住宿作為旅行活動的核心部分，旅客行為變化對其產生的影響尤為明顯。然而，關於驅動這些行為變化的潛在因素，特別是在環境可持續性方面，目前的了解仍然有限。點對點住宿（例如Airbnb）作為飯店業的新類型，其創新的住宿方式和共享經濟特性引發人們的廣泛關注。與傳統酒店不同，它們提供客製化的體驗，促進房東與客人之間的直接互動，以獨特的方式影響客人的行為。
本次研究旨在通過對24位來自全球且具有豐富住宿經驗的旅客進行深入訪談，並使用歸納法，解釋他們行為變化的根本原因。通過對不尋常行為的關鍵動機和觸發因素的討論，研究為制定行為指引和政策提供了可操作的見解，促進住宿行業的環境可持續發展。

Hospitality, a cornerstone of travel activities, is significantly impacted by changes in guest behavior. However, the understanding of the underlying factors driving these behavior changes, particularly concerning environmental sustainability, remains limited. As a new type within the hospitality industry, Peer-to-peer (P2P) accommodations, such as Airbnb, have garnered widespread attention due to their innovative lodging methods and sharing economy characteristics. Unlike conventional hotels, these accommodations offer more personalized experiences and facilitate direct interactions between hosts and guests, which can uniquely influence guest behavior.
This study seeks to elucidate the fundamental reasons behind guests' behavior changes through in-depth interviews with 24 globally experienced travelers, employing inductive approach. By identifying key motivations and triggers for unusual behaviors, this research provides actionable insights for developing targeted guidance and policies aimed at promoting environmentally sustainable practices within the P2P accommodation sector.
