黄土高原退耕还林前后农户农业生产效率DEA分析--以退耕还林示范县吴起县为例

Study of the Efficiency of Agricultural Production of Pre & Post-Rehabilitating Plough to Forest (Grassland) in the Loess Plateau Based on DEA Method——Based on Wuqi County in Shaanxi Province

运用DEA分析方法,以陕西省吴起县为例,测算了黄土高原地区退耕还林前后农户农业生产效率的变化,表明该地区在退耕还林(草)后,农业规模收益处于递增阶段,规模效率呈波动性变化,技术效率与综合效率变化一致,呈提高趋势,但综合效率有效性仍不足。为了确保退耕还林(草)工程已取得的绩效,可以通过调整土地资源配置、农业人力资源配置和充分合理利用投入的农用物资来提高农业生产效率,并得出相应的结论。

The paper used DEA method to calculate the efficiency of agricultural production of pre ＆ post-Rehabilitating Plough to Forest（Grassland） in WU Qi County, Shaanxi Province. The results showed that agricultural scale income is on the increasing stage, technology efficiency and comprehensive efficiency are improved, but the efficiency is still insufficient. In order to maintain the performance of Rehabilitating Plough to Forest （Grassland） projects, households or relevent goverment must adjust the allocation of land resources, agricultural human resource allocation and adequate and reasonable use of the agricultural input materials to enhance agricultural production efficiency ,finally, corresponding conclusions have been drawn.
