This study examines corporate social responsibility (CSR) performance among listed family and nonfamily firms in China. Family firms consistently achieve higher CSR scores, with stronger performance observed when led by highly educated, female, or older CEOs, or those with higher compensation. Additionally, family firms in noncoastal regions with strong government-market relations and political stability are more likely to outperform in CSR activities. These firms emphasize charitable contributions, employee welfare, conservative financial strategies, and reputational capital, underscoring their commitment to long-term value creation and highlighting the unique role of family ownership in shaping responsible business practices in emerging markets.
