It has become a key issue faced by enterprises to adapt and adjust the pace of innovation in the process of high-quality development led by digital manufacturing enterprises. Based on the organizational adaptation theory， it constructed the relationship model of “digital transformation， innovation rhythm and innovation performance”， and took environmental dynamism as the moderating variable to conduct an empirical analysis based on the panel data of China’s Shanghai and Shenzhen A-share manufacturing listed companies from 2008 to 2019. The result shows that there is a positive correlation between digital transformation and the incoherent and irregular innovation pace of enterprises. Innovation rhythm has an inverted U-shaped effect on innovation performance. Innovation rhythm plays a partial mediating role between digital transformation and innovation performance. Environmental dynamics weakenes the positive impact of digital transformation on innovation tempo and the inverted U-shaped relationship between innovation rhythm and innovation performance. The research conclusions connect enterprise digital practice， dynamic innovation track and innovation performance， expand the research fields of digital transformation and innovation pace， and provide theoretical guidance for enterprises’ innovation practice in the process of digital transformation.
