Abstract: For the past few years, the relationship between physicians and patients has become increasingly tense and prominent. To solve this problem, based on the analysis of typical physician-patient incidents in China during the past five years, we take the degree of trust, the degree of information asymmetry, and the cost of diagnosis and treatment into account firstly. Then, we use evolutionary game theory and replicating dynamic equations to construct the evolution model. Finally, this paper explores the evolution path of physician-patient relationship and its influencing factors. The results shows that in the long run, there are two evolutionary paths in the physician-patient relationship game system: positive cooperation and passive cooperation. Increasing the degree of trust between physicians and patients, reducing the degree of information asymmetry between physicians and patients, reducing the cost of cooperation between physicians and patients, and increasing the reward and punishment of government-led arbitration institutions for both physicians and patients will lead to a shift from passive cooperation to active one.

Key words: physician-patient relationship, active cooperation, passive cooperation, trust, information asymmetry
