摘　　要：针对食品安全行为中公众群体具有的小世界网络特性,构建了小世界网络模型进行行为仿真。结果表明:在随机、集聚优先和距离优先三种模式下,生产环节风险感知对公众食品安全行为选择影响显著。在“低集聚度”网络中,不考虑风险感知时,距离优先和集聚优先模式下对公众食品安全行为的影响高于随机模式。在“高集聚度”网络中,考虑风险感知时,距离优先模式对公众食品安全行为的影响则高于集聚优先模式。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.
