摘要
为探析民间舆论场与官方舆论场的交互机理以及其对网络舆情时空传播的影响,并基于理论分析指导信息安全治理实践.根据两个舆论场的交互关系与舆情传播特点,提出了基于双层网络的网络舆情传播模型,重点研究了两个舆论场交互对网络舆情的传播影响.首先求解出了模型的传播阈值R0,并基于R0 分析了舆情传播的平衡点;其次,根据Routh-hurwitz和Lyapunov理论分析了模型在平衡点处的稳定性;最后,对两个舆论场不同互动情景下网络舆情的传播进行了仿真分析.实验表明,模型接近于现实系统并能够较真实地模拟舆情在现实网络空间中的时空传播规律,为两个舆论场的融合发展以及网络舆情引导研究提供了思路.
Abstract
In order to analysis the interaction mechanism between the official public opinion field and the folk public opinion field and its impact on the spatio-temporal transmission of Internet public opinion,and guide the prac-tice of information security governance based on the research conclusions.According to the interaction of the two pub-lic opinion fields and the characteristics of public opinion dissemination,an Internet public opinion dissemination model based on two-layer network is proposed and applied to study the impact of the interaction of two public opinion fields on thedissemination of Internet public opinion.First,the spreading threshold R0 of the model is solved in the pa-per,and then the equilibrium of public opinion propagation is analyzed based on R0.Secondly,the stability of the model at the equilibrium is analyzed according to the theory of Routh-hurwitz and Lyapunov.Finally,the propagation of Internet public opinion under different interactive scenarios of the two public opinion fields is simulated and ana-lyzed.The experimental results shows that the model is consistent with the real system and can more realistically sim-ulate the spatio-temporal spread of public opinion in the real cyberspace,which provides ideas for the integration and development of the two public opinion fields and the research on the guidance of Internet public opinion.
