The Study of Charging Mechanism of Knowledge Payment Platform Based on Tripartite Game Model

Abstract

As a new form of sharing economy, knowledge payment market has developed rapidly in recent years. A reasonable and effective charging mechanism can coordinate the interest relationship between knowledge payment platform and users, maximize the interests of all parties, and promote the sustainable and healthy development of knowledge transaction. This paper constructs a tripartite game model with knowledge demanders, knowledge suppliers and knowledge payment platform as the main body, compares the effects of the quality level of knowledge product}, the price of knowledge product, the level of value-added service and the proportion of transaction commission fees on the decision-making of each game subject. First, knowledge demanders will make purchasing decisions when the marginal utility of money is equal to the marginal utility of quality. At this time, the total utility of knowledge demanders is the largest. Second, in order to increase profits, knowledge suppliers will improve the quality level of knowledge products and price high-quality knowledge products with the willingness of knowledge demanders. And knowledge suppliers will purchase value-added services that will maximize their profits. Third, the knowledge payment platform will maximize its own benefits by increasing the influence on the purchasing behavior of knowledge demanders, improving the efficiency of value-added services, and implementing the commission differential charging for knowledge suppliers.
