政府干预下多种舆情信息交互传播模型与仿真

为识别重大突发事件中多种舆情信息的交互传播规律和更有针对性地制定干预决策,提出了一种交互传播干预模型。该模型融入了多种舆情信息不平等竞争的特点,扩展了现有的单一舆情信息传播干预模型,并可从交互传播整体视角分析干预措施的作用。案例分析与仿真结果表明：该模型可较好地模拟多种舆情信息交互传播的演化趋势;虽然强势舆情信息比弱势舆情信息的潜在危害大,但是干预决策仍需综合关注强势和弱势舆情信息及其间的交互关系。

Model and Simulation of Interactive Dissemination of Multiple Public Opinion Information under Government Intervention

In order to identify the interactive dissemination rules of the multiple public opinion information (POI) in major emergencies and make the intervention decisions more pertinently, an intervention model of interactive dissemination is proposed. The model integrates the characteristics of the unequal competition of multiple POI, expands the existing intervention model of the single POI dissemination, and could analyze the intervention measures from the global perspective of the interactive dissemination. Case analysis and simulation results show that the proposed model could well simulate the evolution of the interactive transmission of the multiple POI. Although the strong POI is more harmful than the weak POI, the intervention decision-making still needs to pay attention to them and their interaction.
