【摘要】 在高质量发展背景下，协同推进数字经济和绿色经济发展十分重要。我国数字产业呈现显著的地区集聚特征，其对城市绿色转型特别是碳排放的影响机理亟待厘清。通过构建理论模型，系统解析数字产业集聚影响碳排放的核心传导路径，发现在当前发展阶段我国数字产业集聚对于碳减排有积极作用。基于城市层面的实证检验发现，数字产业集聚通过提升电力能源利用效率、促进绿色技术创新、优化资本配置效率显著抑制了城市碳排放。进一步分析表明，碳减排效应对周边城市存在显著的正向空间溢出效应，在数字产业集聚显性优势地区、高创新水平地区、人口净流入城市和非老工业城市表现得更为强劲。更多还原

【Abstract】 Under the context of high-quality development, it is crucial to collaboratively advance the digital economy and the green economy. China’s digital industry exhibits pronounced regional agglomeration characteristics, and the mechanisms by which it influences urban green transformation—particularly carbon emissions—remain to be clarified. By constructing a theoretical model, this study systematically analyzes the core transmission pathways through which digital industry agglomeration impacts carbon emissions, revealing that at the current stage of development in China, digital industry agglomeration plays a positive role in carbon emission reduction. Empirical tests at the urban level demonstrate that digital industry agglomeration significantly curbs urban carbon emissions by improving electricity and energy utilization efficiency, promoting green technological innovation, and optimizing capital allocation efficiency. Further analysis indicates that carbon emission reduction effect not only generates a significant positive spatial spillover effect on neighboring cities but also manifests more strongly in regions with distinct advantages in digital industry agglomeration, areas with high innovation levels, cities experiencing net population inflows, and non-traditional industrial cities.更多还原
