摘　　要：随着我国经济的飞速发展和城市化进程的加速,城市群逐渐成为碳排放的主要来源,如何有效地控制并减少城市群碳排放成为一个紧迫的议题.本研究基于城市面板数据,利用空间自相关和空间计量回归模型分析了我国长三角、京津冀、珠三角及成渝城市群碳排放时空格局特征,并且从经济社会和环境治理行为方面探讨了城市群碳排放影响机制.结果表明,城市群碳排放时空格局深受其内部功能特征的影响,并表现出特定的演变趋势.此外,合理的环境管理和城市间协作可以有效促进城市群可持续发展.基于以上发现,研究提出应充分考虑到各城市群的功能特征以及碳排放的时空格局,并针对具体的碳排放影响机制来制定差异化减碳策略.With the rapid development of our country's economy and the accelerated process of urbanization,urban agglomerations have gradually emerged as the primary contributors to carbon emissions.Effectively controlling and reducing carbon emissions from urban agglomerations has become an urgent issue.This study,based on urban panel data,employs spatial autocorrelation and spatial econometric regression models to analyze the spatiotemporal patterns of carbon emissions in China's Yangtze River Delta,Beijing-Tianjin-Hebei region,Pearl River Delta,and Chengdu-Chongqing urban agglomerations.Furthermore,the research explores the influencing mechanisms of carbon emissions from urban agglomerations in terms of economic,social,and environmental governance behaviors.The findings of the study indicate that the spatiotemporal patterns of carbon emissions in urban agglomerations are profoundly influenced by their internal functional characteristics,exhibiting specific evolving trends.Additionally,rational environmental management and inter-city cooperation can effectively promote the sustainable development of urban agglomerations.Based on these discoveries,the research proposes that due consideration should be given to the functional characteristics of each urban agglomeration and the spatiotemporal patterns of carbon emissions.Tailored decarbonization strategies should be formulated based on specific carbon emission influencing mechanisms.
