摘要: 为缓解中国农业用水短缺与污染状况,落实国家水安全战略和保证粮食安全,运用考虑非期望产出的SBM-Undesirable模型,比较研究了中国省际农业用水效率和农业用水优化路径。从全要素的角度出发,在识别主要影响农业用水效率因素的基础上,设计模型的投入指标并测算2011—2014年中国大陆31个省(区、市)的农业用水效率。结果表明,中国农业用水效率总体呈上升趋势,但仍然具有较大的提升空间,各个省(区、市)的农业用水效率呈现不同的发展趋势,新疆、江苏、广东等省份的农业用水效率提升空间大,具有很大的节水潜力。基于农业用水效率的实证结果和污染排放指标,对未达到农业用水效率有效前沿面的25个省份进行聚类分析,将25个省份的农业用水方式分为低农业用水效率-低污染排放、低农业用水效率-高污染排放类型、高农业用水效率-低污染排放类型和高农业用水效率-高污染排放类型四类,并分别提出了农业用水优化策略。

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
