摘要:
为识别公众风险感知的演化规律和官方媒体参与的作用机制,首先,根据公众的行为表现划分不同风险感知群体,并分析群体间的相互竞争和官方媒体的扰动作用;然后,通过扩展LotkaVolterra模型建立群体间的相互竞争模型;在此基础上,通过推导模型平衡点及其稳定性分析模型演化规律;最后,运用数值仿真考查了官方媒体的参与对模型演化的影响。研究结果表明:模型演化具有3种结果情景,官方媒体参与能够显著改变模型演化的速度和结果。
Abstract:
It is of great significance to identify the evolution law of public risk perception and the mechanism of participation of official media in order to maintain the response order and implementation of plans. Firstly, groups with different risk perception are divided according to public behavior, and the competition between different groups and the disturbance of official media are analyzed. Then, a mutual competition model is established through extending the LotkaVolterra model between groups. Further, the model equilibrium point and its stability of are derived to analyze the evolution law of this model. Finally, numerical simulation is conducted to examine the effect of the participation of official media on the evolution of the proposed model evolution. The results show that there are three scenarios of evolution results of the model, and the participation of official media can significantly change evolution speed and result of the model.
