中文摘要：

对农业效率与农户规模负向关系的研究一直是农业经济学的热点，本文以1999-2003年湖北农户数据为证据，从土地生产率、劳动生产率、成本利润率、TFP和技术效率等角度，多维度检视农户效率与农户规模的关系，从家庭禀赋角度对农户效率的影响因素进行实证。农业效率与农户规模负向关系假说需要放到更宽阔的视野内全面审视，小农户是否享有相对大农户的效率比较优势取决于宏观导向上优先考虑的政策目标。通过各种政策工具提高农业效率的潜力巨大，可以妥善利用。

英文摘要：

Study on the Inverse Relationship between farm＇s efficiency and farm size is always a hot topic in the agricultural economics. Using the farm-level micro panel data from Hubei province in 1999-2003, the paper, from the multi-perspectives of the land productivity and labor productivity etc. , discusses the relationship between farm＇s efficiency and farm size, and analyzes the effects of rural household endowments on the farm＇s efficiency. An o- verall look in a broader vision should be given to the hypothesis of the Inverse Relationship. Whether the small-sized farm, compared to large-sized one, enjoys the efficiency＇s comparative advantages depends on the top-priority policy goals. The policy instruments by which could greatly improve the farm＇s efficiency can be applied appropriately.
