摘　　要：通过构建非对称双边网络的竞争模型,分析了垄断、开放和封闭平台的所有权结构和投资策略选择,研究发现:从利润和社会福利的角度来说,非对称网络是最优的,即最优的所有权结构是网络效应强的一方;在竞争的情形下,开放时的总福利高于封闭情形,两个平台兼容为一类消费者接入到另一个平台提供了便利,提高了消费者剩余.不同制度相比较,垄断平台的利润是最高的;开放平台的社会福利是最优的.The paper considers competitive models of asymmetric two-sided networks, analyzes own- ership structure and investment strategy selection under mologoly, open and closed platforms and finds that asymmetric network is the best among three platforms from profits and social welfare point of view and the optimal ownership structure is the strongest side of network effects. While compared open system with closed one in competitive cases, the total welfare is higher in open platform and the compatible platforms provides convenience for the consumers which have access to another platform and increases consumer surplus. Platform competition does not change the platform-supply and price structure in two-sided market. Compared different platforms the profits is the highest under monopoly platform and social welfare is desirable under open platform.
