我国全要素生产率的估算及收敛性检验——基于DEA方法的实证分析

摘要

Based on the non-parametric stochastic frontier production function, this article measures and calculates the change of total factor productivity (TFP)of China and three regions from 2000 to 2014 according to the data of total output, capital input and labor input,and makes the convergence analysis. The results show that TFP of China has a growing trend,but the effect isn't obvious, and the growth of TFP mainly depends on technological progress. The TFP of the eastern region is higher than that of China while the growth rate of TFP of the central and western regions is below the national average. The source of TFP growth of the eastern region is technological progress while the going-down of TFP of the central and western regions is due to pure technical efficiency and scale technical efficiency. There exist both σ convergence and β convergence in TFP of China and three regions.%基于非参数前沿生产函数,根据总产出、资本投入和劳动投入数据,测算2000—2014年全国及三大区域的全要素生产率的变化,并进行收敛性分析.结果表明:我国全要素生产率呈现增长趋势,但效果不明显,且全要素生产率的增长主要由技术进步发挥促进作用.东部地区的全要素生产率高于全国水平,中部和西部的全要素生产率增长率低于全国水平,促进东部地区全要素生产率增长的源泉是技术进步,中部和西部的全要素生产率下降是由纯技术效率和规模技术效率造成的.全国和三大区域的全要素生产率均存在σ 收敛和β 收敛.
