PurposeThis study explores the impact of institutions, policies, and regulations at the global, national, and sectoral levels on digitalisation within the Italian and Australian wine industries.Design/methodology/approachDrawing on qualitative research data collected from interviews with key personnel in the wine industry, this study shows that both jurisdictions are at a similar stage of emergent digital development despite very different settings.FindingsAccordingly, the authors find that digitalisation is constrained by common policy and regulatory issues emanating at the global and national levels, such as a lack of data infrastructure and data governance, and the need for institutions at the local and regional levels to spur innovation, especially with SMEs.Originality/valueThis is the first study to analyse the role of policy, regulation, and institutional arrangements in digital diffusion using a cross-country comparison of the wine sector.
