高质量发展视角下碳排放权交易政策对城市生态福利绩效的影响

坚持生态优先,推进环境规制,对城市高质量发展具有重要意义。基于高质量发展理念,构建城市生态福利绩效(UEWP)评价框架,采用Super-SBM模型测度2010～2019年我国253个城市经济发展质量,并采用双重差分模型构建中国碳排放权交易政策(CETP)的准自然实验,测度碳排放权交易政策的实施对城市生态福利绩效的影响及作用机制。结果表明:我国城市生态福利绩效呈现东部地区高、西部地区低、中部地区最低的分布格局,并整体呈波动上升趋势; 碳排放权交易政策的实施可以有效提升城市生态福利绩效,但存在城市类型和地理区位的异质性,该推动作用主要存在于中心城市和中部地区城市; 此外,碳排放权交易政策的实施能够显著推动产业结构优化,并对城市生态福利绩效产生积极影响,但未激发区域波特效应的产生。

Impact of Carbon Emission Trading Policy on Urban Ecological Well-being Performance from the Perspective of High-quality Development

Promoting environmental regulation and the reduction of carbon emissions are the key path to guide the high-quality development. Based on the concept of high-quality development, a framework for evaluating the urban ecological well-being performance(UEWP)was constructed, the quality of economic development of 253 prefecture-level cities in China from 2010 to 2019 was measured using the Super-SBM model, and a quasi-natural experiment of China's carbon emissions trading policy(CETP)was constructed using differences-in-differences(DID)model, in order to measure the impact and effect mechanism of the implementation of CETP on the UEWP. The results show that the average values of UEWP in China show a distribution pattern of being higher in the eastern region, lower in the western region and lowest in the middle region; the overall trend of UEWP is fluctuating upward; CETP has significantly improved UEWP; urban heterogeneity tests illustrate that CETP plays more significant role in promoting UEWP of cities in the middle region and the central cities. CETP can advance industrial structure upgrading, thereby promoting UEWP; however, there is no evidence that CETP can stimulate the regional Porter effect.
