Labor activities can be described on two dimensions, physical energy-based or intelligence-based, regular or irregular. Thus labor activities can be divided into four categories:regularly physical energy labor, regularly intelligent labor, irregularly intelligent labor, and irregularly physical energy labor. That the artificial intelligence replaces the manpower pushes laborers to iterate forwardly and/or upwardly from the original labor field to another. At the same time, the artificial intelligence replaces, strengthens, adjusts and restructures human labor which triggers a continual shock on the labor market in both employment and work welfare. The artificial intelligence expands the connotation of human capital in tradition, but also non-cognitive human capital focusing on abilities to cope with the disequilibria such as technological change, production innovation and enterprise institutional reforms. Faced with the impact from the artificial intelligence, the prerequisite of successful employment iteration is to match human capital investment with strategy.
