利用2000－2008年期间26个省区的面板数据，运用超越对数随机前沿分析方法（ SFA）研究了中国农村劳动力结构变化对粮食生产技术效率的影响，并测算了技术效率对全要素生产率（ TFP）以及TFP对粮食增长的贡献。结果表明：在2000－2008年期间，中国粮食生产存在着技术非效率性，农村劳动力老龄化、女性化和教育水平的提高改善了粮食生产的技术效率，但女性化的贡献在逐渐下降；TFP年均增长0.43％，其主要源自于技术效率的提高；TFP对粮食增长率的贡献约为3成，表明中国粮食增长主要是依靠投入拉动的。

This article analyzes the effects of structure change of rural labor force on technical efficiency of grain production by employing the translog stochastic frontier analysis （ SFA） model with panel data of 26 provinces during 2000-2008 in China .The contribution of technical efficiency to the total factor pro-ductivity （ TFP） and that of TFP to grain production growth are calculated .The results show that there is inefficiency in the China ’ s grain production , the aging , feminization and education of rural labor force are beneficial to improve the technical efficiencyof grain production .The average growth rate of TFP is only 0.43%, which is mainly driven by technical efficiency .Input growth is the primary contributor to grain output growth , the TFP contribution is about 30%in the sample period .
