中文摘要：

研究目的：分析家庭劳动分工视角下耕地转入对农户耕地利用效率的影响。研究方法：用分工与专业化理论提出假设,用随机前沿生产函数进行实证估计。研究结果：（1）专业型农户耕地转入率为76.39%,远高于不完全分工型和完全分工型农户;（2）耕地利用技术效率随农户家庭分工演进有明显的变化,专业型农户耕地利用效率高于完全分工型农户,不完全分工型农户耕地利用效率最低;（3）农户耕地转入比例的提高对耕地利用效率具有一定的促进作用,但当其经营耕地总规模超过2.00 hm2时,耕地利用效率开始降低。研究结论：（1）通过城乡劳动力市场的统筹发展可促进农户家庭专业化分工及提升耕地利用效率;（2）在推进农业规模化经营过程中应保持适度经营规模。

英文摘要：

The purpose of the study is to analyze the impact of labor division and farmland transfer-in on farmland use efficiency. The research methods were the theory of labor division and specialization, and empirical analysis with stochastic frontier function. The research shows that： 1 ）Farmland transfer-in rate of professional rural householdis 76.39%, much higher than that of the rural household of non-perfect division and complete division. 2）Technology efficiency of farmland use has evident variation with rural households＇ labor division evolution; farmland use efficiency of professional rural households is higher than complete division ones; incomplete division rural households have the lowest farm land use efficiency; 3） Increasing ratio of farmland transfer-in plays a certain role in farmland use efficiency, but when the farmland scale exceeds 2.00 hm2, the farmland use efficiency then reduces.It is concluded thatl ） it could improve specialized division of rural household and farmland use rate through improving rural-labor market construction and strengthening rural labor professional training. 2） It should keep appropriate scale in the process of promoting agricultural scale management.
