Abstract: The intertwined interests among online live-streaming platforms, online celebrity anchors, and live-streaming users have gradually brought live-streaming platforms into the field of criminal law by using technical support and other means to provide assistance for crimes. As an important bridge and pillar connecting consumers and Internet celebrities, the behavior of live-streaming platforms concealing and shielding Internet celebrities from selling fake and shoddy products and providing protective umbrellas for criminals will not only cause huge property losses to the public but also seriously threaten the stability of economic development and market order. Therefore, how to effectively prevent this phenomenon has become a practical problem that needs to be solved urgently.
As the primary subject of risk control and primary object of supervision of compliance operations, the online live-streaming platform is the key to controlling the chaos of online live broadcasting. In view of this, based on the dual identities of live-streaming platform managers and perpetrators, the revenue cost from the perspective of crime economics is first analyzed to obtain the influencing factors of online live-streaming platform crime decision-making in this paper. Secondly, a four-way evolutionary game model of online celebrities, live streaming platforms, consumers, and regulatory authorities are constructed, mainly discussing the influencing factors and evolutionary drivers of criminal and management decisions of online platforms. Finally, countermeasures to prevent online live-streaming crimes are proposed. The innovation of this article lies in the fact that: (1)Considering the dual identities of live-streaming platforms. (2)The four-way evolutionary game model is constructed, and the participants in the system are included in the evolutionary game model. (3)Using the theory of crime economics, the cost and benefit analysis of the cost and benefit of the live broadcast platform with the sticky characteristics of the “Internet celebrity economy” is carried out for the first time.
The findings of this paper are as follows. First, as a perpetrator, the criminal decision-making of online live-streaming platforms is jointly affected by factors such as illegal income generated by illegal rent-seeking, operating costs, negative reputation value, crackdown strength of government functional departments, criminal punishment intensity, investment cost and credibility of crime control. Second, as a manager, the strategic choice of an online live-streaming platform is closely related to the quality control of online celebrities with goods, the degree of consumer rights protection, and the strategic choice of strict government supervision. When online celebrities and online live-streaming platforms reach illegal rent-seeking cooperation, consumers’ active rights protection becomes the best strategy. It can be seen that the different strategy choices of online celebrities and live streaming platforms are not the optimal decisions of the two, and the choice of the same strategy is the optimal decision of the two. Due to the large number and scale of Internet celebrities, it is a good idea to firmly grasp the first line of defense of platform supervision and re-transform the platform from the role of perpetrators to the role of regulatory managers.
Considering the influence of the dual identities of live-streaming platform managers and criminals on the subjects of live-streaming systems, this study reveals the strategic selection mechanism of each game subject through the four-way evolutionary game, which provides theoretical thinking for solving the problem of online live-streaming crime in the era of Internet celebrity economy. However, in the period of great development of live broadcasting, the decision-making process of each subject will be dominated by subjective internal emotions. So, in further research, the influence of subjective preference factors of game subjects on system evolution and results will be considered, and multi-period game comparisons will be carried out.
