Effect of Direct Grain Subsidies on Total Factor Productivity:a Case Study of Rice
With panel data from 23 Chinese provinces(cities and districts)from 2006 to 2020,a panel quan-tile model is used to study the rice total factor productivity effect of direct grain subsidies and its spatial-temporal heterogeneity.The results show that:China's rice total factor productivity as a whole is growing,and technological progress is the main source of growth;the coefficients of direct grain subsidies on rice total factor productivity in each quartile are all negative,but the negative effect is more significant at low levels;the coefficients of the effect of direct grain subsidies on rice total factor productivity during the observation period turn from negative to negative in the 13th Five-Year Plan period;the coefficients of the effect of direct grain subsidies on rice total factor produc-tivity turn from negative to negative in the 13th Five-Year Plan period.The impact coefficient of direct grain subsi-dy on rice total factor productivity in the observation period turns from negative to positive in the 13th Five-Year Plan period;the impact of direct grain subsidy on regions with different levels of economic development varies,and it has a positive impact in the Northeast region.Accordingly,attention should be paid to the technological progress of rice production,and the direct grain subsidy policy should be continuously reformed and optimized;in the fu-ture,the incremental funding of the relevant policy could be tilted towards the northeastern region,so as to promote the high-quality development of China's grain production and the guarantee of food security.
