Abstract:This paper takes the platform ecosystem composed of the AIoT platform, developers and manufacturers as the research objects, and discusses how to improve the effort levels of parties and the revenue of ecosystem, and develops differential game models of no incentive mode, cost-sharing mode and collaborative mode. Results demonstrate that, both the cost-sharing mode and the collaborative mode can produce incentive effects. In both models, revenues increase over time, and finally tend to a stable value. Parties have the highest effort levels under the collaborative mode. This mode can not only realize individual Pareto optimal, but also system Pareto optimal. However, if the revenue distribution coefficients are not set reasonably, the revenues of parties under collaborative mode will be lower than that under non-cooperative mode.
