摘　　要：科学地评价我国水资源利用效率的地区差异,对推进社会可持续发展具有重要意义。将水足迹作为投入指标纳入水资源利用效率的分析框架之中,提出Shephard水资源距离函数,并依据2009—2018年我国大陆30个省份(西藏除外)的面板数据,运用基于Shephard水资源距离函数的随机前沿分析模型对我国区域的水资源利用效率及其影响因素进行了实证分析。结果表明(:1)在研究期间,我国水足迹总量及其年增长率均有较大的波动,我国各省份的水足迹总量之间的差异较为明显(;2)东部、中部、西部的水资源利用效率存在显著差异,呈现出自东向西依次递减的区域分布特点(;3)经济发展水平与水资源利用效率呈正相关,水资源禀赋、城镇化进程和产业结构(第三产业比重)均与水资源利用效率呈负相关。研究结果有利于探寻促进我国水资源可持续利用和统筹协调发展的有效途径。Scientific evaluation of the differences between China’s water resource utilization efficiency is of great significance to the promotion of social sustainable development.Incorporating water footprint as an input indicator into the analysis framework of water resource utilization efficiency,a Shephard water resources distance function is proposed,and based on panel data of30 provinces(excluding Tibet) in Chinese mainland from 2009 to 2018,using the stochastic frontier analysis model based on the Shephard water resources distance function,an empirical analysis of the regional water resources utilization efficiency and its influencing factors in China.The results show:(1) During the study period,China’s total water footprint and its annual growth rate fluctuated greatly,and the difference between the total water footprint of each province is obvious.(2) There are obvious differences in water use efficiency in the east,middle and west,showing the regional distribution characteristics of decreasing from east to west.(3) The level of economic development is positively correlated with water resource utilization efficiency,and water resource endowment,urbanization process and industrial structure(the proportion of the tertiary industry) are all negatively correlated with water resource utilization efficiency.The results of the research are conducive to exploring effective ways to promote the sustainable use of water resources in China and overall planning and coordinated development.
