分析大数据背景下网络舆情主体交互机制，提取影响网络舆情传播的关键变量，构建微分方程模型研究不同网络舆情主体交互作用问题，通过MATLAB进行数值仿真研究，根据静态仿真和动态仿真结果，得出网络舆情主体交互效果和变动规律，在此基础上提出了大数据背景下政府应对突发事件网络舆情的事前、事后对策。%Governance mechanism of network public opinion under the background of big data is analyzed, and key variables that affect the network public opinion governance are extracted. And a multi-agents model of network public opinion governance is constructed from differential equations, and the numbers are simulated by MATLAB and model characteristics are researched. And then multi-agents network effects of public opinion and the degree of their interac-tion is obtained according to the static and dynamic simulation results. Finally, put forward are the countermeasures for government-led and multi-agents collaborative governance mechanism to provide a theoretical model for network pub-lic opinion governance and suggestions for public opinion governance effect assessments.
