[目的]在耕地面积有限、城镇化高速发展的背景下,合理评价粮食生产效率,认清粮食生产现状,探索提高粮食生产效率的有效途径.[方法]基于数据包络法(DEA)分别测算了2006-2015年中国31个省(市、自治区)的粮食生产效率,同时借助探索性空间数据分析(ESDA)对其时空格局演变特征进行解析,并通过空间计量模型揭示其驱动机理.[结果]中国粮食生产效率整体偏低,东部沿海地区和西部地区粮食生产效率出现大面积、大幅度下降趋势;粮食生产效率空间集聚效应显著且具有跃迁性,但主要以类型Ⅳ为主,其空间结构具有一定的路径依赖特征;经济增长与粮食生产效率存在正N形的Kuznets曲线,目前大部分地区经济增长的产粮效...

[Objective] To evaluate the efficiency of grain production, recognize the status of grain production and explore an effective way to improve the efficiency of grain production in the background of limited cultivated land area and rapid urbanization. [Methods] The grain production efficiencies of 31 provinces (municipalities and autonomous regions) in China from 2006 to 2015 were measured by data envelopment method (DEA), and the spatial and temporal pattern evolution characteristics were analyzed with the help of exploratory spatial data analys...
