The Dynamic Mechanism And Evolution Law Of Two Kinds Of Public Opinion Information Transmission Considering Competitive Position

In recent years,China has entered a period of social transformation,and the occurrence of emergencies has shown an increasingly frequent trend.Not only does the emergency itself have a major impact on the production and life of the people,but the bad habits caused by the emergencies are more likely to increase the difficulty of emergency handling of the original incidents and further trigger the overreaction of the people.Emotional publicity is usually accompanied by a variety of public opinion information dissemination,and public opinion cases with two kinds of public opinion information with competitive status have been common.For example,after the Malaysia Airlines loss incident,two kinds of "MH370 are likely to be hijacked" and " Terrorist bombing ";the Gansu Minnan incident triggered two kinds of public opinion information: "The municipal administrative center will move to Cheng County" and "the relocation of the administrative center are purely rumors".The two kinds of public opinion information involved in different public opinion communication cases have different competitive positions.Therefore,this paper mainly takes two kinds of public opinion information with competitive status as the research object,and discusses the dynamic mechanism and evolution law of its evolution,which has important practical significance.Firstly,based on summarizing the research on two kinds of public opinion information dissemination at home and abroad,this thesis expounds the related theories and methods involved in this paper,including the concept of public opinion,system dynamics,and infectious disease models.Then based on multiple case studies,the competitive position of two kinds of public opinion information is summarized,including equal competitive status and unequal competitive position.Secondly,based on the system dynamics theory,two kinds of public opinion information evolution models of equal competitive status and unequal competitive position are established respectively,and the evolution results of two kinds of public opinion information of different competitive positions are analyzed.Through model analysis,it is found that the trend of increase and decrease of two kinds of public opinion information is more consistent under the equal competitive position;in the competition of two kinds of public opinion information(strong lyric information and weak public opinion information)under unequal competitive position,strong public opinion information always dominates.And the propagation period is longer,while the weak public opinion information transmission cycle is short and quickly subsides.Thirdly,based on the dynamic mechanism of two kinds of public opinion information with competitive status,based on the infectious disease model,the evolution model of two kinds of public opinion information under equal competitive position is established,and the time and network of two kinds of public opinion information are analyzed.The average degree,the interaction of two kinds of public opinion information,and the influence of two kinds of public opinion information evolution results;further establish the evolution model of two kinds of public opinion information(strong public opinion information and weak public opinion information)of unequal competitive position,and then set through numerical scenario simulation The influence of the three intervention strategies on the evolutionary results,and thus the best intervention strategy for the interactive communication process of the two lyric information in the unequal competitive position.
