Due to the imperfect financial system in China，trade credit financing plays a vital role in the development of enterprises.Based on the data of A‐share listed companies in Shanghai and Shenzhen from 2011 to 2020，an empirical study was conducted between enterprise digital transformation，trade credit financing and the influencing mechanism. It is found that digital transformation of enterprises has significantly improved trade credit financing. The channel test shows that digital transformation attracts trade credit financing by reducing supplier concentration，improving enterprise market position and increasing information transparency. In addition，digital transformation has a more significant effect on enhancing trade credit financing for state‐owned enterprises，non‐high‐tech enterprises，and enterprises located in regions with lower levels of institutional environment. The results explore the specific performance of digital transformation to ease financing constraints and enrich the research on the outcome factors of digital transformation.
