Open and Digital Innovation: Intellectual Structure, Global Trends, and Future Research Directions

Abstract

Advancements in open innovation and digital innovation have reshaped how firms manage their innovation processes. This study investigates the intellectual structure of current open innovation and digital innovation research, reporting on a scoping review using bibliometric and science mapping techniques. Through analysis of 261 journal articles published between 2015 and 2025, three research clusters were identified: (1) digital innovation and industrial research, (2) sustainability-driven strategic innovation, and (3) collaborative decision-making. The study highlights the significant growth in academic output and emphasizes the reciprocal relationship between digital transformation and open innovation, particularly within SMEs and platform-based ecosystems. Gaps in current research are identified in the contexts of digital product ecosystems, decision-making in innovation networks, and ethical considerations. This study provides both theoretical and practical insights for innovation management, emphasizing sustainability and platform-centric business models.
