Does Agricultural Subsidy Improve Technical Efficiency of Grain Production?An Empirical Study Based on the Data of 552 Grain Production Family Farms in Jiangsu Province
Based on the micro-survey data of 552 family farms in Jiangsu Province,the effects of agricultural subsidies on grain production technical efficiency were empirically analyzed by using the trans-logarithmic stochastic frontier production function and technical efficiency loss function based on measuring grain production technical efficiency of family farms.The results show that the average technical efficiency of grain production on family farms in Jiangsu province is 0.809,and there is a loss of technical efficiency of 19.1% in the actual production process of family farms. Compared with machinery and self-owned labor,the output elasticity of the input factor of agricultural capital is the largest.Subsidies have a significant negative impact on the technical efficiency of food production on family farms.The results of grouping regression shows that the technical efficiency increases with growing scale of operation,and there is a significant scale difference in the impact of subsidies on the technical efficiency of grain production.In order to promote the healthy development of family farms,we should pay attention to promoting the transformation and upgrading of grain production technology,prioritize subsidy payment,adopt diversified and flexible subsidy methods,improve the orientation,precision and effectiveness of subsidies,and give full play to the role of subsidies in promoting the technical efficiency of grain production.
