摘要：Based on panel data from 204 prefecture-level cities in China spanning from 2010 to 2019, this study examines the low-carbon city pilot program as a quasi-natural experiment. The propensity score matching-double difference model (PSM-DID) is utilized to analyze the effects of the low-carbon city pilot policy on carbon emission intensity. The research findings found: Firstly, the low-carbon city pilot policy has significantly reduced the intensity of urban carbon emissions. Secondly, the primary factors contributing to the reduction in urban carbon emissions intensity due to the low-carbon city pilot policy include adjustments in industrial structure, energy consumption control, and advancements in green technology innovation. Thirdly, heterogeneity analysis indicates that the impacts of the low-carbon city pilot policy differ across various regions. Resource cities, eastern cities, as well as cities in the southeast and northwest regions, experience significant effects.
本研究以中国 204 个地级市 2010-2019 年的面板数据为基础，将低碳城市试点政策视为一项准自然实验展开研究。采用倾向得分匹配 - 双重差分模型（PSM-DID），分析了低碳城市试点政策对碳排放强度的影响效应。研究结果表明：第一，低碳城市试点政策显著降低了城市碳排放强度。第二，低碳城市试点政策降低城市碳排放强度的主要作用机制包括产业结构调整、能源消费管控和绿色技术创新进步。第三，异质性分析表明，低碳城市试点政策的影响存在区域差异，资源型城市、东部地区城市以及东南和西北地区城市的政策效应显著
