合赋权法从人口、经济、土地和社会四个维度测度综合城市化水平（CUL），采用 SBM-undesirable 模型测度能源生态效率（EE），运用耦合协调模型和空间马尔可夫链分析 CUL 与 EE 耦合协调度（CCD）的时空格局及动态演进规律。研究结果表明：（1）从综合发展水平看，2010—2021 年 CUL 和 EE 均呈上升趋势，但存在发展不平衡问题；（2）从协调发展水平看，整体 CCD 呈上升趋势，具有显著的空间分异特征；（3）CCD 跃迁状态并非孤立于某些地理空间：相邻城市会对中心城市的耦合协调类型变化产生影响。因此，提出提高 CUL 与 EE 之间 CCD 的策略，为制定可持续城市发展战略提供理论和政策启示。
