Abstract:    Collaborative innovation is a key link in the deployments of "the system and mechanism of technological innovation" in China. The technology personnel mobility and government R&D subsidies have important impacts on collaborative innovation. However, there is little research on the combined effects of the two factors. This paper used a system GMM model to estimate the combined effects of the two factors and examined the threshold effect of government R&D subsidies and the moderating effect of marketization level. The research found that: (1) the knowledge spillover effect generated by the technology personnel mobility has a significant positive impact on industry-academia and government-industry collaborative innovation; (2) By stimulating the enthusiasm and reducing R&D costs, government R&D subsidies have promoted industry-academia, government-academia, and government-industry-academia collaborative innovation; (3) The degree of marketization has a positive effect on university-industry collaborative innovation, however, the degree of marketization negatively moderates the positive effects of scientific and technological personnel mobility and government R&D subsidies on university-industry collaborative innovation; and (4) when government R&D subsidies are at an appropriate level, the technology personnel mobility can better improve the level of various types of collaborative innovation. This study has provided a theoretical basis for the government to make reasonable use of R&D subsidies and better leverage the role of technology personnel mobility in promoting collaborative innovation between government, industry and academia.

Key words: technology personnel mobility, government R&D subsidy, collaborative innovation, marketization level
