技术进步偏向性变动对全要素生产率增长的影响

Does Total Factor Productivity Growth Result from Biased Technical Change?

基于CES生产函数分解全要素生产率增长率,考察技术进步偏向性对要素结构和全要素生产率的作用效应,证明技术进步偏向性变动会通过改变要素结构从而影响全要素生产率增长。数据显示,我国整体经济和东中西部地区技术进步偏向于资本程度逐年减弱;技术进步偏向性变化趋势提高了全要素生产率增长率,且技术进步偏向性与要素结构适配性逐年增强,并呈现出愈加有利于全要素生产率增长的趋势。

This study estimates total factor productivity growth based on the extension of CES production function, and discusses the impact of biased technical change on factor structure and total factor productivity growth, proving that biased technical change will change the factor structure and total factor productivity. It also shows ： a） the level of capital-biased technical change declines year by year; b） this trend of biased technical change has accelerated total factor productivity growth; c） the suitability of biased technical change and factor structure enhance yearly, which is beneficial to improve total factor productivity.
