Abstract: 【Purpose/significance】Exploring the influence of user information behavior on rumor spreading can provide new ideas for
rumor dispelling work. However, most of the existing studies are based on infectious disease model to study the influence of user infor⁃
mation behavior, while the user information behavior based on game model is incomplete.【Method/process】In order to remedy this
shortcoming, on the basis of the original user information behavior model, the user questioning behavior is introduced, and the user in⁃
formation behavior game model considering the questioning effect is constructed. The constraints of the best state of the rumor rejec⁃
tion effect are analyzed and the parameters in the model are simulated.【Result/conclusion】The results show that users' questioning
behavior can improve the dissemination effect of rumor information, but excessive questioning will have a negative effect on rumor con⁃
trol. Finally, according to the simulation results, some suggestions are given to improve the dissemination effect of anti-rumor informa⁃
tion.【Innovation/limitation】The user information behavior game model proposed in this article is closer to social reality. In future re⁃
search, introducing real data to verify the model will be considered.
