The healthcare industry is in urgent need of transformation to enhance service efficiency and optimize patient experience. However, theoretical research on how to effectively implement the digital transformation of healthcare remains relatively limited. This paper analyzes the development of digital medical industry from three aspects: opportunity, requirement and direction by means of the theory and method of evolutionary game. Specifically, this paper constructs an evolutionary game model of interests among three main parties: the government, hospitals, and patients, and further conducts simulation analysis through numerical simulation. The research results show that the actions of the digital medical industry depend on whether any of the three parties takes proactive actions. If any party acts proactively, it will drive the system toward a stable point of （1，1，1）; otherwise,  if all parties adopt conservative strategies, the system may remain at the stable point of （0，0，0）. Further analysis indicates that major health events are important opportunities for the medical industry to develop and transform digitalIy. The goverment, hospitals, and patients need to timely update their medical concepts and behavioral inertia, and then accelerate the development of a patient-centered digital healthcare ecosystem across the domains of medical services, pharmaceuticals, and healthcare insurance, ultimately boosting awareness and adoption of digital healthcare services. In addition, the quality of digital medical services is an essential foundation for the transformation of the digital medical industry, and the collaborative development between official hospital platforms and third-party medical platforms is a crucial opportunity for the transformation of the digital medical industry. The collaborative integration between hospitals' official platforms and third-party digital healthcare platforms represents a key opportunity in this transition.
