<![CDATA[Public-sector innovation increasingly depends on the institutional and organizational capacities of governments to respond to complex service demands, technological change, and evolving governance environments. This study maps the development, scholarly structure, intellectual foundations, research fronts, and conceptual evolution of research on institutional capacity and public service innovation in local-government and related public-sector settings. An integrated bibliometric-scientometric design was applied to 73 Scopus-indexed Articles and Reviews published between 2008 and 2026. Performance analysis, co-authorship analysis, co-citation, document bibliographic coupling,author-keyword co-occurrence, thematic mapping, thematic evolution, and overlay visualization were conducted using Bibliometrix/Biblioshiny and VOSviewer. A purposively selected 26-publication full-text interpretive subset was used to validate major intellectual clusters, foundationalcontributions, and emerging themes. The findings show a rapidly expanding but still fragmented field, with comparatively sparse international collaboration and multiple interrelated research fronts. Bibliographic coupling identified eight connected research clusters, of which six majorclusters centered on innovation-capacity assessment, leadership and administrative context, technological capacity, dynamic capabilities, learning and governance, and collaborative capabilities. The conceptual core remains anchored in public-sector innovation, innovation capacity, dynamic capabilities, and public value, while recent research increasingly emphasizes digital government, digital transformation, artificial intelligence, IT governance, and institutional readiness. The study contributesan integrated knowledge map showing how capability-based Public Administration research is evolving toward more adaptive, digital, collaborative, and governance-oriented interpretations of public-sector innovation.]]>
