摘要
绿色是经济高质量发展的鲜明底色,而作为我国生态文明建设的重要举措,低碳城市试点有助于推动经济高质量发展。本文采用长江经济带2004-2020年108个城市市级面板数据,使用多时点双重差分模型,实证探究低碳城市试点对经济高质量发展的影响效应,研究发现:(1)低碳城市试点有利于提升长江经济带经济高质量发展水平,且政策效果具有滞后性,该结论在进行一系列稳健性检验后依旧成立;(2)异质性分析表明,从区位特征来看,低碳城市试点对长江上游地区经济高质量发展水平的提升效果更明显;从城市人口规模来看,低碳城市试点对人口规模较大城市的政策效果往往更明显;(3)机制分析表明,吸引外商直接投资是低碳城市试点促进长江经济带经济高质量发展的重要传导机制。
Green development is a defining feature of China’s high-quality economic,and as an important measure of China’s ecological civilization construction,low-carbon city pilot help promote high-quality economic development.Drawing upon panel data spanning 2004 to 2020,encompassing 108 cities within the Yangtze River Economic Belt,this article employs a sophisticated multi-time point difference-in-differences model to empirically explore the impact of low-carbon city pilot on high-quality economic development.The key findings underscore:(1)Low-carbon city pilot is conducive to improving the high-quality economic development level of the Yangtze River Economic Belt,and the policy effect has a lag.This conclusion is still valid after a series of robustness tests;(2)A nuanced analysis reveals heterogeneous impacts.Geographically,the low-carbon city pilot initiative exerts a more pronounced effect on promoting high-quality economic development in the upstream regions of the Yangtze River.Additionally,cities with larger populations tend to experience a more significant policy impact;(3)Mechanistic insights reveal that attracting foreign direct investment(FDI)constitutes a pivotal channel through which low-carbon city pilots facilitate high-quality economic growth in the Yangtze River Economic Belt.
