The role of blockchain for trade in global value chains: A systematic literature review and guidance for future research

Blockchain technology has received increasing attention from academia, practitioners, and policymakers alike for its potential to disrupt business processes and structures of trade in global value chains (GVC). Amidst the ongoing digitization of economies and societies, blockchain holds promise for addressing unresolved challenges. However, current research on this topic primarily consists of either abstract conceptual work or case studies. To bridge this gap, our study conducts a systematic literature review, aiming to comprehensively explore and structure the realm of blockchain and its impact on international trade. Key research questions explored include: What role do blockchain innovations play in facilitating trade within GVC? Additionally, what are the primary barriers hindering the adoption of blockchain innovations in trade within GVC? Our main contribution lies in categorizing these applications into five distinct categories: Trade Documents; Trade Finance; Trusted Real-Time Information Sharing; Provenance; and Sustainable GVC. Contrary to portraying blockchain innovations as a panacea or universal solution, our findings highlight the technologies' potential rather as a core technological infrastructure when integrated with complementary technologies such as the Internet of Things. Moreover, we identify 11 significant barriers to blockchain adoption in international trade, underscoring the need for concerted efforts to address them. From these insights, we derive implications for policymakers and practitioners, and propose avenues for future interdisciplinary research.
