Total Factor Productivity Growth Decomposition of Agricultural Production in West Regions——Based on Panel Data of 2000～2007

This paper analyses the total factor productivity growth decomposition of agricultural production in west regions of 2000-2007 with stochastic frontier production function approach,and splits total factor productivity changes into 4 components:technical process,technical efficiency change,scale efficiency,allocative efficiency.The result shows:increasing rate of total factor productivity growth is 5.74% on average in 2000～2007 of west agricultural production,The main influencing factors are technical progress,allocative efficiency and scale efficiency.The technical progress is the key motive force,which accounts for 104%;scale efficiency 8%;the change of technical efficiency decreases slowly,which accounts for 0.87%.The influence of resource distribution is reverse,which accounts for 11.27%.In order to improve the agricultural production technology efficiency level in the west,we need to popularize new variety and new technology,and adjust resource allocative structure.
