为探究在后疫情时代旅游市场供需严重倒挂下共享住宿平台企业的定价策略，基于Hotelling模型，通过分析共享平台双边用户不同归属性下的定价决策，对比讨论网络外部性和用户归属性对共享住宿平台企业定价策略的影响。研究发现：在竞争市场环境下，不同共享住宿平台企业向房东（或消费者）制定相同的服务费率对自身最有利；当平台间差异化水平较低时，用户多归属对平台、消费者剩余及社会福利都更有利；归属性会改变平台间差异化水平、组间交叉网络外部性和组内网络外部性对服务费率、利润的影响，但不改变对消费者剩余和社会福利的影响。

In order to investigate the pricing strategies of shared accommodation platform enterprises under the severe imbalance between the supply and demand in the tourism market in the post-pandemic era,based on the Hotelling model, by separately analyzing the pricing strategies under different bilateral user affiliations on the shared platform, this study comparatively discusses the impact of network externalities and user affiliation on the pricing strategies of shared accommodation platform enterprises. The findings reveal that in a competitive market environment, it is most beneficial for different shared accommodation platform enterprises to set the same service fees for landlords (or consumers). When the level of differentiation between platforms is low, multi-homing is more advantageous for platforms, consumer surplus, and social welfare. User affiliation alters the impact of the level of differentiation between platforms, cross-group network externalities, and within-group network externalities on service fees and profits, but does not change its impact on consumer surplus and social welfare.
