This study investigates the relationship between board composition and corporate social responsibility (CSR) performance. Specifically, we examine the impact of board composition (aspects like political experience, academic experience, overseas background, and gender diversity) on CSR performance. We test our hypotheses using data collected from 839 Chinese public firms during the period from 2008 to 2016. Applying generalized least squares regression, the study shows that the political experience, academic experience, and overseas background of the board members are positively related to the firm's CSR performance. Moreover, we discuss the distinctive relationship between gender diversity and CSR performance in the context of Chinese culture. We extend the CSR literature by examining unique aspects of board composition in the Chinese context and offer fruitful implications for both scholars and practitioners.
