The Evolution Of Social Network User's Information Provision Willingness And The Enhancement Strategy

Users' information leakage events frequently reduce the willingness of network users to provide information,seriously hinder the healthy development of social networks,and bring challenges to the further development of social network service providers.Based on the original theory,this paper adjusts and reconstructs the users'information willingness model,and achieves the changing mechanism of users'willingness to provide information through simulation,which provides a theoretical basis for the strate gic choice of enterprise.At the same time,it is better to make predictions based on changes in user preferences.It is of practical significance to develop personalized marketing for enterprise.This paper firstly sorts out the related theories of user information willingness,summarizes the concept and characteristics of social network,and the DEMATEL method is used to identify the key factors for the willingness of users to provide information in the social network.The usefulness of the website,users trust tendencies,website reputation,flow experience and the sensitivity of the information are crucial to the willingness of users to provide information.That is the reference to further construct the evolutionary game model.Secondly,the model of evolutionary game is constructed,the model of supervising intensity is added,at the same time,the punishment ratio of regulators is added to enrich the model,the evolution stability of the model is analyzed,and the simulation is carried out by using ode 45 commands.Finally,the simulation results and the stability analysis results are consistent,meaning evolutionary game model is reasonable;In addition,this article also studies the evolution of each user's information willingness under the condition of variable expected return,and draws the evolution trend through the use of MATLAB software and carries on the correlation analysis.Through the research found that the supervisory strength coefficient,the information leakage loss and the information sensitivity have a significant impact on users and websites,and the loss of information and the sensitivity of information can affect the direction of evolution of users' information willingness to provide,and only change the speed of website evolution,while the supervisory intensity coefficient is the opposite.Finally,based on the above conclusions,we propose relevant strategies and suggestions on the website's willingness to promote user information.
