This study explored the impact of industrial agglomeration on carbon neutrality and its spatial spillover effects utilizing the expanded the output density theoretical model of Ciccone and Hall. The main findings are as follows: (1) In terms of long-term effects, industrial output has significantly reduced regional carbon emissions, while industrial labor and capital agglomeration have aggravated carbon emissions, and industrial technology agglomeration has no significant impact on carbon emissions. (2) From the perspective of lagging effects, industrial output agglomeration has significantly increased regional carbon emissions, while industrial technology agglomeration has effectively reduced carbon emissions. The lagging effects of industrial labor and capital agglomeration are not significant. (3) From the perspective of regional differences, there are significant regional differences in the impact of industrial output and capital agglomeration on regional carbon emissions, while this differential influence does not exist on industrial labor and technological agglomeration. Therefore, in carbon emissions governance, it is necessary to analyze the long-term impact of industrial agglomeration on carbon emissions but also to pay attention to the lag and regional differences of the impact.
本研究利用西库恩和霍尔扩展的产出密度理论模型，探讨了产业集聚对碳中性的影响及其空间溢出效应。主要发现如下：（1）从长期效应来看，工业产出显著降低了区域碳排放，而工业劳动力和资本集聚加剧了碳排放，工业技术集聚对碳排放没有显著影响。（2）从时滞效应来看，工业产出集聚显著增加了区域碳排放，而工业技术集聚有效地降低了碳排放。工业劳动力和资本集聚的时滞效应不显著。（3）从区域差异来看，工业产出和资本集聚对区域碳排放的影响存在显著的区域差异，而工业劳动力和技术集聚的影响则不存在这种差异。因此，在碳排放治理中，有必要分析产业集聚对碳排放的长期影响，同时也要关注影响的时滞和区域差异。
