The Metaverse is at the vanguard of the impending digital revolution, with the potential to significantly transform industries and lifestyles. However, in 2023, skepticism surfaced within industrial and academic spheres, raising concerns that excitement may outpace actual technological progress. Interoperability, recognized as a major barrier to the Metaverse's full potential, is central to this debate. CoinMarketCap's report in February 2023 indicated that of over 240 metaverse initiatives, most existed in isolation, underscoring the interoperability challenge. Despite consensus on its critical role, there is a research gap in exploring the impact on the Metaverse, significance, and developmental extent. Our study bridges this gap via a systematic literature review and content analysis of the Web of Science (WoS) and Scopus databases, yielding 74 publications after a rigorous selection process. Interoperability, difficult to define due to varied contexts and lack of standardization, is central to the Metaverse, often seen as a digital ecosystem. Urs Gasser's framework, outlining technological, data, human, and institutional dimensions, systematically addresses interoperability complexities. Incorporating this framework, we dissect the literature for a comprehensive Metaverse interoperability overview. Our study seeks to establish benchmarks for future inquiries, navigating the complex field of Metaverse interoperability studies and contributing to academic advancement.

翻译：元宇宙处于即将到来的数字革命前沿，具有显著改变行业和生活方式的潜力。然而在2023年，产业界和学术界出现了质疑声浪，担忧对其的热情可能超越了实际技术进步。互操作性被公认为实现元宇宙全部潜力的主要障碍，是当前争论的核心。CoinMarketCap在2023年2月的报告指出，在240多个元宇宙项目中，大多数处于孤立状态，这凸显了互操作性挑战。尽管对其关键作用已形成共识，但关于互操作性对元宇宙的影响、重要性及发展程度的研究仍存在空白。本研究通过系统文献综述和对Web of Science（WoS）及Scopus数据库的内容分析填补了这一空白，经过严格筛选最终获得74篇文献。互操作性因语境多样且缺乏标准化而难以定义，但作为常被视为数字生态系统的元宇宙的核心要素，其复杂性可通过Urs Gasser提出的技术、数据、人力与制度四维框架进行系统解析。基于该框架，我们对现有文献进行剖析，以形成对元宇宙互操作性的全面概览。本研究旨在为未来探索建立基准，厘清元宇宙互操作性研究的复杂领域，并推动学术发展。
