CBDCs: A Comprehensive SLR on Worldwide Research Emergence and Methods Used

Abstract

This study conducts a comprehensive systematic literature review (SLR) on Central Bank Digital Currencies (CBDCs) in response to the escalating global demand for digital payments. As CBDCs become increasingly prominent, there is a crucial need to examine the worldwide research landscape, research methodologies employed, and the data utilized in CBDC research studies. Using the Scopus database, a total of 323 articles were initially identified using the keywords “Central Bank Digital Currency” OR “CBDC” in the title. Following a meticulous manual screening process, 169 articles were finalized for inclusion. To assess global research emergence, the study employed R, Biblioshiny, and Excel within the SLR framework. To delve into the research methods and data employed in the literature, the selected studies were categorized into quantitative, qualitative, and mixed-methods approaches. Despite the limitations, this systematic and transparent approach establishes a foundational basis for synthesizing insights into CBDC research trends. By categorizing studies based on their research approaches, this study provides a panoramic view of the CBDC research landscape. The findings contribute valuable insights for researchers, policymakers, and stakeholders, serving as a resource for understanding the dynamics of CBDC research.
