Study On The Influence Of Direct Grain Subsidy Policy On Total Factor Productivity Of Rice

Without agriculture,there will be instability,and without food,there will be chaos.Food security has always been at the core of strong agriculture and national security.In the context of resource rigidity tightening,it is increasingly important to improve the Total Factor Productivity(TFP)of rice in ensuring food security.Rice is the main food variety for more than 60%of Chinese population,and its production security and sustainable high quality development have become the priority among food security.Direct food subsidy,as the only "green box" subsidy policy recognized by the United Nations,has been in the process of reform and optimization since its implementation.To improve the quality of food production,especially rice production,has become an important part of the reform direction of direct food subsidy policy.Based on induced technology innovation theory,peasant household behavior theory and neoclassical economic growth theory,this study took rice production as an example,used panel data of 23 provinces from 2004 to 2020,adopted the output-oriented FP index method to measure rice TFP and analyze its growth source.On this basis,the Tobit regression model was constructed,and the substantial effects of China’s direct grain subsidy policy on rice TFP were empiricately analyzed under the premise of controlling human capital,development level,economic scale,cultivated land quality,price factors and natural factors.In order to provide alternative path selection and decision reference for policy effect evaluation policy optimization reform path and improvement of rice and even high quality development level of grain production.The results showed that:(1)From the productivity measurement results,China’s rice TFP still has great potential to increase.After the implementation of the subsidy policy,on the one hand,rice TFP only increased slightly,and even decreased in some years.On the other hand,the regional heterogeneity of rice TFP was significant,and the regional disparity showed a decreasing trend.(2)From the regression results,since the implementation of direct grain subsidy policy,it does have a positive effect on rice TFP,but the increasing effect is relatively small,and its effect is weakened year by year.The subsidy variable value in the eastern rice production area was the highest and was significant at the significance level of 0.01,followed by the western rice production area and was significant at the significance level of 0.05,while the central rice production area was the lowest and was not significant.(3)From the perspective of control variables,the average years of schooling,urbanization rate and per capita GDP all had a positive and significant impact on rice TFP,while the per capita disposable.income of rural residents and the-selling price of main products per 50kg had a significant negative impact on rice TFP.The effective irrigated area and disaster rate had negative but not significant effects on TFP.In conclusion,the TFP level of rice in China is poor,so the linkage mechanism of rice production cost and subsidy needs to be established.Attaching importance to the role of science and technology and increasing subsidies for technology popularization;Subsidies should be made according to local conditions and exchanges and cooperation between regions should be strengthened...
