This paper investigates the mechanisms of tax incentives and R&D investments on employment absorption, constructs a panel data model with a sample of 4,255 Chinese technology-based SMEs, and adopts a random effect model for empirical evidence after various tests. The research results show that tax incentives and R&D investments of technology-based SMEs positively affect their employment absorption. The positive effect not only exists in the current period but also remains valid in the next period. R&D investment, operating profit margin, and remuneration have more significant positive impacts on employment absorption, while we should pay attention to control and reduce overhead costs. Finally, this paper gives corresponding suggestions and countermeasures from three levels: government, enterprises, and society.
