农田水利设施供给效率问题已成为当前政府及其公共管理领域在实现公共服务均等化过程中需关注和解决的重要问题.利用2007—2014年的统计数据,采用以产出为导向的三阶段DEA模型,对中国29个省份的农田水利设施供给效率进行测算和分析.研究表明,环境因素和随机因素对中国农田水利设施供给效率产生一定的影响,由于其影响,中国农田水利设施供给效率被低估;在剔除其影响后,中国农田水利设施供给效率水平得到提升,但总体水平仍偏低(平均技术效率水平为0.668);农田水利设施供给效率在不同区域存在差异,即中部地区>西部地区>东部地区;各省之间的农田水利设施供给效率水平更加集中,呈逐渐收敛趋势;农田水利设施供给效率受到人均GDP、财政分权度、农民受教育程度、农民收入水平、人口规模、城市化水平、地理区位等因素的影响.%Supply efficiency of irrigation and water conservancy facilities has become an important issue which calls for not only attention but also solution in the equalization of public service in the field of public management.Based on the statistical data from 2007 to 2014,the three-stage DEA model of output oriented model is used to calculate and analyze the supply efficiency of irrigation and water conservancy facilities of 29 provinces in China.The results show that environmental factors and random factors have a certain impact on supply efficiency of irrigation and water conservancy facilities,resulting in the supply efficiency of irrigation and water conservancy facilities being underestimated.After eliminating its influence,the supply efficiency of ir-rigation and water conservancy facilities has been improved,but the overall level remains low(average technical efficiency level is 0.668).Region differences can be ranked in terms of such efficiency in the order of the central region,western region and eastern region.The supply efficiency of irrigation and water conservancy facilities is more concentrated among provinces,which shows a gradual convergence trend.The supply efficiency of irriga-tion and water conservancy facilities is affected by per capita GDP,fiscal decentralization,farmers' education level,farmers' income level,population size,urbanization and geographic location.
