摘　　要：推动长江经济带绿色高质量发展,应严格控制水资源耗费总量及强度,提升用水效率与降低水污染排放,并加强跨域水资源优化配置与水污染协同治理。本文以长江经济带11省市为研究对象,以GDP与废水排放量分别作为合意产出与非合意产出,采用SE-SBM模型对2005—2017年长江经济带的省际用水效率进行测度,重点考察用水效率、环境规制、FDI集聚、二者交叉项的空间相关性,并采用空间与时间双固定的SDM模型,检验省际用水效率及环境规制、FDI集聚等驱动因素的空间溢出效应。用水效率结果显示,经济带用水效率整体上呈现先下降后上升U型趋势,但中西部一些省份用水效率一直处于下降趋势;省际用水效率呈现东西中部各省市阶梯下降,且整体上呈现先趋同后不断扩大的趋势,仅中部省份用水效率呈现趋同趋势。空间溢出检验显示,用水效率与环境规制、用水效率与FDI集聚在大多数年份呈现显著空间相关性;环境规制、环境规制与FDI集聚的交叉项、工业化存在显著的负向效应,城镇化、技术创新、地区发展水平存在显著正效应;环境规制、环境规制与FDI集聚的交叉项、城镇化、工业化、外贸依存度正向溢出显著,技术创新负向溢出效应显著。应严格控制水资源消耗与水污染排放,制定科学合理且标准统一的环境规制,推动新型城镇化建设与产业转型升级,引导FDI合理集聚与技术溢出,严格限制各省区逐底竞争与以邻为壑,规范长江经济带产业梯度转移。To promote the green and high-quality development of the Yangtze River Economic Belt,the government should strictly control the total consumption and intensity of water resources,improve water utilization efficiency,reduce water pollution emissions,and strengthen the cross-region optimal allocation of water resources and coordinated water pollution control.This paper took 11 provinces and cities of the Yangtze River Economic Belt as the research object,with GDP and wastewater respectively as desirable output and undesirable output.The SE-SBM model was adopted to measure provincial water efficiency along the Yangtze River Economic Belt from 2005 to 2017.Focused on the spatial correlation of water utilization efficiency,environmental regulation,FDI agglomeration,the cross terms,this paper also used SDM model with dual fixed space and time to test provincial water utilization efficiency and environmental regulation,the spatial spillover effects of FDI agglomeration and other driving factors.The results of water utilization efficiency showed that the water utilization of the Yangtze Economic Belt showed a U-shaped trend of first decreasing and then increasing as a whole,but the water utilization of some provinces in central and western China was in a declining trend.The inter-provincial water utilization decreased in the provinces from the east to the middle to the west.The Inter-provincial differences trend was first convergence and then expansion on the whole,while the water utilization in the central provinces showed a trend of convergence.The spatial spillover test showed that there was a significant spatial correlation between water utilization and environmental regulation,water utilization and FDI agglomeration in most of years.There were significant negative effects on environmental regulation,the cross term of environmental regulation,FDI agglomeration and industrialization.There were significant posltive effects on urbanization,technological innovation and regional development level.There were significant po
