Abstract:Abstract: Based on the data of China’s A-share listed companies from 2011 to 2020 as the research sample, and studies the impact of trade credit financing on the total factor productivity of enterprises from the perspective of life cycle. The empirical results show that the relationship between trade credit financing and the total factor productivity of enterprises shows an inverted U-shaped trend, there is an impact of “incentive” and then “crowding out”; from the perspective of enterprise life cycle, the incentive impact of trade credit financing on the total factor productivity only in the mature stage companies, and the inverted U-shaped impact is concentrated in the growth stage and recession stage companies. Further research finds that differences in ownership and scale of enterprises in different life cycles will lead to significant differences in the relationship between trade credit financing and total factor productivity.The research conclusions of this paper enrich the literature on trade credit financing and enterprise total factor productivity, and have certain practical significance for enterprises in different life cycles to reasonably determine the scale of financing and improve production efficiency.
