Abstract: This paper analyzes the effect of intelligent manufacturing development on the labor income share. Based on the nested CES production function, this paper constructs a theoretical labor income share framework including intelligent manufacturing and traditional production mode, to describe the mechanism of the influence of intelligent manufacturing on the labor income share. Empirical analysis is carried out by constructing intelligent manufacturing index system and Normalized Supplyside System. The study finds that the elasticity of substitution between intelligent manufacturing and traditional production mode determines the effect direction of intelligent manufacturinglabor extended technology progress on labor income share. Through the Normalized Supplyside System, it is found that the elasticity of substitution between intelligent manufacturing and traditional production mode is complementary, and extended technology progress finally inclines to intelligent manufacturing, which will lead to the decline in the labor income share. In addition, the development of intelligent manufacturing improves the average wage rate and labor productivity. The increase in labor productivity produces excess demand for capital and intelligent manufacturing because of the complementary relationship between the factors. As a result, the increase in labor income share is limited. Therefore, this paper points out that the government should perfect the income security mechanism, such as reducing the labor income tax, and improving the welfare of workers by income redistribution, and the training of labor skills should match the intelligence manufacturing, so as to increase the share of labor income.

摘要： 本文分析了智能制造发展对劳动收入份额的影响。基于嵌套的CES生产函数来构建含有智能制造和传统生产方式的劳动收入份额理论框架，刻画智能制造对劳动收入份额的影响机制，通过构造智能制造指标体系和“标准化供给面系统”进行实证分析。研究发现：智能制造与传统生产方式之间的替代弹性决定了智能制造－劳动扩展型技术进步对劳动收入份额的作用方向。根据“标准化供给面系统”发现智能制造与传统生产方式之间的替代弹性为互补关系，使得智能制造－劳动扩展型技术最终偏向于智能制造，从而降低了劳动收入份额。此外，智能制造发展提高了平均工资率和劳动生产率，但要素之间的互补关系使得劳动生产率的提高对资本与智能制造产生超额需求，提高了资本和智能制造所得，限制了劳动收入份额上升。因此，应完善收入保障机制，如降低劳动所得税收，通过收入再分配提高劳动者的福利保障，同时也要加强对劳动技能的培训，使得与智能制造发展水平相匹配，进而增加劳动报酬，提高劳动收入份额。
