Study On Stock Market Rumor Spread Model With Medium

With the development of the information age,people can express their viewpoints on many social medias,and this also provides a more convenient way to spread rumors,making the spread of rumors faster and wider.At the same time,stock investors' access to information and means of exchanging information have also changed significantly.Mostly,investors can make the best of the various ways to spread the information and provide the stock information that they need.However,because of the rapid development of the network,a lot of malicious information spread among investors,and malicious information greatly damaged the stability of the stock market.Therefore,on the basis of SIR model,this paper introduces the media into the process of stock market rumor dissemination,constructs the IHSRW stock market rumor spread model which is more in line with the real life,and calculates the equilibrium point and the basic regeneration number,and analyzes the stability of the equilibrium point.Explore the factors that affect the spread of rumors.The main tasks are as follows:On the basis of communication dynamics,this paper makes a more in-depth analysis of the characteristics of rumors in the process of spreading rumors in the stock market in the current media era.Therefore,this paper introduces the media into the process of spreading rumors in the stock market,and combined with the psychological characteristics of stock investors,reclassifies the investors in the spread of rumors in the stock market,and increases the number of hesitant people.To construct a IHSRW stock market rumor dissemination model which is more in line with real life,which is helpful to better understand the spread mechanism of stock market rumors.And in response to this novel means of communication,the government should take a series of measures against this mode of communication,such as publishing real and effective information through the official media,or penalizing more active rumor communicators.At the same time,strengthen the management of the Internet.In order to evaluate the effect of these measures,a dynamic model with control measures is established.First of all,according to the twomodels,combined with the theoretical knowledge of propagation dynamics,the equilibrium point and the basic regeneration number are obtained,and the stability analysis of the equilibrium point is also given.More importantly,using Matlab for numerical simulation,it is found that the media plays an important role in the spread of rumors in the stock market.
