This chapter presents a bibliometric and content analysis of research on collaborative governance and stakeholder engagement within public administration and policy. Using data from the Web of Science (1997–2024), it maps the field’s intellectual structure, key authors, journals, and thematic developments. The methodological approach combines bibliometric techniques (co-citation, keyword co-occurrence, and collaboration networks) with content analysis and topic modeling applied to abstracts. Results show that the literature is heavily centered on governance structures, participation, and policy implementation. However, core functional processes, particularly decision-making and problem-solving, remain conceptually and empirically underexplored. Although collaborative problem-solving is frequently mentioned as a goal, few studies explicitly examine how decisions are made or how problems are framed and addressed in collaborative settings. The chapter highlights this as a persistent theoretical gap. It argues for incorporating insights from decision science, negotiation theory, and organizational learning into collaborative governance research. Addressing this gap is crucial for advancing the field’s explanatory power and practical relevance in tackling complex public problems.
