Using the regression analysis method as a sample, test the path mechanism of “entrepreneurial orientation - dynamic capability - digital transformation”, using the data of companies listed on the GEM in China from 2015 to 2022. Research found that entrepreneurship orientation can significantly promote the digital transformation of enterprises, an effect reinforced by the degree of competition in the industry; institutional analysis shows that entrepreneurship orientation can promote digital transformation by improving the dynamic capabilities of enterprises; heterogeneity tests found that compared to state-owned and non-high-tech enterprises, among non-state-owned and high-tech enterprises, the entrepreneurial orientation has a stronger role to play in facilitating the digital transformation. The results have expanded the cause research and path mechanism at the micro-level of digital transformation of enterprises, which is an important enlightenment to help enterprises achieve digital transformation and build a digital economy system.
