无差异或完全差异化的双边市场结构在现实经济中并不常见,更为普遍的情形是平台企业经营部分重叠业务.基于Hotelling模型构建了具有部分重叠业务的双寡头双边平台企业竞争模型,围绕两种情形对其均衡解的存在以及均衡解的结构展开了分析.研究发现:分别经营特色产品的双寡头双边平台企业在两种情形下实现均衡时,同侧最终用户的均衡价格、市场份额、获得的利润均相等;存在完全单归属最终用户的情形下,单归属最终用户的均衡价格与重叠业务比例呈负相关,而部分多归属最终用户的均衡价格与重叠业务比例呈正相关;部分多归属与竞争是否激烈的关系并不明确.
Binary market structure with no difference or complete differentiation is uncommon in the real economy, and the more common situation is that the platform enterprises operate partially overlapped business.Based on the Hotelling model, the business competition model of the duopoly oligarchy with partial overlapping business is built around Two cases analyze the existence of the equilibrium solution and the structure of the equilibrium solution.It is found that when the duopoly firms with unique products respectively balance the two scenarios, the equilibrium price of the same-side end-users and market share , And the profits obtained are equal. In the case of completely single end user, the equilibrium price of single home user is negatively correlated with the proportion of overlapping business, while the equilibrium price of some multi-homed end users is positively correlated with the proportion of overlapping business. The relationship between ownership and competition is not clear.
