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.
