| Abstract (English): |
This article examines the evolution and complexity of service research, emphasizing the role of meta-analyses in synthesizing findings across diverse studies. It evaluates how meta-analytic methods are used to address heterogeneity in primary studies and to understand the influence of moderators. Using a systematic literature review, the study follows three phases: (1) assembling a dataset of 202 meta-analyses from 1985 to 2024; (2) applying rigorous filtering to ensure quality and relevance; and (3) analyzing the data through coding and keyword-based clustering. Heterogeneity in service research stems from varied contexts and methodological approaches, yet its impact on theoretical and practical insights remains underexplored. This study addresses that gap by examining how heterogeneity should be treated and what it implies for knowledge accumulation. The findings underscore the importance of methodological rigor to improve the generalizability of meta-analytical results. Additionally, understanding the role of moderators is shown to enhance research design and guide future work toward more cohesive, evidence-based practices in service research.

摘要：本文探讨了服务研究的增长及其日益复杂的特点，强调了元分析在整合不同研究结果中的关键作用。本研究旨在评估元分析方法在服务研究领域中的应用，特别是在处理初级研究异质性以及识别调节变量对变异性的贡献方面。通过系统文献综述流程，本研究分三个阶段进行：(1) 收集1985年至2024年间的202项元分析数据；(2) 严格筛选数据以确保其相关性与质量；(3) 通过关键性审查、数据编码与关键词聚类，对研究结果进行分析与综合。服务研究中的异质性可能来源于多样化的服务研究情境，或是使用了不同的方法和模型。然而，我们注意到，关于跨研究异质性如何影响理论与实践见解的理解仍然有限。本研究试图填补这一空白，系统性地探讨如何处理异质性以及异质性对服务领域知识积累的影响。研究强调了在应对异质性过程中保持方法严谨性的必要性，以提升元分析结果的普遍适用性。此外，研究表明，理解调节变量之间的相互作用可以优化研究方法，并使未来研究更好地与循证实践接轨，从而在服务研究领域实现更大的一致性与影响力。 [ABSTRACT FROM AUTHOR] |
