本文通过随机前沿水平模型,对沙特国内的小麦生产、大麦生产以及面粉加工业的全要素生产率及其组成:技术效率、技术进步和规模效率的变化进行分析,结果发现,小麦生产和大麦生产的全要素生产率的变化主要由技术进步的变化多引起;面粉加工业的全要素生产率的变化主要由技术进步和技术效率这两方面的变化引起;规模效率的变化对这三个产业的全要素生产率的变化贡献都很小。 Based on the stochastic frontier model, this paper analyzes the total factor productivity of wheat production, barley production and flour processing industry in Saudi Arabia and its composition: technical efficiency, technological progress and changes in scale efficiency. The results show that wheat production and barley production The change of total factor productivity is mainly caused by the change of technological progress; the change of total factor productivity of flour processing industry is mainly caused by the change of technological progress and technical efficiency; The change of scale efficiency has a negative impact on the total factor productivity of these three industries The contribution of change is very small.
