摘　　要：运用DEA方法测算出中国13个粮食主产区2000—2012年的农业生态效率,并运用Malmquist指数方法进行动态分析。结果表明,2000—2012年中国粮食主产区农业生态效率均值仅为0.928,只有6个省份的投入产出达到最优水平,其余省份的生产资源投入存在一定程度的效率损失。从2000和2012年的对比分析来看,辽宁、内蒙古、江苏、湖北、湖南和四川的农业生态效率一直保持较高水平,河南、河北、山东和安徽则都处于非DEA有效状态。从动态分析结果来看,虽然中国粮食主产区农业生态效率整体呈上升趋势,但农业生产技术进步和综合技术效率损失并存,技术进步、纯技术效率和规模效率是影响农业生态效率的主要因素。The paper applies DEA method to measure the agricultural eco-efficiency of 13 major grain-producing provinces from 2000 to 2012, and then makes a dynamic analysis using Malmquist index method. Results show that the average value of agricultural eco-efficiency in major grain-producing areas is only 0.928 from 2000 to 2012. Only 6 provinces have reached the optimal level of the input-output ratio in the agricultural production process. There is a certain degree of efficiency loss of production resources input in the remaining provinces. The agricultural eco-efficiency of Liaoning, Inner Mongolia, Jiangsu, Hubei, Hunan and Sichuan has always been maintained at a higher level from the comparative analysis of 2000 and 2012. Henan, Hebei, Shandong and Anhui were in a non DEA state. Judging from the dynamic analysis results, the agricultural eco-efficiency of the main-grain producing areas shows a rising trend in the past 13 years, while the technology progress and comprehensive technical efficiency losses exist at the same time. Technology progress, pure technical efficiency and the scale efficiency are the main factors which influence agricultural eco-efficiency.
