Abstract: On the basis of systematically analyzing the linear and nonlinear effects of R&D outsourcing on total factor productivity, this paper empirically examines the effects of R&D outsourcing on total factor productivity from two aspects of "incentive-nonlinear incentive". The results show that R&D outsourcing significantly promotes total factor productivity; Due to the impact of independent R&D investment intensity, government support and human capital level, there is nonlinear threshold characteristics. With the increase of R&D investment intensity and human capital level, R&D outsourcing plays a stronger role in promoting total factor productivity. As the level of government support increases, the promotion effect weakens. The heterogeneity test for different ownership, industry type and regional classification shows that R&D outsourcing has a significantly stronger effect on total factor productivity in non-state-owned enterprises, companies with high capital intensity and enterprises in east and central China. Affected by relevant threshold factors, there are significant differences in threshold characteristics among enterprises of different categories.
