Abstract To achieve an effective response to negative emotions in public risk events, this study analyzes the interrelationship among individual attributes, risk perception and emotions, It establishes an emotion evolution model based on social comparison theory, considering the impact of governmental responses, and examines the mechanisms underlying the generation of different emotions and their intercorrelation in public risk events, and further carries out simulations under different scenarios. Results show that the openness of online social networks promotes the evolution of emotions and at the same time reduces regional differences. When the government responds, the anger individuals feel can be reduced with an increased overall risk response level, but this can also lead to an increase in their fear. When there is a strong correlation between individuals’ risk perception and their locations, risk communication is more effective at guiding negative public emotions than making simple adjustments to the official response.
