RESUMEN
The paper analyzed the decision-making process of the doctor's treatment and patient's decision-making. Then established the evolutionary game model of patient's and the secondary-tertiary hospital doctor's strate-gy. The Matlab simulation software were used to analyze the influencing factors of patient-doctor strategy-making sys-tem. We proposed the advice reducing critical patient's utility loss diagnosed in secondary hospital,improving medi-cal experience of common patient in secondary hospital,strengthening disease prevention of critical patient,and pro-moting labor division and cooperation between secondary and tertiary hospital to make result develop towards reduction the disorderly,chaotic and dislocated medical need and an integrated secondary and tertiary system.
