摘　　要：利用2006-2020年全国23个省市区的面板数据,采用面板分位数模型,研究粮食直接补贴的全要素生产率效应及其时空差异。结果显示:我国水稻全要素生产率整体呈增长态势,且技术进步为增长主要来源;粮食直接补贴对各分位点水稻全要素生产率的影响系数均为负,但低水平的负面影响更显著;观察期内,粮食直接补贴对水稻全要素生产率的影响系数在“十三五”时期由负转为正;粮食直接补贴对不同经济发展水平地区的影响存在差异,东北地区具有正面影响。据此,建议重视水稻生产技术进步,并持续改革和优化粮食直接补贴政策,未来相关政策增量资金可向东北地区倾斜,促进我国粮食生产高质量发展与粮食安全。With panel data from 23 Chinese provinces(cities and districts)from 2006 to 2020,a panel quantile 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 productivity turn from negative to negative in the 13th Five-Year Plan period.The impact coefficient of direct grain subsidy 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 future,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.
