The Twin Transition and its geographical dimensions: a systematic literature review

The concept of the Twin Transition (TT) – the integration of green and digital transitions – has evolved from a loosely linked policy idea – especially in the EU’s post-COVID-19 recovery agenda – to an emerging topic in academic research. TT research has grown rapidly, focusing on the enabling role of digital technologies in addressing climate challenges and on the environmental impacts of digitalization. Recently, academic interest has turned toward an underexplored aspect: TT’s regional geography. Emerging evidence indicates that the development and adoption of green and digital technologies are shaped by regional characteristics, including local capabilities, institutional settings, and path dependencies. However, systematic understanding of these geographical dimensions remains limited. This paper addresses that gap through a bibliometric analysis of TT-related research with spatial relevance. Using network analysis and bibliographic coupling, the study identifies key research trends, clusters, and gaps. Findings show a fragmented but fast-growing field, with both qualitative and quantitative approaches offering insights across spatial scales. Patterns of scientific output suggest a ‘success-breeds-success’ dynamic, particularly in ICT-strong regions. The paper underscores the importance of place-sensitive policies and localized knowledge in shaping the TT and offers a roadmap for future research into how regional factors mediate this dual transformation.
