摘      要：In this study,we developed an evaluation index system for green total-factor water-use efficiency(GTFWUE)which reflected both economic and green efficiencies of water resource *** we measured the GTFWUE of 30 provinces/municipalities/autonomous regions(hereafter provinces)in China(not including Tibet,Hong Kong,Macao,Taiwan as no data)from 2000 to 2018 using a minimum distance to the strong frontier model that contained an undesirable *** further analyzed the regional differences and spatial correlations of GTFWUE using these values based on Global and Local Moran’s I statistics,and empirically determined the factors affecting GTFWUE using a spatial econometric *** evaluation results revealed that the GTFWUE differed substantially between the *** provinces with high and low GTFWUE values were located in the coastal and inland areas of China,*** eastern region had a significantly higher GTFWUE than the central and western *** GTFWUEs for all three regions(eastern,central,and western regions)decreased slowly from 2000 to 2011(except 2005),remained stable from 2012 to 2016,and rapidly increased in 2017 before decreasing again in *** found significant spatial correlations between the provincial *** GTFWUE for most provinces belonged to the high-high or low-low cluster region,revealing a significant spatial clustering effect of provincial *** also found that China’s GTFWUE was highly promoted by economic growth,population size,opening-up level,and urbanization level,and was evidently hindered by water endowment,technological progress,and government ***,the water-use structure had little impact on *** study fully demonstrated that the water use mode would be improved,and water resources needed to be used more efficiently and green in ***,based on the findings of this study,several policy recommendations were proposed from the aspects of cross-regional cooperation,econo
