Abstract: With the rapid development of information technology, the sharing of idle capacity has graduallybecome an important capacity utilization mode in the production field. In order to study the optimal pricing of platform when idle capacity is shared, under the condition that the platform collects transaction fees from suppliers and does not charge the demanders, the basic models of commercial platform and public welfare platform are established and compared. The pricing model of platform X with certain weight considering the benefits of other participants is built on the basis of the basic model to discuss the influence of weight on the optimal transaction cost, the quantity of both the supplier and the supplier and the optimal profit of the platform. Finally, the important theorems and the influence of weight on the utility of both parties are verified by the numerical example. The results show that: (1)the optimal transaction fee and the optimal profit obtained by commercial platform are higher than that of public welfare platform; (2)the optimal transaction fee and optimal profit obtained by the platform X considering the benefits of other participants, the quantity and utility of demander increase with the increase of weight, while the quantity and utility of the supplier decrease with the weight. This paper provides theoretical reference for the behavior decision of platform operators and enterprises.
