Cooperation Strategies between Internet Celebrities and Brands from the Perspective of Differential Games
摘要
Abstract
In the context of the digital economy,the rapid development of the live-streaming industry has signifi-cantly promoted social and economic progress.By 2023,the number of short video users in China had reached 1.012 billion,and the number of live-streaming users had stood at 751 million,making the live-streaming industry the leader in China's social media sector.This surge in internet celebrity-driven live commerce has posed a considerable challenge to traditional direct-to-consumer e-commerce.Consequently,brand manufacturers face a crucial dilemma:how to leverage internet celebrity live-streaming channels to maximize profits,consider-ing the impact of internet celebrities and the chosen mode of cooperation? To explore the optimal cooperation model between internet celebrities and brand manufacturers on live-streaming platforms,while accounting for the continuous nature of live-stream traffic and time,this paper constructs a differential game system involving one internet celebrity and brand manufacturers selling similar products.By employing the Hamilton-Jacobi-Bellman equation,we analyze the optimal decisions regarding effort levels and corresponding payoffs for both internet celebrities and brand manufacturers under three cooperation models:the decentralized decision model,the centralized decision model and the fairness concern model.Through theoretical analysis of the effort levels and overall system revenue under these three cooperation models,coupled with the numerical experiment using real data from the live e-commerce analytics platform"Douchacha,"we derive the following conclusions. (1)In the centralized decision model,both the effort levels of the internet celebrity and the brand manufac-turer,as well as the level of live-streaming traffic,are maximized.This model facilitates the highest degree of cooperation and synergy between the parties,thereby significantly enhancing market promotion effectiveness and overall revenue. (2)In the decentralized decision model,each party makes independent decisions without global cooperation and coordination,which limits the efforts of both the internet celebrities and the brand manufacturers.Conse-quently,the system's overall performance is the lowest in this model due to the lack of a cohesive strategy and mutual alignment. (3)In the fairness concern model,the system achieves the highest overall profit.By appropriately reducing the fairness concern of the internet celebrity towards each brand manufacturer or increasing the commission paid by the brand manufacturers to the internet celebrity,both the internet celebrity's and the brand manufacturers' profits can be effectively increased.Such coordination can ensure the maximization of the interests of all parties involved,thereby achieving a true win-win situation. Through a comparative analysis of theoretical and numerical experiments,it is evident that the centralized decision model and the fairness concern model facilitate deeper collaboration between internet celebrities and brand manufacturers more effectively than the decentralized decision model.This approach not only yields higher returns for both parties but also supports the healthy and efficient development of the internet celebrity economy,fostering long-term growth in the industry.关键词
