Outline
New quality productivity relies on technological innovation to achieve efficient production through strategic emerging industries, and research and development investment is the key to its formation. By constructing a computable general equilibrium model to explore the inherent logic of the impact of R&D investment on the development of new quality productivity at the theoretical level, data from listed companies from 2000 to 2019 was used for empirical analysis. The results show that R&D investment significantly improves the overall factor productivity of high-tech industries. The degree of economic marketization plays a regulatory role in this process, with the central region being most significantly affected, followed by the eastern region, and the western region having the least impact. In addition, the government market relationship in the eastern region plays an important role in regulating the impact of high-tech enterprise R&D investment on total factor productivity. The study reveals the differential impact of R&D investment on total factor productivity in different regions, and suggests continuously increasing R&D capital for strategic emerging industries and implementing differentiated policies according to local conditions to promote economic development.
