中文摘要：

以对江西省新建县、渝水区、丰城市、鄱阳县、东乡县五个地区家庭农场调查数据为基础,基于投入导向的DEA分析法对家庭农场的经营效率进行测算,在此基础上,进一步通过建立Tobit回归模型分析了家庭农场经营效率的影响因素。研究结果表明：家庭农场经营综合效率的大小较多地依赖规模效率,土地的适度规模已成为促进家庭农场经营有效率的关键因素,家庭农场纯技术效率水平比较低;家庭农场的劳动力数量、投资规模、土地流转成本、农用机械数量、借贷资金、农用机械补贴和是否需要农业保险等因子对家庭农场的经营效率产生了显著影响。建议政府需要对家庭农场给予政策导向,完善土地制度以及健全农业社会化服务体系。

英文摘要：

The operational efficiency of family farms is calculated by input-oriented DEA method based on a survey of five major areas,namely,Xinjian County,Yushui District,Fengcheng City,Poyang County and Dongxiang County in Jiangxi Province,on the basis of which,the influencing factors of operational efficiency of family farms are analyzed by Tobit model based on the value of operational efficiency of family farms.The results show that the size of comprehensive efficiency greatly depends on scale efficiency and that the appropriate scale management of rural land has been a critical factor in enhancing operational efficiency of family farms.In addition,the pure technical efficiency has remained at a relatively low level.The study result shows that the operational efficiency is significantly affected by the quantity of labor force,the scale of investment,the cost of land circulation,the number of agricultural machinery,loan fund,the subsidies of agricultural machinery and agricultural insurance. Therefore,the government should make great efforts to provide policy support to family farms and improve and perfect the land system.What is more,it should do its best to improve the agricultural socialized service system.
