This study surveys prior studies on corporate social responsibility (CSR) in Korean firms that have been conducted between 2000 and the present. It introduces how Korean researchers define CSR conceptually and develop CSR-related theories. We then discuss how CSR affects Korean firms and stakeholders by comprehensively reviewing prior studies. To this end, we collect and categorize CSR-related papers by subtopics, such as CSR concept, firm value, cost of capital, risk, compensation and ownership structure, and review the research results by topic. We then also review studies on responsible investment (RI). Lastly, we suggest topics and directions for future research.
