The Evolutionary Game Analysis And Incentive Mechanism Design For Mobile Application Security Governance

Mobile application security has become an important issue in China's Internet governance.The endless mobile application security issues undermine personal interests of the public directly and restrict the healthy development of the mobile application market.In this regard,the government departments have made efforts to strengthen the construction of administrative supervision system.The public,third parties,and application platforms have also participated in the process,promoted the governance of mobile application security jointly.However,the governance effect is not ideal based on the actual situation,the reasons include the lack of supervision by the government departments,the low level of public participation,the weak third-party binding force,and the lack of management responsibility of application platforms driven by the interest.This thesis starts with a review of the status quo and existing core issues of mobile application security governance,uses evolutionary game theory and principal-agent theory as the main research methods to portray the dynamic evolution of strategies between government agencies,the public,third parties,and application platforms under bounded rationality,and study how the three parties above design a reasonable contract to restrict the application platforms' violations.The introduction of evolutionary game and principal-agent method has opened up a new perspective for the research of mobile application security.The research contents of this thesis are as follows: 1.Introducing the research background and significance,research ideas and methods,and proposes research goals and innovation points based on domestic and foreign research review,the current status and existing core issues of mobile application security governance;2.Using evolutionary game theory to development twoparty evolutionary game systems between government departments,the public,third parties,and application platforms to capture the equilibrium linkage between the various entities,reveal different decision parameters changes and the initial conditions of the game affect the evolutionary stability results,and interpret the physical meaning of the decision parameters combined with the actual situation;3.Using principal-agent theory to study the incentive and supervision issues of government departments on application platforms under incomplete information.Explore the contract incentive effect of two factors of public participation and reputation mechanism.At the same time,use qualitative analysis methods to research how the public and third parties incentive and supervise the application platforms effectively.4.Using MATLAB 7.0 and R language as the simulation tool to verify the consistency between research conclusions and numerical results,so as to display the evolutionary and stable results of the system over time as the value of the decision parameter and the initial conditions of the game is changed systematically,and to present the continuous trend of changes of the key parameters as the value of each factor changes intuitively.To a certain extent,this makes up for the inadequacy of thesis' s ability to collect data for empirical research.5.Combining with research conclusions and numerical results,propose targeted countermeasures from four levels of government departments,social publics,third parties,and application platforms,and build a “four-in-one” mobile application security multivariate co-governance system.Summarizing the research content from theoretical framework and model construction two aspects,points out the research insufficiency and the improvement direction.The research conclusions have a good theoretical and practical significance for promotion of mobile application security governance effectively.
