摘　　要：文章基于非径向方向性距离函数和MGML指数考察中国粮食生产效率的变化趋势、内生增长潜力及提升来源,进而探寻促进粮食产业高质量发展的优化路径。研究结果表明:中国粮食生产效率总体水平不高,且在研究期内呈现“下降—稳定—上升”的三阶段演化特征,2020年距有效前沿仍有22.3%的提升空间;投入和非期望产出冗余是阻碍粮食生产效率提升的两个主要原因,面源污染、碳排放以及劳动力和机械投入过多均会带来一定程度的效率损失;2015年之前中国粮食生产效率提升主要依赖于技术进步,2015年之后技术效率和技术追赶发挥了较大作用;中国粮食生产效率下降的地区大都分布在秦岭—淮河以南以及边疆地区,且导致各地区粮食生产效率下降的原因有所差异,粮食主产区主要受制于技术退步,粮食主销区主要受制于技术效率低下,产销平衡区主要受制于自身技术水平与共同前沿越来越大的差距。Based on the non-radial directional distance function and MGML index,this paper investigates the trend,endogenous growth potential and improvement sources of China’s grain production efficiency,and then explores the optimization path to promote the high-quality development of grain industry.The results go as the following:China’s overall grain production efficiency is not high,and it is characterized by a three-stage evolution of“decline-stability-rise”during the sample period,still with 22.3%room for improvement from the effective frontier in 2020.Input and unexpected output redundancy are the two main factors that hinder improvement of grain production efficiency.Non-point source pollution,carbon emissions and excessive input of labor and machinery all lead to a certain degree of efficiency loss.The improvement of China’s grain production efficiency before 2015 mainly depended on technological progress,technological efficiency,and technological catch-up played a significant role after 2015.In China,the areas with declining grain production efficiency are mostly distributed to the south of Qinling Mountains and Huaihe River,and also in the border areas,and the factors leading to the decline of grain production efficiency are different in different regions.The main grain-producing areas are mainly subject to technological regression;the main grain-selling areas are mainly subject to technical inefficiency,and the areas with balanced production and marketing are mainly subject to the increasing gap between their own technical level and the common frontier.
