This figure outlines the overall research design used in the bibliometric study. It begins with the selection of the Web of Science Core Collection, specifically the Social Science Citation Index (SSCI), as the data source. The design is structured around four research questions (RQ1 to RQ4), each linked to specific bibliometric methods: bibliographic coupling, co-author analysis, co-occurrence analysis, and conceptual analysis. Corresponding tools employed for analysis include VosViewer, bibliometric.com, and Biblioshiny.
