The Impact Of Land Transfer On Food Productio

For a long time,promoting rural land transfer and achieving moderate scale agricultural operations has been generally regarded as a necessary condition for increasing grain production in China.However,recently,along with the gradual promotion of rural land transfer,the growth rate of China’s grain production has declined significantly.This is obviously contrary to the original analysis logic of grain production increase,creating difficulties in the perception of grain production and grain security.To this end,this paper studies the impact of rural land transfer on agricultural management modes and on grain production,logically and consistently explains the phenomena of rural land transfer,agricultural scale operations and the decline in grain production growth in terms of both unit yield of grain crops and grain cultivation area,which will be of great significance to China’s grain security and agricultural modernisation.The empirical facts of rural land transfer and grain production show that: the rural land transfer promotes the transformation of the main body of farmland farming from small farmers to family farms,promotes the scale and specialization of farmland farming,and can effectively improve the unit yield of grain crops,which is an important reason for the growth of grain output;However,rural land transfer also manifests the cost of farmland rent,under the condition of "low profit from growing grain",it is easy to lead to the "non-grain" cultivation of a large amount of farmland,which will reduce the cultivated area of grain crops,thereby causing a decline in grain output;If the influence of the latter is greater,it will inevitably lead to a decline in the growth rate of grain production.Based on data from the China Labor-force Dynamic Survey(CLDS)in 2014,2016 and2018,this paper uses fixed-effects models,instrumental variables methods,mediated utility models and multivariate delta methods to test the impact of land transfer on grain production,and to verify the mediating effect of unit grain crop yield and grain production cultivated area.The results show that land transfer significantly reduces grain yield,unit grain crop yield and grain production cultivated area play an important mediating role,and the mediating role of grain production cultivated area is greater.In addition,from the two aspects of farmland cultivation scale and farmland cultivation specialization,this paper examines the decisive role of land transfer on the unit grain crop yield;from the two aspects of the increase in farmland rent and the decline in the income of grain cultivation,the negative impact of land transfer on the cultivated area of grain crops is also tested.Through theoretical analysis and empirical test,this paper proves the inhibitory effect of rural land transfer on grain output growth.However,this does not mean that rural land transfer must stop.First,the moderate scale of farmland management is the inevitable result of the development of industrialization and urbanization,which is irresistible;Second,the large number of non-agricultural transfer of agricultural labor has resulted in frequent occurrence of idle tillage and abandoned tillage,land transfer can reduce this phenomenon,increase grain output and promote farmers’ income;Third,the "non-grain" of agricultural land cultivation is the main reason for the decline in grain production,the government can alleviate the trend of "non-grain" cultivation of agricultural land through relevant agricultural policies and grain policy reforms,thereby reversing the negative impact effect of land transfer on grain production.Therefore,in order to guarantee the security of grain production in China,this paper puts forward relevant policy recommendations in terms of "strictly control the use of rural land to ensure the area of grain cultivation","developing moderate scale agricultural operations and improving the efficiency of grain production","increasing support for grain production and effectively increasing the income from grain cultivation","improving agricultural risk prevention and response policies to effectively protect the interests of farmers" and "stabilising the relationship between rural land contracts and continuing to give full play to the enthusiasm of small farmers in growing grain".
