Research On The Evolution Mechanism Of Public Opinion Of Listed Companies In Stock Information Manipulation

With the stagnation of Web 3.0,the popularity of emerging Internet media has enabled nformation to spread rapidly at an unprecedented rate.The combination of traditional information manipulatioin and new media has made lew infornmation rmanipulations attraci attention.In the new era of rapid Internet development,everyone can freely express their opinions in the network,not only the company's shareholders,board members and securities analysts in institutional investors,but also ordinary small and medium investors,all of which can be on WeChat.Publish or disseminate information about listed companies in online media such as Weibo,stocks,or forums.But some stakeholders will fabricate and disseminate false information based on their own interests to try to manipulate the stock price.Information is circulated in the Internet,causing the convergen ce of information and opinions,and affecting the securities market*listed companies and society.This information has become a rapid spread of public opinion in listed companies on th e Internet.These phenomena indicate that the supervision and governance of information-based manipulation problems by regulatory authorities are not timely enough.The fabrication and dissemination of false listed companies will cause improper gains for stakeholders.Listed companies and regulatory authorities fail to issue timely and effective false claims.The public clarification announcement has caused small and medium-sized investors with asymmetric information to suffer losses due to false grievances.Therefore,only by deeply studying the evolution mechanism of the public opinion of listed companies that are manipulated by inform ation can we manage the stock information manipulation.Firstly,this paper reviews the related literatures on stock information mainipiulatioin,Band summarizes the information manipulation cases announced by the CSRC.It discusses the division,formation motivation and harm of stock information manipulation types.The information flow in the stock flow,information flow and cash flow in manipulation is focused on resea.rch.The dissemination and aggregation of information flow in the Internet can be called public company's public opinion.Therefore,the two-dimensional listed company's public opinion network is constructed through the complex network,and the complex network parameters in the public opinion network of the listed company are used as indicators to construct the logistic regression model.The identification of stock information manipulation is highly accurate:Secondly,based on the grounded theory,this paper draws the influencing factors affecting the evolution of public opinion of listed companies,and divides them into five major dimensionS,information sources,stakeholders,online media,investors and regulatory authorities.According to the influencing factors of the rooted theory,the system dynamics model is used to construct the dynamics model and the total dynamics model of each subsystem,and the system dynamics equation of the public opinion evolution of the listed company is established.The coefficients in the model are analyzed by the analytic hierarchy process determine.Hunan was selected as a research case,and Vensim simulation software was used to simulate the basic variables and adjustment variables respectively,and the evolution trend of the stocks manipulated by information manipulation was obtained.Finally,according to the analysis of the types,causes and hazards of stock information maniprulation,the influencing factors analysis and simulation results ot the information manipulation of the company's public opinion evolution,respectively,the stock information manipulation and the information manipulation of the listed company's public opinion evolution proposed governance countermeasures.
