Abstract
Amid growing societal and scholarly interest in the interplay between sustainability transformation (ST) and digital transformation (DT), this study conducts a systematic literature review to advance the understanding of twin transformation (TT). Analyzing 59 peer-reviewed articles, this review makes three key contributions: (1) It synthesizes the current state of TT research, uncovering critical gaps, including limited sectoral diversity, inconsistent terminology, and the dominance of digitally driven TT perspectives; (2) it proposes a synergy-based framework illustrating the dynamic interdependencies between DT and ST; and (3) it outlines future research directions to address theoretical and empirical challenges and to deepen the exploration of TT. This study provides a foundational agenda for researchers and practitioners aiming to integrate and optimize the twin transformation of digitalization and sustainability.
