【Abstract】 Land fragmentation means that the land used by every peasant household is divided into several pieces. The paper takes wheat and maize as examples to study the effect of land fragmentation on grain production. Normal production function model and frontier production function model are used to analyze the effect. The result indicates that land fragmentation decreases the scale effect and technological efficiency of grain production. It is estimated that arrangement policy of land will increase grain output.更多还原
