粮食全要素生产率和技术效率研究进展

Research progress of total factor productivity and technical efficiency of grain

摘要: 粮食全要素生产率和技术效率可以从不同层面较清晰地表达生产技术和土地的投入产出效率，使粮食生产效率问题得以定量分析。对粮食全要素生产率和技术效率的定义进行介绍，概述了关于全要素生产率所包含的影响因素对其作用的研究；介绍了测量粮食全要素生产率的3 种主要方法（指数法、DEA 方法和SFA 方法），综述了相关研究进展。

Abstract: Total factor productivity and technical efficiency of grain can clearly express the input-output efficiency of production technology and land from different levels，and make the quantitative analysis of grain production efficiency. This paper introduced the definition of total factor productivity and technical efficiency of grain，summarized the influencing factors of total factor productivity，introduced three main methods（ index method，DEA method and SFA method） for measuring total factor productivity，at last reviewed the related research progress.
