This study examines the relationship between corporate social responsibility (CSR), earnings management (EM), and the characteristics of chief executive officers (CEOs) within the context of China's economic transformation. Drawing on stakeholder theory and upper echelon theory, this study investigates the influence of CSR on EM and the role of CEO characteristics. The empirical analysis is based on a sample of 1,980 Chinese firm-year observations from the Shenzhen and Shanghai stock markets, between 2013 and 2017. The findings reveal a negative relationship (...) between CSR performance and discretionary accruals (DA), suggesting that higher CSR is associated with lower EM. Moreover, this relationship is more pronounced among firms with highly educated CEOs (postgraduates) and mature CEOs (approaching retirement age). Notably, the negative CSR–EM relationship is strengthened in firms with mandatory CSR reports. This study expands prior research by exploring the impact of CEO characteristics on the CSR–EM relationship, incorporating CEO attributes alongside ownership structures and governance mechanisms. The findings offer insights for organizations in terms of selecting ethically committed CEOs, as well as guidance for shareholders in understanding CEO selection criteria. Furthermore, this study highlights the importance of mandatory CSR disclosure (CSRD) for policymakers evaluating CSR performance according to the disclosure type. (shrink)
