环境效应和随机误差的农户家庭经营技术效率分析——基于三阶段DEA模型和我国农户的微观数据

为了排除环境效应和随机误差对效率值的影响,文章尝试在国内运用三阶段DEA模型和农户生产调查数据,对2008年我国农户家庭经营技术效率进行了实证分析.研究结论为:农户的生产技术效率确实受到平均受教育年限、农户到最近农产品贸易市场的距离、良种补贴数额、人均家庭纯收入等环境变量和随机因素的影响.在同质经营环境和经营运气的条件下,农户生产决策与管理效率并不低下,且区域间差异较小,但规模效率成为制约技术效率提升的瓶颈.在此基础上,文章提出了通过各种手段扩大农户种植规模、加大农民技术培训力度、重构农村技术推广服务系统、建立健全各种农业信息流通渠道、引导农民合理利用国家良种补贴等政策建议.

The Study of Technical Efficiency of Rural Household Management with Environmental Effects and Random Error——Based on a Three-stage DEA Model and the Micro-data of China's Rural Households

In order to eliminate the impacts of environmental effects and random error on the technical efficiency,the paper makes an empirical study on the technical efficiency of rural household management in 2008 through a three-stage DEA model and the survey of rural household production.Studies show that the technical efficiency of rural households has been affected by random factors and environmental variables,such as the average education years,the distance between houses of rural households and the nearest agr...
