摘要
环境规制是否能够通过重塑工业集聚格局的途径影响城市碳排放强度?本文以全国282个地级及以上城市为考察对象,测算了样本城市2003—2017年碳排放强度的变化情况,并探讨环境规制对城市碳排放强度的直接影响和间接影响。结果表明:环境规制有力地抑制了城市碳排放强度增长,这一结论在替换指标后依然稳健;中介效应分析结果表明,环境规制虽然促进了城市工业集聚,但工业集聚显著提升了城市碳排放强度,一定程度上"遮掩"了环境规制对城市碳减排的积极影响;异质性分析结果表明,环境规制和工业集聚对城市碳排放强度影响程度存在明显的区域差异。进一步加强环境规制力度、出台更加灵活的环境政策、引导工业部门有序集聚有助于抑制城市碳排放强度,促进中国低碳经济健康发展。
Can environmental regulations affect the intensity of urban carbon emissions by reshaping the industrial agglomeration pattern?This paper takes 282 cities at prefecture-level and above across China as the object of the study,measures the changes in carbon emission intensity of sample cities from 2003 to 2017,and discusses the direct and indirect impacts of environmental regulations on urban carbon emission intensity.The results show that environmental regulation has effectively curbed the growth of urban carbon emission intensity,and this conclusion is still robust after replacing the indicators.The analysis of mediation effect shows that although environmental regulation promotes urban industrial agglomeration,industrial agglomeration significantly increases the intensity of urban carbon emissions,and thus to some extent"masks"the positive impact of environmental regulation on urban carbon emission reduction;Heterogeneity analysis results show that there are obvious regional differences in the impact of environmental regulations and industrial agglomeration on urban carbon emission intensity.Further strengthening environmental regulations,introducing more flexible environmental policies,and guiding the orderly agglomeration of industrial sectors will help curb the intensity of urban carbon emissions and promote the sound development of China’s low-carbon economy.
