Abstract In order to reduce carbon emissions and improve environmental governance, the paper discusses the interactive forms of environmental regulation based on the two-regime spatial Durbin model. The effects of environmental regulation and interactive behavior of environmental regulation on carbon dioxide (CO2) emissions are explored by using the spatial lag of X (SLX) model. It is found that there is a diversified competitive behavior in the enforcement of environmental regulation among local governments in China. And the diversified competitive behavior results in the nearby transfer of pollution, which increases local CO2 emissions. In addition, there is an inverted "U" curve between environmental regulation and CO2 emissions, and China is still in the "green paradox" stage. Furthermore, it is found that the environmental regulation mainly affects CO2 emissions through industrial structure and technological progress. Also, there are differences in the spatial spillover effect of environmental regulation due to the existence of regional heterogeneity, and its impact on CO2 is particularly significant in the western region. The findings indicate that the central government should strengthen targeted supervision and adaptive incentives for local governments to implement environmental regulation so that joint emission reduction can be promoted.

环境监管与CO2排放：基于环境治理的战略互动

摘要 为减少碳排放，完善环境治理，本文基于二元空间杜宾模型探讨了环境规制的互动形式。利用X空间滞后（SLX）模型探讨了环境规制和环境规制交互行为对二氧化碳（CO2）排放的影响。研究发现，我国地方政府在环境规制执法中存在着多元化的竞争行为。而多样化的竞争行为导致污染就近转移，增加了当地的二氧化碳排放量。此外，环境规制与CO2排放之间存在倒“U”型曲线，我国仍处于“绿色悖论”阶段。此外，发现环境规制主要通过产业结构和技术进步影响CO2排放。同时，由于区域异质性的存在，环境规制的空间溢出效应存在差异，对CO2的影响在西部地区尤为显着。研究结果表明，中央政府应加强对地方政府实施环境监管的针对性监管和适应性激励，以促进联合减排。而其对 CO2 的影响在西部地区尤为显着。研究结果表明，中央政府应加强对地方政府实施环境监管的针对性监管和适应性激励，以促进联合减排。而其对 CO2 的影响在西部地区尤为显着。研究结果表明，中央政府应加强对地方政府实施环境监管的针对性监管和适应性激励，以促进联合减排。
