According to more and more frequent violence in football match places, prediction and analysis are conducted on football fans violence from group behavior perspective in order to guide the fans to be more rational. By the questionnaires from 158 football fans on referees, visiting team and fans, regression analysis is conducted on prediction factors of the fans violence behaviors under four situations. The results show that under four situations, four factors such as collective identity identification and so on have significant prediction effect on the fans violence behaviors, especially for soft violence behavior prediction. When multiple factors put together, the frequency for serious violence behaviors begins to increase, which embodies the dynamic feature of group violence behaviors of the fans.
