Foodstagramming has grown in popularity within foodservice contexts. While it is commonly seen as a tool for impression management and normative behavior, the influence of social interaction on foodstagramming has received limited attention. This research aims to fill this gap by examining the interplay of social interaction, tie strength with peers, and subjective well-being, through the lens of social presence theory. An explanatory sequential mixed methods design with two empirical studies was conducted. Using a survey design, the Study 1 reveals that the need for social interactions serves as a precursor to foodstagramming benefits and establishes a mediated relationship leading to subjective well-being. Study 2 employs a qualitative inquiry to provide an in-depth understanding of the impact of posting food selfies on individual subjective well-being. It further reveals that sharing food selfies not only influences personal happiness at the moment of posting but also continues to affect subjective well-being over a relatively extended period. This research enriches social presence theory by exploring the sense of presence and community created through vivid food photos and by explaining the different effects of strong and weak ties. It also contributes new insights to the hospitality literature, highlighting the interconnectedness of offline and online experiences, which collectively contribute to customers’ enhanced life satisfaction in a commercial setting.

在微名人餐厅享受乐趣：社交互动、美食图和分享满意度的作用

Foodstagramming 在餐饮服务领域越来越受欢迎。虽然它通常被视为印象管理和规范行为的工具，但社交互动对美食图的影响受到的关注有限。本研究旨在通过社会存在理论的视角，检验社会互动、与同伴的联系强度以及主观幸福感之间的相互作用，从而填补这一空白。通过两项实证研究进行了解释性序贯混合方法设计。通过调查设计，研究 1 揭示了社交互动的需求是美食图益处的先决条件，并建立了一种导致主观幸福感的中介关系。研究 2 采用定性调查来深入了解发布食物自拍照对个人主观幸福感的影响。研究进一步表明，分享食物自拍照不仅会影响发布时的个人幸福感，还会在相对较长的时间内持续影响主观幸福感。这项研究通过探索生动的食物照片所创造的存在感和社区感，并解释强关系和弱关系的不同影响，丰富了社会存在理论。它还为酒店业文献提供了新的见解，强调了线下和线上体验的相互联系，共同有助于提高客户在商业环境中的生活满意度。
