As a new product formed by the traditional business model through the digital technology empowerment mode, the digital business model has a great impact on the digital transformation of micro enterprises and even the quality of macroeconomic development. However, there is still a lack of due attention on the strategic motivation of enterprise digital business model innovation. Based on the senior echelon theory and the institutional theory, the thesis discusses the relationship between the heterogeneity of the executive team and the digital business model innovation, and tests the moderating effect of the institutional environment and the political association on the two relationship.The thesis found that as the level of enterprise digital business model innovation increases, the higher the institutional environment will enhance the positive relationship between executive team heterogeneity and enterprise digital business model innovation, while the political association will weaken the above relationship. Further, for enterprises in non－state－owned enterprises and mature industries, the heterogeneity of senior management team has a more impact on enterprise digital business model innovation is obvious. This thesis analyzes the decision－making motivation of enterprise digital business model innovation from the perspective of senior executive team heterogeneity, and provides relevant enlightenment to better drive the digital transformation of enterprises.
