摘　　要：本文运用DEA模型和ESDA方法对2008-2012年山西省107个县（市）农业生产效率及其时空变化特征进行了深入的探究,结果表明：①2008-2012年山西省农业生产综合效率、纯技术效率以及规模效率处于中等水平,并且保持了一定的增长态势,但是全省农业生产效率的区域差异较大;从综合效率的区域特征上看,高效率区主要位于山西省中部及东南部,低效率区主要位于山西省西部;将综合效率进行分解,可以看出纯技术效率对综合效率的贡献大于规模效率;并且大多数县（市）处于规模收益递增阶段;②2008-2012年全省县（市）农业生产效率表现出显著的空间相关性,但是空间集聚性逐年下降,空间差异扩大;③从局部空间特征上看,山西省东南部部分县（市）农业生产效率下降,西部少数县（市）农业生产效率有所提高,同时,晋北、晋南地区一些县（市）农业生产效率也有所降低.Using the methods of Data Envelopment Analysis（ DEA） and Exploratory Spatial Data Analysis（ ESDA）,this paper conduct in-depth analysis on the agriculture production efficiency of 107 counties in Shanxi province and its evolvement from the year of 2008 to 2012. Some conclusions are drawn as follows： ① The comprehensive efficiency of agriculture production of Shanxi is at an intermediate level during the study period,and keeps a moderate rate of growth. The gap among regions is quite huge,areas of high comprehensive efficiency locate mostly in the middle and southeast of Shanxi province,while areas of the relatively low comprehensive efficiency in the west. And PTE（ pure technical efficiency） contributes more to the TE（ total efficiency） compared with SE（ scale efficiency） after the TE is classified,and most counties are at the stage of growth in SE. ② The agriculture production efficiency in Shanxi province show obvious spatial auto-correlation,while the spatial clustering of similar-efficiency areas tends to decline and the gap widens. ③ From the local perspective,the agriculture production efficiency in some counties in the southeast of Shanxi declines together with some in the south and north,while a few in the west increases.
