Research On The Efficiency And Its Family Influencing Factors Of Rural Households' Farmland Management Scale

With the development and perfection of the Chinese market economic system, the stimulation effect of household contract responsibility begins to be weakened. Under the land equalization system, the small management scale are increasingly becoming an obstacle to the development of agriculture, village and farmers' income increase. Furthermore, it has been agreed by the theoretical research and practical exploration that the moderate scale management of farmland should be conducted through land transference. Meanwhile, the unsuccessful experience of farmland scale management during recent 20 years in China shows that, carrying out farmland scale management blindly couldn't achieve the substantial progress. Thus, before the farmland scale management is carried out, it is very important that the relationship between farmland scale and efficiency as well as its change law should be made a clear understanding.The research thought of this paper shows as follows:Based on the document reading, it defines the cocept as well as the scope of farmers' farmland management scale efficiency, meanwhile, domestic and foreign research situation about farmland management scale efficiency is explained. After introducing the two-step analytic technique of efficiency and influence factor which is based on DEA-Tobit, it establishes the family influencing factors regression model and farmland scale efficiency evaluation model. Besides, according to statistical data, it conducts a practical study about the change law of farmland management scale efficiency and family influencing factors in Linhe District, Bayannaoer City of Inner Mongolia Autonomous Region. The research content and conclusion of this paper shows as follows:First of all, on the basis of BCC (VRS) model, the input-output indexes are chosen according to the theory of input-output, and then, under the micro production target farmland scale efficiency evaluation model is established as well.Secondly, through the practical analysis of Linhe District, it concludes that the relationship between scale and efficiency of farmland management is not positive or negative correlationship, within the certain range, farmland scale efficiency will present U-shape change law with the increase of farmland scale efficiency, in addition, in the light of relative efficiency and optimum efficiency, it concludes that the optimum scale with highest efficiency of the household in Hetao Plain is an area of 80 to 90 mu.Thirdly, based on the DEA efficiency evaluation value, it calculates the family factors that affect farmers' farmland management scale efficiency through Tobit regression model. Finally, the metering result shows that there are seven remarkable influencing factor as follows:the age of household head, the quantity of farmland transference, the main occupation of household head, planting areas for vegetables, the labor used in agriculture, pieces of farmland, charges for machine work, areas of grain, and their interaction mechanism are explained at the same time.
