Several studies demonstrate that Corporate Social Responsibility (CSR) is becoming a dominant issue in both research and companies’ management due to stakeholders’ pressure. The identification of internal and external drivers and barriers is an initial stage of the corporate social responsibility implementation. The study aims to identify and analyze the drivers and barriers of CSR in Saudi Arabia’s private organizations. For this purpose, primary data were collected using a survey questionnaire that was administered to a representative sample of companies from different sectors in Saudi Arabia. The results show that the main drivers behind the adoption of CSR among Saudi companies are improvement of corporate image, ethical/moral commitment, and to some extend customers’ requirements and risk management. The findings of this study also suggest that there are important barriers hindering the adoption of corporate social responsibility. Among these, the lack of management commitment and the lack of investors’ interests together with the lack of economic resources and lack of employees’ competencies are the most prominent. The findings of this study not only contribute to a deeper understanding of CSR drivers and barriers, but could also encourage firms’ managers and stakeholders to improve CSR activities for more effective implementation.
