摘　　要：基于改进的三阶段SBM-DEA模型对中国大陆除西藏外的30个省(区、市)工业用水效率进行评价,并利用泰尔指数探究全国工业用水效率的区域差异。研究结果表明:外部环境和随机干扰是不可忽视的重要影响因素,经济发展水平、环境规制、人均水资源量对提升工业用水效率有积极作用,工业化程度、对外开放程度表现为明显的负向抑制作用;修正后全国工业用水效率大幅提高且呈增长态势,区域工业用水效率由“东高中低”空间分布演化为“东高西低”,流域工业用水效率呈现为黄河流域效率大于长江流域的空间格局;低工业用水效率组省(区、市)数量最多,高工业用水效率组仅包括北京和天津;我国工业用水效率空间差异性有减小的趋势,为实现区域协调发展需重点关注东部地区和西部地区内部各省(区、市)工业用水状况。The improved three-stage SBM-DEA model is used to evaluate the industrial water use efficiency(WUE)of various provinces and cities in China,and the Theil index is used to explore the regional differences of the national industrial WUE.The results show that the external environment and random interference are the important influencing factors that cannot be ignored.The economic development level,environmental regulation and per capita water resources have positive effects on the improvement of industrial WUE,while the degree of industrialization and the degree of opening to the outside world have obvious negative inhibitory effects.After the revision,the industrial WUE in China increases significantly and shows an increasing trend.The spatial distribution of the regional industrial WUE changes from“high in the east and low in the middle”to“high in the east and low in the west”.The spatial pattern of the industrial WUE in the Yellow River Basin is higher than that in the Yangtze River Basin.The number of provinces in the low industrial WUE group is the largest,while the high industrial WUE group only includes Beijing and Tianjin.The spatial difference of industrial WUE in China has a decreasing trend.In order to realize the coordinated regional development,the industrial water use in the eastern and western China should be highlighted.
