Analysis of Business Model of Co-Creation Digital-Twin City Using Evolutionary Game

Digital twins that predict various phenomena in the real world by collecting a wide variety of data from the real world and simulating them in cyberspace are attracting attention. The City Digital Twin is a digital twin that uses various environmental data of living environments and urban areas to predict the future state and conditions of the society in which people live. The co-creation digital twin is a digital twin that collects data from city dwellers, and the co-creation digital twin is attracting attention as a method to realize an city digital twin that requires a wide variety of data. The platform operator collects data from residents, performs simulations, and provides various prediction results. In the co-creation digital twin, the business model of how to provide incentives to residents for providing data is the key to realizing a sustainable city digital twin. In this paper, we examine possible business models for cocreation digital twin platform. We then use evolutionary game theory, which can analyze the dynamic relationships among stakeholders using differential equations, to examine what kind of business model for co-creation digital twin platform is desirable.
