本文在分析中国各主要工业省区工业用水现状的基础上,选用随机前沿生产函数模型,利用13个主要工业省区1999~2013年的面板数据,测算每年的工业用水效率值,通过定额比较法计算工业节水潜力,并通过系统聚类方法将13个主要工业省区划分为3种节水潜力类型进行分析。分析结果表明：各主要工业省区的工业用水效率均未达到1,说明各省存在一定的节水空间,节水潜力较大;随着工业用水效率的不断提高,各省每年的工业节水潜力大体上呈逐年递减态势;各省区不仅工业用水效率存在差异,工业节水潜力也存在明显差异,其中,江苏和湖北的工业节水潜力较大,黑龙江、上海、福建和广东次之,其他省区工业节水潜力较小。

Based on the analysis of China＇s major industrial provinces industrial water status,selection of stochastic frontier production function model,using the panel data of 13 main industrial provinces during 1999- 2013,this paper calculates the annual industrial water efficiency value,through comparison method to calculate the quota of industrial water- saving potential,and through the system clustering method to the 13 main industrial provinces division for the 3 types of water saving potential analysis.The analysis results show that： the main industrial provinces of industrial water use efficiency were not reached 1,that every province has water saving space and great water- saving potential; with the continuous improvement of the efficiency of industrial water,industrial water saving potential in the provinces of year shows substantially decreasing trend; the provinces industrial water efficiency differences also exist,and the potential of water saving differences are among them; industrial water saving potential in Jiangsu and Hubei,Shanghai,Fujian is larger,while Heilongjiang,Guangdong,and other provinces industrial water- saving potential is lower.
