To deal with safety risks in a peer-to-peer (P2P) trading economy platform, later customers may consider the decision of prior customers, constituting an environment where herding behavior may occur. This study intends to investigate herding behavior in such platforms and explore the boundary conditions. The study identifies the following findings: (1) The number of prior bookings for accommodation is positively associated with the number of future bookings. (2) As more prior customers use self-defined rather than default names or photos, the positive effect of the number of prior bookings is strengthened. (3) For a host with a self-defined name or photo, a large number of prior bookings can lead to more future bookings. This study suggests that P2P trading economy platforms can identify high-quality reviews, motivate users to upload self-defined names or photos, and encourage hosts to use their names and phones to attract more bookings.

在点对点（P2P）交易经济平台中应对安全风险，后客户可能会考虑前客户的决定，构成羊群行为可能发生的环境。本研究旨在调查此类平台中的羊群行为并探索边界条件。该研究确定了以下发现：(1) 先前的住宿预订数量与未来的预订数量呈正相关。(2) 由于更多的预订客户使用自定义而非默认名称或照片，因此加强了预订数量的积极影响。(3) 对于拥有自定义姓名或照片的房东，大量的提前预订可以带来更多的未来预订。这项研究表明，P2P 交易经济平台可以识别高质量的评论，
