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

摘要： 针对我国医患关系日趋紧张,医患矛盾逐渐凸显这一问题,在对中国近五年医患事件进行分析的基础上,分别从信任程度、信息不对称程度、诊疗代价等多个视角出发,利用演化博弈理论和复制动态方程,构建了医患双方合作策略选择演化博弈模型,探究了影响医患关系演化的相关因素。研究表明:从长期来看,医患关系博弈系统存在两种演化路径:主动合作和被动合作;增大医患双方的信任程度,减小医患双方的信息不对称程度,降低医患双方合作成本,增大以政府为主导的仲裁机构对医患双方的奖励和惩罚都将会促使医患双方由被动合作转向主动合作。
