Future directions of R&D internationalization in international business

Abstract

Purpose: This paper aims to provide a focused review of international business (IB) literature on research and development (R&D) internationalization, assessing the progress and proposing future research directions. Design/methodology/approach: Total 167 peer-reviewed articles from IB journals (following the ABS list 2021 from 4* to 2) published between 1996 and 2022 are critically reviewed using a science-mapping approach. This paper used Bibliometrix R-package to analyze the retrieved bibliometric data. Additionally, a strategic diagram was developed to comprehend the maturity stage of various R&D internationalization concepts. Findings: Most studies on R&D internationalization are influenced by perspectives from advanced-economy multinational enterprises (AMNEs), while perspectives from emerging-economy multinational enterprises (EMNEs) are underrepresented. Considering the characteristics of emerging economies, firms from these locations might embark on and develop their R&D internationalization strategies differently. Investigating the emerging economy perspectives will enrich the understanding of R&D internationalization strategies for both AMNEs and EMNEs. Additionally, bringing different underutilized theoretical perspectives will help to untangle the anomalies observed in extant literature. Originality/value: This paper is among the few to scrutinize the IB literature on R&D internationalization by applying a unique combination of bibliometric techniques and a content analysis approach. By complementing existing reviews and providing fresh insights into the phenomenon, it offers a conceptual framework that can be used as a basis for further research on R&D internationalization.
