How to effectively promote low-carbon transformation is the key to achieving carbon peak and car-bon neutrality goals,and moving towards green and high-quality development. In recent years,the govern-ment has continuously standardized and improved the cooperation mechanism between the government and social capital. The introduction of the public-private partnership (PPP) model into the green field is China' s market-oriented exploration to improve the quality of green public service supply. Based on city level data from 2005 to 2021,this article views green PPP practice as a policy shock and constructs difference-in-difference model to comprehensively explore the impact of green PPP practice on carbon emission . This ar-ticle found that green PPP practices have effectively reduced carbon emissions. After a series of tests such as common trend and endogeneity,the basic conclusion still holds. Heterogeneity analysis found that green PPP projects with payment forms such as government payments and feasibility gap subsidies,and operating modes such as BOT and TOT,have significant carbon emission reduction effects,and the carbon emission reduction effect is not affected by the project cooperation period. Mechanism analysis shows that green PPP practices can accelerate carbon reduction through green technology innovation and enhancing marketization. Further analysis reveals that public supervision and attention can help the government,enterprises,and so-ciety form a joint force in environmental governance,improve the supply efficiency and quality of green pub-lic services,and strengthen the low-carbon environmental effect of green PPP. This article provides reference for China to further standardize and improve PPP mechanism in the future to help achieve carbon peak and carbon neutrality strategic goals,and promote green and high-quality development.
