摘　　要：为研究南水北调中线工程水源区环境规制通过水资源利用对区域发展质效的影响,基于2005—2022年南水北调中线工程水源区12个城市的面板数据,构建基准回归模型、中介效应模型和门槛效应模型,实证分析了环境规制、水资源利用效率和经济高质量发展之间的关系。结果表明:环境规制对经济高质量发展具有正向促进效应,该促进效应在不同区域间存在异质性,环境规制的促进作用在用水量小的地区更加显著,而在用水量大的地区,丰富的水资源限制了环境规制对经济高质量发展的促进作用;在环境规制影响区域,水资源利用效率在经济高质量发展过程中发挥出显著的中介作用,水资源利用效率中介效应占环境规制总促进效应的比例为13.5%;水资源利用效率在环境规制对经济高质量发展影响中具有门槛效应,当水资源利用效率超过4.3后,环境规制对经济高质量发展的促进效应显著增强。To study the impact of environmental regulations on regional development efficiency through water resources utilization in water source area of middle route of the South-to-North Water Diversion Project,baseline regression model,mediation effect model,and threshold effect model were constructed to empirically analyze the relationships between environmental regulations,water resources utilization efficiency,and high-quality economic development based on panel data of 12 cities in water source area of middle route of the South-to-North Water Diversion Project from 2005 to 2022.The results show that environmental regulations have a positive promoting effect on high-quality economic development,and the promoting effect is heterogeneous in different regions.The promoting effect of environmental regulations is more significant in areas with low water consumption,while in areas with high water consumption,the abundance of water resources restricts the promoting effect of environmental regulations on high-quality economic development.In the areas affected by environmental regulations,water resources utilization efficiency plays a significant mediation role in the process of high-quality economic development,and the mediation effect of water resources utilization efficiency accounts for 13.5%of the overall promoting effect of environmental regulations.Water resources utilization efficiency exhibits a threshold effect in the impact of environmental regulations on high-quality economic development.When the water resources utilization efficiency exceeds 4.3,the promoting effect of environmental regulations on high-quality economic development is significantly enhanced.
