Abstract

Abstract: To alleviate agricultural water shortage and pollution and ensure food security, this paper use the SBM-Undesirable model to estimate the agricultural water use efficiency for China’s 31 provinces from 2011 to 2014. Some conclusions are as follows：During research period, the agricultural water use efficiency in China is rising,but still has a large space to improve.The trend of efficiency of different provinces is various and Xinjiang,Jiangsu and Guangdong have great water-saving potential.Then we cluster 25 provinces which are not achieving the effective frontier into four categories by clustering analysis. Respectively,the optimization strategy of agricultural water are put forward.

Key words: undesirable outputs, agricultural water use efficiency, water-saving potential, SBM-Undesirable model, cluster analysis
