    摘要:

    [目的] 研究我国粮食主产区13个省份2001-2011年农业水资源利用效率,旨在明确各省份农业水资源利用效率提升的潜力。[方法] 采用DEA (数据包络分析)交叉评价模型。[结果] (1)2001-2011年我国粮食主产区农业水资源利用效率普遍偏低,且各省份之间的差异较为显著;(2)吉林、内蒙古、湖北、湖南、山东、辽宁和黑龙江省(区)属于"低投入低产出"类型,四川、河南、安徽、江西、河北和江苏省属于"高投入高产出"类型;(3)我国粮食主产区农业水资源利用效率整体处于"低投入低产出"阶段,农业水资源利用效率具有很大的提升空间。[结论] DEA交叉效率评价模型实现了对所有决策单元效率的完全排序和效率评价;虚拟决策单元的引入明确了研究区域内各单元农业水资源利用的提升潜力和改进方向。

    Abstract:

    [Objective] Studing the agricultural water utilization efficiency of 13 provinces in major grain producing areas from 2001 to 2011 in order to further clarify the improvement potential of agricultural water utilization efficiency.[Methods] By using DEA(data envelopment analysis) cross-evaluation model, the article took 13 provinces in major grain producing areas in China as the objects.[Results] (1) The efficiencies of agricultural water utilization were generally low from 2001 to 2011, and had significant differences among these provinces; (2) Provinces or autonomous regions of Inner Mongolia, Hubei, Jilin, Hu'nan, Shandong, Liaoning and Heilongjiang belonged to "low input and low output" type; provinces of Sichuan, He'nan, Anhui, Jiangxi, Hebei and Jiangsu belonged to the "high input and high output" type. (3) The efficiency of agricultural water utilization was overall in the "low input and low output" stage and has great improvement potentiality.[Conclusion] The DEA cross-evaluation performed well on the evaluation of utilization efficiency of all decision-making units; The potential utilization increments and ways of improvement were clarified by introducing virtual decision-making units.
