| 内容提要 | 前沿研究关注要素流动和结构演变对全要素生产率的影响，并未重视诱发要素流动和结构变化的动力及其对生产率可能产生的影响问题。本文首次采用贝叶斯方法和CES函数标准化系统测算技术进步方向及其偏向强度，通过技术进步偏向性视角考察其与要素结构和全要素生产率的耦合效果。结果发现我国技术进步朝偏向于资本方向发展且其偏向强度以年均7%的速度增长，以影响要素边际生产率方式引发要素非对称流动改变要素结构。同时,全要素生产率增长效应分解结果显示，全要素生产率增长存在技术进步偏向性和要素结构的交互效应,技术进步偏向性对全要素生产率的影响并非一定正向且与交互效应方向相反，其综合效应更多反映纯偏向性效果且不同地区呈现分化趋势，表明技术进步方向与要素禀赋相匹配才能有效提升要素结构和全要素生产率。 |
| Abstract | The literature focuses on the impact of factor mobility and structure evolution on the total factor productivity, while it dosen’t pay attention to the effect on productivity and the factor which induces factor mobility and structure evolution. This paper adopts Bayesian method to estimate nonlinear CES production function and measures the biased level of technical change and the cause of factor structure and productivity change under the view of biased technical change. It points out that the technical change of our country is capital-biased, and appears biased to capital at the speed of 7%, to improve marginal productivity of capital and then change the factor structure. Through DEA based on the panal data, we find that the effect of biased technical change is not to be effective and the direction of the whole and pure biased effect on productivity is contrary to the mutual effect, and it will promote total factor productivity only if the direction of technical change is suitable with the endowment of factors. |
