High academic interest and numerous theoretical and practical studies on service systems and service ecosystems, paired with the accelerated evolution of the service (eco) system concept, have resulted in complex research in this field. Multiple perspectives from which service systems were studied added to this complexity and inadvertently produced conceptual confusion regarding service (eco) systems. This literature review addresses this confusion by focusing on the evolution of service systems to service ecosystems to consolidate and clarify the field. Therefore, this article's purpose is to systematise the extant research on service (eco) systems and indicate future research directions based on the analysis. Specifically, the article systematically reviews 770 publications on service (eco) systems from 2020 and earlier and identifies the main research topics (focusing on service [eco] systems’ constituent elements, inherent processes, and outcomes), theoretical perspectives, and bridging elements, and suggests future research based on the review results. The article concludes by providing a foundation for continued research emerging from the analysis, with emphasis on five aspects that may stimulate new avenues of research: service ecospheres, service ecosystem simplicity, failures of service ecosystems, paradox in service ecosystems, and panarchy and service ecosystems.

服务系统向服务生态系统的演变：文献综述

对服务系统和服务生态系统的高度学术兴趣和大量的理论和实践研究，加上服务（生态）系统概念的加速演进，导致了该领域的复杂研究。研究服务系统的多个视角增加了这种复杂性，并无意中产生了关于服务（生态）系统的概念混淆。这篇文献综述通过关注服务系统向服务生态系统的演变来巩固和澄清该领域，从而解决了这一困惑。因此，本文旨在系统化现有的服务（生态）系统研究，并在分析的基础上指明未来的研究方向。具体来说，文章系统回顾了 2020 年及之前关于服务 (eco) 系统的 770 篇出版物，并确定了主要研究主题（关注服务 [eco] 系统的构成要素、内在过程和结果）、理论观点和桥接要素，并建议未来的研究基于审查结果。文章最后为分析中出现的继续研究奠定了基础，并强调了可能激发新研究途径的五个方面：服务生态圈、服务生态系统简单性、服务生态系统的失败、服务生态系统中的悖论以及泛滥和服务生态系统. 并根据审查结果提出未来的研究建议。文章最后为分析中出现的继续研究奠定了基础，并强调了可能激发新研究途径的五个方面：服务生态圈、服务生态系统简单性、服务生态系统的失败、服务生态系统中的悖论以及泛滥和服务生态系统. 并根据审查结果提出未来的研究建议。文章最后为分析中出现的继续研究奠定了基础，并强调了可能激发新研究途径的五个方面：服务生态圈、服务生态系统简单性、服务生态系统的失败、服务生态系统中的悖论以及泛滥和服务生态系统.
