This study utilizes data from China’s listed enterprises between 2012 and 2022 to comprehensively analyze the influence and mechanism of digital transformation on enterprise performance. The findings indicate the following: (1) Digital transformation can effectively promote improving enterprise performance and dual innovation levels. (2) Digital transformation positively impacts enterprise performance primarily through enhanced exploitative innovation, exploratory innovation, dual innovation balance, and complementarity. (3) Managerial power positively moderates the promotion effect of digital transformation on enterprise performance.
