Based on the definition and dimension of digital capability, this paper develops and designs the scale of enterprise digital capability, and expands the source of dynamic digital capability. Based on the dynamic capability theory, this paper uses 259 paired data of middle and senior managers and employees to explore the relationship among transformational leadership behavior, digital capability and enterprise competitive advantage, it also discusses the moderating mechanism of transformational leadership behavior on digital capability under uncertain environment. The results show that: (1) transformational leadership has a significant positive impact on corporate competitive advantage; (2) digital operation and digital innovation play an intermediary role between Transformational Leadership and corporate competitive advantage; (3) the environment uncertainty positively regulates the relationship between transformational leadership and digital operation, and transformational leadership and digital innovation. This study expands the source of dynamic capability from the perspective of digital capability, and effectively guides the management practice of enterprise digital transformation.
