Farmland transfer is a critical step of adapting urbanization development agricultural modernization and farmer’ benefits realization.Through farmland transfer to centralize lands,promote the land scale and efficiency of resource allocation,and improve the comparative benefit,the requirements of rural labor force transfer and the provision of agricultural products derived from the development of economic society,especially the object of food safety,can be fulfilled.So advancing farmland transfer is become an important work arrangement of issues relating to agriculture,rural areas and rural people in the first policy documents of recent years in China.However,with the expansion of the farmland transfer,the "non-grain" and "non-agricultural" phenomena appeared in the transfer.The use change of agricultural land after the land transfer not only threatens the production of grain,but also may lead to a thorough damage to the long-term agricultural production capacity,which is contrary to the original intention of the agricultural land circulation.Therefore,how to solve the problem of "non-grain" and "non-agriculture" in the farmland transfer,to promote function of the farmland transfer in food safety and the agricultural production is an issue that is worthy of attention and research.On the basis of the previous studies on the agricultural land circulation and the "non-grain" and "non-agricultural" problems,the paper makes a further distinction between "non grain" and "non agriculture" in agricultural land transfer.Under the premise of realizing the status quo of "non grain" and "non agriculture" in the farmland,the differences of "non grain" and "non agriculture" in the interest demands,the main behaviors and the impact on food security are analyzed.Then,according to the statistical yearbook data,the paper calculate the loss of grain production of the whole country from 2009 to 2015 and all provinces in 2015,and analyze the reasons of "non grain" and "non agriculture".The paper analyses the behavior mechanism of "non farming" of farmers in the circulation of farmland and uses the dual structure of peasant with different capacity and different land scale to analyze the choice differences between the farmers in different types.It is found that grain-plant-only farmers would reduce labor input in grain cultivation under the premise of meeting the demand of grain rations,and large households that plant more than one crop show more obvious "non grain" inclination.Compared with the farmers with small scale land,the farmers with large scale land are more willing to engage in non grain production.From the model,the reason of "non grain" is that the lower comparative benefits of grain planting than that of non grain crops.On this basis,the paper analyses the situation and reason of family farm’s non-grain selection.Relatively low comparative efficiency of grain,small scale farmland in transaction,vague law about farmland use and unfulfillment of food subsidies and policy support and other factors lead to "abandoning the grain and plant economic crops".In the end,in terms of the "non-grain" and "non-agricultural" phenomenon in the farmland transfer,the following suggestions are provided: exerting the comparative advantage of the major grain producing areas,adhering to area of arable land and realizing the resource flow in the production and marketing areas,improving the comparative benefits of grain production,adjusting the structure of agricultural production,promoting land reclamation and high standard farmland construction and standardizing the government behavior in farmland circulation policy,so as to prevent the "non-grain" and "non-agricultural" risk of the agricultural land transfer,achieve the goal of national food security and guarantee the rights and interests of the farmers in the agricultural land transfer. |
