Purpose: The new round of medical reform is a significant exploration of reform in the public service sector in China. Health insurance regulatory departments, medical institutions, and patients, as critical stakeholders in China’s medical reform, play a crucial role in the success of the reform through their strategic interactions. Patients and Methods: Starting from the perspective of bounded rationality, applies evolutionary game theory to establish an evolutionary game model for the collaborative governance of health insurance regulatory departments, medical institutions, and patients and analyzes the stability of each party’s strategy and the sensitivity of parameters in the tripartite game system. Results: The study shows that an equilibrium point will be formed when medical institutions provide reasonable treatment, patients choose to accept treatment, and health insurance regulatory departments adopt a lenient regulatory strategy, maximizing the interests of all parties involved in the game. Factors such as the benefits of unreasonable treatment by medical institutions, fines, and regulatory costs impact the decision-making of health insurance regulatory departments. To maximize social welfare, health insurance regulatory departments should reform payment methods, adjust medical service behaviors of medical institutions, and guide the rational allocation of medical resources; the government should increase subsidies for the operation of medical institutions and the intensity of penalties; regulatory departments should reduce regulatory costs and introduce third-party forces to strengthen health insurance supervision further. Conclusion: The research findings of this paper will provide valuable insights into some countries’ medical and health reform.
