Under the wave of digitalization, traditional enterprises adopt digital technology to achieve innovation, transformation and even upgrading. However, extant research lacks a theoretical explanation for how digitization affects the formation of innovation ecosystems. Therefore, based on the empowerment theory, the development history of the state-owned real estate company—Chengdu XingChengRenJu Real Estate Investment Group Co., Ltd. was explored to figure out how digitalization empowers the formation of firms’ innovation ecosystem. The research results show that through resource empowerment, psychological empowerment and structural empowerment, digital technology empowers actors in the ecosystem, such as core enterprises, employees, and customers, and continuously to realize the internal information management of innovation entities and the interaction between innovation entities. The sharing and collaboration of enterprises enables enterprises to realize a leap-forward development from a single firm, to firms with various collaborators, and finally forming an innovation ecosystem. The research conclusions are helpful to provide theoretical guidance and practical suggestions for the digital construction and ecological development of traditional enterprises.
