摘要：In this paper, through the actual investigation of the production and operation in the main grain producing areas, the authors collected data from 89 farms in Northeast China. This paper first describes the individual characteristics of the family farm operators, the size of the land and the circulation of the farm, the situation of the farm to obtain funds and information services. Then we estimate the development efficiency based on the DEA model, by using the survey data. The results show that family farm business process is lack of new agricultural technologies; family farmers' management ability is weak, the factors of production inputs such as unreasonable causes share of the family farm in Northeast DEA efficiency is low. In order to develop the efficiency of the family farm, government should put forward and optimize the land circulation system, pay attention to the quality of the family farmers, and improve the agricultural technology extension system, optimize the allocation of production factors.
