摘　　要：文章基于2006—2020中国30个省份数据量化评估减污降碳协同水平,通过Dagum基尼系数、空间马尔可夫链等方法分析减污降碳协同水平的时空演变趋势,实证检验了绿色技术创新对减污降碳协同水平的影响。研究发现:①中国减污降碳协同水平整体呈上升趋势,存在“俱乐部收敛”现象,全国及三大区域减污降碳协同水平的空间差异均表现为下降态势。②绿色技术创新具有显著的减污降碳协同效应,环境规制与政府财政支持在绿色技术创新对减污降碳协同水平的影响中起正向调节作用。③能源消耗强度揭示了绿色技术创新影响减污降碳协同水平的机制途径,环境规制和政府财政支持分别在此影响路径上起负向与正向的调节作用。④异质性分析表明,中西部地区绿色技术创新对减污降碳协同水平具有显著的促进作用,东部地区绿色技术创新的作用不显著。This study quantitatively evaluates the coordination level between pollution reduction and carbon reduction in 30 provincial-level regions in China from 2006 to 2020.It analyzes the spatiotemporal evolution trend of this coordination level using the Dagum Gini coefficient and spatial Markov chain.Additionally,it empirically tests the impact of green technology innovation on the coordination level between pollution reduction and carbon reduction.The research findings are as follows:1)The overall trend of the coordination level between pollution reduction and carbon reduction in China is increasing,exhibiting a"club convergence"phenomenon.The spatial difference of the coordination level between pollution reduction and carbon reduction shows a downward trend in China and three major regions.2)Green technology innovation plays a significant role in enhancing the coordination level between pollution reduction and carbon reduction,while environmental regulation and government financial support significantly enhance its promoting role.3)Energy consumption intensity reveals the mechanism of green technology innovation affecting the coordination level between pollution reduction and carbon reduction,environmental regulation and government financial support play negative and positive regulatory roles on this impact mechanism,respectively.4)Heterogeneity analysis reveals that green technology innovation has a significant promoting role in the coordination level between pollution-carbon reduction for central and western regions,but not for eastern region.
