Abstract: In recent years, the frequent occurrence of network public opinion events in colleges and universities has greatly affected the reputation of colleges and universities, university students’ values, and social harmony and stability. Network media, university students, universities, and government are the main participants in college public opinion information. Their behavioral decisions will directly affect the evolution of university public opinion information. Based on this, we construct an evolutionary game model of university network public opinion evolution under four participants: network media, student group, university authority and government, and explore the influence of the behavioral strategy of the four participants on the development of university network public opinion. At the same time, a numerical example is given to simulate and test the evolutionary game model, and analyze the influence of various parameters on the direction and speed of the evolution of university network public opinion events. The results show that the main factors affecting the equilibrium of the game system are the intensity of government supervision, the willingness of network media’s report, university’s attention and the self-cognition of university students. The impact of university public opinion events can be better controlled by guiding the behavioral strategies of network media, university students, universities and governments.

Key words: evolutionary game, university network public opinion, behavior decision
