Under the strategy of innovation-driven development, how to improve total factor productivity (TFP) through innovation is the key to promote high-quality economic development. This paper takes the Chinese coastal listed companies as research objects and studies the effect of research and development (R&D) investment on TFP. Research shows that R&D investment has a significant role in promoting TFP, and there is a U-curve relationship between them. Further research shows that the promotion effect of R&D investment on TFP will vary according to the nature of property rights, the degree of financing constraints, and the level of marketization. These provide empirical evidence for coastal listed companies to effectively promote TFP through R&D investment.
