Abstract: In the context of innovation-driven development strategy, it is of great significance to clarify the characteristics of heterogeneous R&D investment and its different effects on regional economic growth. This paper uses the comprehensive perpetual inventory method to calculate the provincial heterogeneous R&D capital stock from 1998 to 2020, and empirically analyzes the conditions, spatial effects and mechanisms of scientific research and technology development affecting regional economic growth. The results show that:(1) scientific research and technological development have the characteristics of "step-up" threshold effect in the process of promoting regional economic growth, and the threshold condition is related to the regional digestion and absorption capacity; (2) technology development has a significant positive spatial spillover effect, but the spatial spillover effect of scientific research is not significant; and (3) both scientific research and technological development can promote regional economic growth through the effect of human capital and efficiency improvement. Compared with technological development, scientific research makes it more difficult to promote economic growth through the effect of consumer demand. From the perspective of heterogeneous R&D investment, this paper provides policy recommendation for promoting the coordinated development of regional innovation, improving the contribution rate of scientific and technological progress, and implementing the innovation-driven development strategy.
