Grounded in institutional theory, this study provides an overview of the corporate social responsibility (CSR) initiatives of Turkey's 30 largest corporations through a thematic content analysis. The study focuses on the G‐20 member Turkey and investigates the influence of isomorphism mechanisms on the adoption of CSR initiatives in a developing country context. The aim of this study is to integrate Carroll's CSR dimensions, the type of CSR engagement and coercive, mimetic and normative isomorphism mechanisms proposed by institutional theory. Through this integration the study makes a unique contribution to the literature by providing a different perspective. Findings reveal industry characteristics do not influence the selection of CSR initiatives. While business‐to‐business companies focus on CSR activities linked to their core business functions, business‐to‐consumer companies focus on CSR initiatives that are more discretionary, varied and philanthropic. In addition, findings show that multinational corporations implement CSR initiatives at the global level rather than focusing on local needs.
