Aiming at the small world network characteristics of the public, a small world network model is constructed for behavior simulation. The simulation results show that under the three modes of random, cluster priority and distance priority, the risk perception of production links have a significant impact on the public food safety behavior choice. In the "low agglomeration" network, when the risk perception is not considered, the impacts of the distance first and agglomeration first on the public food safety behavior is higher than the impact of random mode. In the "high degree of agglomeration" network, considering the risk perception, the distance priority model has a higher impact on the public food safety behavior than the cluster priority model. The results provide a simulation basis for food safety decision-making.
