摘　　要：为探求效率尺度下的最优土地经营权结构,采用两阶段OLS法,基于东北地区的微观调查数据,分析土地转入率对种粮土地产出率的影响。结果表明:大户土地转入率与土地产出率两者呈倒“U”型关系,寻找工具变量、采用两阶段OLS进行估计后,相关结论仍然稳健;土地要素禀赋不同,农户的最优经营权结构不同,进而导致最优规模不同;现有技术及规模条件下,土地转入率的增加可提高大户土地产出率。In order to explore the optimal structure of land management right under the efficiency scale,based on the micro survey data of Northeast China,this study uses two-stage OLS method to analyze the impact of land conversion rate on grain yield of households.The results show that the relationship between large households’ land transfer rate and land output rate is inverted "U" type.After searching for tool variables and using two-stage OLS to estimate,the relevant conclusions are still robust.For different land factors endowment,the optimal management right structure of farmers is different,which leads to different optimal scale;under the existing technology and scale conditions,the increase of land transfer rate can improve the land output rate of large scale households,but its impact on ordinary scale farmers is not obvious.
