The development of artificial intelligence has had a far-reaching impact on the labor marketHowever,its influence on labor income level and income gap is still in the exploratory stage,and the quantitative evaluation is insufficient,lacking empirical evidence at the industry levelBased on the artificial intelligence technology model of Acemoglu & Restrepo (2018)and introducing the asymmetric change in the industrial AI development,this paper analyzes the impact and mechanism of artificial intelligence on labor income level and skill income gap from intelligence penetration and boundary extension,and does empirical tests through China's industrial panel data from 2003 to 2020The results show that:(1)artificial intelligence has a significant impact on labor income level and skill income gapIn the long run,the development of artificial intelligence can improve the level of labor income and narrow the skill income gap(2)The impact of artificial intelligence on the income level of low skilled labor is significantly greater than that on the income level of high skilled labor(3)Artificial intelligence can increase the labor income level and narrow the skill income gap by improving the employment level of high-skilled and lowskilled labor
