中国20世纪早期农户耕地面积与土地生产率关系研究--基于卜凯农村社会调查

The Relationship between Size and Land Productivity in early 20th Century China:Based on Buck Rural Social Survey

面积与土地生产率关系一直是农业发展进程中的争议话题之一。本文利用卜凯农村社会调查原始数据,以实证估计方法计算出小型、中小型、中型、中大型和大型农户的土地生产率差异,并验证了在传统农业中存在着耕地面积与土地生产率的负向关系,显现出"小农"优势。在分析不同规模农户的生产行为差异及外在劳动力市场特征的基础上,认为劳动力市场不完善是造成"小农"优势的根本,而家庭生产行为差异是其外在表现,并直接引发了耕地面积与土地生产率的负向关系。

The relationship between size and land productivity is one of the disputes in the process of agricultural development.Based on the original data of Buck rural social survey,this study calculated the productivity differences among small,small & median,median,median & large and large farms to verify ' small advantage',and explore the household behavior differences and labor market characteristics.It can be considered that imperfect labor market causes inverse size-productivity relationship primarily while household behavior differences are direct reasons.
