The idea of human territoriality is highly relevant to home-sharing services, which involve the sharing of private space under the sphere of business. To assist examinations of human territoriality in home-sharing contexts, this paper attempted to develop and validate a scale of host territoriality from the perspective of P2P accommodation guests. Four studies with diverse data sources were conducted. The final scale had four dimensions (i.e., accessibility, house rules, signs of ownership, and intrusion) and 18 items. Results of known-group comparisons and a variety of criterion validity tests demonstrated good construct validity. Host territoriality, specified as a superordinate construct, was found to negatively affect guests’ experience satisfaction and intentions to reuse or recommend P2P accommodation rentals. Theoretical and practical implications were discussed based on the findings.

人类领土的概念与家庭共享服务高度相关，其中涉及私人共享业务领域下的空间。为了协助在家庭共享环境中检查人类领土，本文试图从 P2P 住宿客人的角度开发和验证主机领土的规模。进行了四项具有不同数据来源的研究。最终量表有四个维度（即可达性、房屋规则、所有权标志和入侵）和 18 个项目。已知组比较和各种标准效度测试的结果证明了良好的结构效度。发现被指定为上级结构的主人地域性会对客人的体验满意度和重复使用或推荐 P2P 住宿租赁的意图产生负面影响。根据研究结果讨论了理论和实践意义。
