Diffusion of integrated reporting, insights and potential avenues for future research

This study reviews the diffusion of integrated reporting (IR) research. The systematic literature review method is used to review the effects of IR at the organisational level, determinants of IR adoption and integrated report quality (IRQ), assurance on IR, economic consequences of IR/ IRQ, and research design issues to set agendas for future research. The review covers 119 peer-reviewed IR articles published in 36 journals between 2012 and 2021. It finds that the IR literature is dominated by organisational-level studies, but there is limited research on the economic consequences of IR/IRQ, and the findings are inconclusive to date. Further, the factors that determine IR adoption/ IRQ are not conclusive, and there is scarce research on IR assurance. This review contributes to the emerging IR literature and provides valuable insights to the International Integrated Reporting Council (IIRC) in establishing the IR framework as a global reporting norm in practice.
