Research on Public Opinion Dissemination Model and Countermeasures

With the maturity of information technology year by year, the information technology such as communication, network and media is developing unprecedentedly. In order to improve the guidance and control of network public opinion, the research of public opinion control has attracted more and more attention. In this paper, based on the theory of differential equation, the general principles of mechanism analysis and parameter identification are used to establish the model. This paper studies the dissemination law and effect of positive information and negative information under normal conditions. By controlling the model parameters, it reasonably analyzes and puts forward the active strategy of effective control of public opinion information. According to the specific situation of the confrontation conditions, the model is expanded to make it more in line with the actual situation under the confrontation conditions. Finally, through the obtained model, the practical significance of each parameter is analyzed, which proved some theoretical support for the government's decision making in public opinion control.
