突发公共卫生事件中伪健康信息传播的系统动力学模型研究

Study on the System Dynamics Model of Pseudo-health Information Dissemination in Public Health Emergencies

基于SIRS模型构建突发公共卫生事件中伪健康信息传播的系统动力学模型,分析伪健康信息在网络空间的传播过程、影响因素,结果表明易感人群数量、突发公共卫生事件等级、健康信息素养、关系强度、政府公信力等影响因素对突发公共卫生事件中伪健康信息传播起到关键作用,进而提出相应治理建议。

A system dynamics model for the dissemination of pseudo-health information in public health emergencies is built based on the SIRS model,and the dissemination process and influencing factors of pseudo-health information in network space is analyzed.The results show that the number of susceptible population,the level of public health emergencies,health information literacy,relationship strength,government credibility and other influencing factors play key roles in the dissemination of pseudo-health information in public health emergencies,and then the corresponding suggestions on governance are put forward.
