Transformation of the meso-level research landscape in economics: A systematic bibliometric review

Purpose: to update the methodological foundation of meso-level economics research through a systematic bibliometric analysis that identifies and structures its key thematic areas and theoretical and methodological approaches. Methods: the paper employs a systematic bibliometric analysis using the VOSviewer tool to construct terminological maps, cluster data and analyse the dynamics of topics. The present study is grounded in a selection of publications from the Scopus database (2008–2025), which have been filtered by mention of the meso-level of economy. The methodology encompasses a retrospective analysis of the mesolevel concept evolution, the identification of central terms, and the application of а cluster analysis to terminological domains. Results: the context of the development of meso-level economics research is defined. Eight thematic clusters reveal a paradigm shift: from static structures to dynamic transformations, and from theoretical to applied management tools. The sustainable development agenda – particularly its environmental dimension - emerges as central, enabled by digital transformation. Critical gaps include: (1) weak conceptualization of integration forms, and (2) insufficient attention to socio-demographic and geopolitical factors. Stakeholder approaches are essential for harmonizing interests in quasi-integrated structures. The meso-level is redefined as a dynamic space for harmonizing stakeholder interests and resources to enhance interorganizational efficiency. Conclusions and Relevance : the meso-level confirms its role as a pivotal adaptation space for global crises and sustainability. Methodological pluralism and deeper theoretical integration are imperative. The future research should prioritize developing rigorous conceptual frameworks for business integration forms.
