The aim of the present study is to analyze an organizational policy model based on corporate social responsibility in oil‑rich regions companies. In terms of its objective, the research is basic–applied, and in terms of its implementation method, it employs an exploratory mixed-method approach (qualitative–quantitative).The statistical population in the qualitative section consisted of 14 managers and experts in the field of social policy-making and corporate social responsibility, including faculty members and managers of oil‑rich regions companies, who were selected purposively. In the quantitative section, the statistical population included 191 managers and experts of the National Iranian Copper Industries Company who were knowledgeable in the field of corporate social responsibility and were selected through simple random sampling.Data collection tools included semi‑structured interviews in the qualitative phase and a researcher‑made questionnaire in the quantitative phase. For data analysis, the qualitative data were analyzed using the grounded theory method with NVivo version 11, while in the quantitative phase SPSS and PLS software were used.The results of the qualitative phase indicated that the extracted concepts consisted of 89 open codes, 30 axial codes, and 15 selective codes, which together form the model of social policies based on corporate social responsibility in the National Iranian Copper Industries Company.The results of the quantitative phase showed that the causal conditions of the CSR‑based social policy implementation model, contextual factors influencing the model, intervening conditions of CSR‑based social policies, consequences of the CSR‑based social policy model, and strategies of CSR‑based social policies constitute the core categories forming the model of social policies based on corporate social responsibility.
