Innovation in Banking: A Bibliometric Lens on Open Innovation

Abstract

The purpose of this study is to explore the academic literature on open innovation in banking, mapping its volume, growth, and geographic spread, identifying influential authors, journals, and publications, analysing its intellectual structure, and outlining emerging research themes. We employ VOSviewer and Bibliometrix to analyse 96 publications available in Scopus, published between 2008 and 2024. The analysis reveals distinct research streams and highlights gaps for future exploration. The literature shows limited integration between open innovation theory and innovation studies in banking. Empirical research in banking often lacks theoretical grounding, while innovation studies overlook the sector's specificities. Bridging these fields through interdisciplinary work could offer deeper insights and practical value for managers in the area of open innovation in banking.
