To analyze the cooperation behavior from the perspective of doctors and patients in the smart medical information platform,this paper constructs a random evolutionary game model and introduces random interference factors to represent the information uncertainty in the information platform.Afterward,this paper trans-forms the stochastic evolutionary game model of doctors and patients into a cusp catastrophe model through the limit probability density function,proving that the sudden change mechanism is implied in the behavior evolution of doctors and patients.Finally,the simulation method is used to analyze the evolution and sudden change mechanism of the behavior selection of doctors and patients in the diagnostic informa-tion platform and the interactive information platform.This paper finds that:In the smart medical information platform,the behavior selection of doctors and patients may change drastically due to factors such as perceived value and random interference;When the initial cooperation probability between doctors and patients is high if the security and reliability of information platform are poor,doctors and patients tend not to cooperate;When the initial cooperation probability is low if the information platform security and reliability are good,doctors and patients tend to cooperate;When the initial cooperation probability is at a moderate level,the behaviors of doc-tors and patients in the information platform are more susceptible to the additional benefits of non-cooperation,sudden changes of behavior selection are more probable.This paper analyzes the cooperation mechanism between doctors and patients in the smart medical information platform by combining evolutionary game theory and cusp catastrophe theory.It explains the reasons for sudden discontinuous changes in the behavior state of doctors and patients.The conclusion provides enlightenment for the research on doctor-patient cooperative behavior in the information platform and the development of the smart medical platform.
