Despite ample research on corporate governance (CG) and corporate social responsibility (CSR), there is a lack of consensus on the nature of the relationship between these two concepts and on how this relationship manifests across institutional contexts. Drawing on the national business systems approach, this article systematically reviews 218 research articles published over a 27-year period to map how CG–CSR research has evolved and progressed theoretically and methodologically across different institutional contexts. To shed light on the full gamut of the CG–CSR relationship, we categorize and explore the nature of this relationship along two strands: (a) CSR as a function of CG and (b) CG as a function of CSR. Through this review, we identify key themes where CG–CSR research has lagged and account for under-explored contexts in this domain. Finally, we put forth a comprehensive agenda for progressing future research in the field.
