Evolution and trends in financial inclusion research : a systematic literature review and bibliometric analysis (2004–2023)

Abstract

This study examines the development and trends in financial inclusion research between 2004 and 2023, with a focus on the trajectory of publication growth, key contributors (including influential authors, journals, and institutions), and dominant themes within the field. A systematic review and bibliometric analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. A total of 1,784 articles were identified from the Scopus database for inclusion. Analytical tools such as VOSviewer and Microsoft Excel were employed to explore publication patterns, citation networks, and thematic concentrations. The findings reveal a marked increase in financial inclusion research, with 2022 recording the highest output, contributing 473 publications. Among scholars, Ozili emerged as a leading author with significant influence in the domain. The Journal of Sustainability (Switzerland) was identified as the most prolific journal, publishing 173 relevant articles, while the University of International Business and Economics in Beijing, China, was found to be the most productive institution. Keyword analysis highlighted recurring themes and revealed underexplored areas, offering promising directions for future research. This comprehensive analysis not only provides insights into the past and current state of financial inclusion scholarship but also identifies gaps that warrant further academic investigation. By offering performance metrics and mapping the evolution of the field, the study serves as a valuable resource for scholars and practitioners seeking to understand emerging research trends and guide future inquiries.
