摘　　要：[目的/意义]不同突发事件或不同网络平台上的舆情信息扩散存在差异,本文构建数理模型研究舆情信息的不同传播扩散机制,度量舆情信息扩散差异,为突发事件网络舆情精准治理提供理论支持。[方法/过程]本文针对舆情信息扩散一般特征,考虑各突发事件和各网络平台的不同对舆情信息扩散的影响,提出舆情信息扩散指数的概念,构建一种基于幂映射的突发事件网络舆情信息扩散差异性度量模型,并通过数值仿真研究参数对舆情信息扩散的影响。通过使用多起突发事件引发的网络舆情案例数据来验证模型的有效性及合理性,同时利用多个案例验证本文模型对信息扩散预测的有效性。[结果/结论]突发事件网络舆情信息扩散的差异性可用舆情信息扩散指数度量。舆情信息扩散整体规律一致,舆情信息扩散指数对舆情信息扩散的影响不仅体现在时间维度,还体现在舆情信息量维度。[Purpose/Significance]There are differences in the diffusion of public opinion information between different emergencies and network platforms.This paper constructs a mathematical model to study the dissemination and diffusion mechanism of public opinion information,measures the differences in public opinion information diffusion,and provides theoretical support for precise governance of emergency network public opinion.[Method/Process]This paper focused on the general characteristics of public opinion information diffusion,considered the impact of different emergencies and network platforms on public opinion information diffusion,proposed the concept of public opinion information diffusion index,constructed a power-mapping based on measurement model for the difference in public opinion information diffusion on the network of emergencies,and studied the influence of parameters on public opinion information diffusion through numerical simulation.The validity and rationality of the model were verified by using the network public opinion cases data triggered by emergencies,and the effectiveness of the model for information diffusion prediction was verified by using multiple other cases.[Result/Conclusion]The difference of network public opinion information diffusion in emergencies could be measured by the public opinion information diffusion index.The overall law of public opinion information diffusion is consistent.The influence of public opinion information diffusion index on public opinion information diffusion is not only reflected in the time dimension,but also reflected in the public opinion information volume dimension.
