摘　　要：双边市场是指平台两边有两组不同的代理人,通过一个公共平台发生交易,双边市场的重要特征是平台两边不同用户之间存在着间接网络外部性,用微分博弈的最优控制方法研究双边平台网络中在位者平台和高质量进入者的动态竞争,发现驱动市场成功的长期市场结构和市场效率的关键依赖于平台的质量和间接网络效应。均衡时两个平台或者共存或者占优,依赖于平台策略的选择。Two- sided market is the one in which two groups of agents interact with each other via a common network platform and the value of participating in the network for agents in one group depends on the number of participants from the other group. Such market is mainly characterized by the cross - group network effects. With the optimal control approaches to the dynamic competition in two- sided networks between incumbent and entrant with a quality advantage, the paper finds out that the driver of platform success, long - run market and market efficiency depend critically on two parameters . the strength of indirect network and the quality advantage of its platform.
