【摘要】 本文使用我国1992、1995年和1999年三年的县(市)级数据,采用超越对数随机前沿面生产函数,研究了我国粮食生产技术效率的空间分布和影响因素。发现:(1)技术效率在地理空间上的分布是不均衡的,呈现出南高北低的格局:(2)从92年到99年,全国平均技术效率大约下降1%,且效率分布的变异性似乎有加大的趋势;(3)农业生产的自然条件和一些社会经济因素对粮食生产的技术效率有着显著的影响。更多还原

【Abstract】 This paper estimates a translog stochastic frontier production function in the analysis of more than two thousand counties in three years 1992,1995and 1999,to attempt to study the geographical distribution and the determinants of technical efficiency of China~,s grain production .Results indicated that (1)individual technical efficiency estimates exhibit considerable variation among counties;(2)from1992 to 1999,average level of technical efficiency declined about 1%;(3) technical efficiency is significantly influenced by nature conditions of grain production and some Socioeconomic conditions.更多还原
