绿色发展是区域高质量发展的核心内容之一，其时空格局演变与驱动机制分析有助于为政策制定提供科学依据。从绿色经济、绿色生产、绿色环境、绿色生态、绿色创新和绿色生活6个维度遴选构建长江经济带绿色发展水平评价指标体系，运用面板熵值-Critic法、Kernel核密度估计、空间自相关分析、空间杜宾模型等方法，探究2010~2019年长江经济带108个地级及以上城市绿色发展水平时空分异特征与影响因子，结果表明：（1）2010~2019年，长江经济带绿色发展水平总体呈上升趋势，空间分异特征较为显著，且整体差异逐渐扩大；（2）长江经济带绿色发展水平整体上存在空间依存和空间外溢性，且具有相对明显的空间俱乐部收敛特征，H-H集聚区主要位于下游地区的江浙沪一带，L-L集聚区分散分布于云贵川地区，带内两极分化现象较为明显；（3）经济发展、环境规制、科技进步、产业结构优化、政府支持力度、人力资源与自然资源条件对区域内以及区域间绿色发展均具有重要的正面影响。

Green development is one of the core elements of regional high-quality development. An analysis of the spatial-temporal pattern evolution and its driving mechanism can help provide a scientific basis for policy formulation. This paper constructs the evaluation index system of green development level of Yangtze River Economic Belt from six dimensions: green economy, green production, green environment, green ecology, green innovation and green living. The panel entropy-Critic method, kernel density estimation, spatial autocorrelation analysis and spatial Durbin model are used to explore the green development level of 108 prefecture-level cities in Yangtze River Economic Belt from 2010 to 2019. The results show that (1) the overall green development level of the Yangtze River Economic Belt shows an increasing trend, with relatively significant spatial divergence characteristics and gradually expanding overall differences; (2) the overall green development level of the Yangtze River Economic Belt has spatial dependence and spatial spillover, and has relatively obvious spatial club convergence characteristics, with the H-H agglomeration area. The H-H agglomeration is mainly located in the downstream region of Jiangsu, Zhejiang and Shanghai, while the L-L agglomeration is scattered in Yunnan, Guizhou and Sichuan, and the polarization phenomenon within the belt is quite obvious; (3) economic development, environmental regulation, scientific and technological progress, industrial structure optimization, government support, human resources and natural resources conditions obviously have positive effects on green development within and between regions.
