<p>In today’s global research environment, the concept of research integrity in business schools has become increasingly important due to rising external pressures and the growing societal impact of business research. While prior studies largely explain breaches of integrity through individual behaviour shaped by regulatory frameworks, the role of organisational culture remains underexplored. The current study addresses this gap by proposing a research integrity culture framework for business schools developed through a systematic literature review and mid-range theorising approach, which adapts an abstract model of organisational culture to a specific context of business schools by identifying mechanisms through which culture can shape research integrity practices. The framework integrates systemic-level and individual level factors, while positioning organisational culture – informed by Schein’s Organisational Culture Model – as a moderator between the two types of factors and researchers’ conduct. In doing so, the study responds to the unique research integrity challenges faced by business schools, including pressure from performance metrics, the need to commercialise research outputs, and to collaborate with industry, which are often overlooked in broader integrity discourses. Theoretically, the study re-conceptualises research integrity culture as a multilevel phenomenon and introduces organisational culture as a boundary condition in the relationship between systemic pressures, individual factors, and research practices. Practically, the framework serves as a diagnostic and design tool for policymakers and managers in business academia to align performance systems, organisational culture, and researcher support mechanisms with research integrity goals</p>
