Board interlock and the diffusion of corporate social responsibility among Chinese listed firms

This study explores the effect of board interlock on the diffusion of corporate social responsibility (CSR) among firms. While existing CSR literature has theorized a variety of institutional and organizational factors that drive CSR, what is lacking is a deeper understanding of how meso-level inter-firm relationships shape firms’ CSR. Using a series of pairwise regressions to examine Chinese listed firms’ CSR activities from 2008 to 2015, we find that board interlock leads to a higher probability of CSR adoption in both firms, and convergence of CSR structures. This interlock effect is however conditioned by some institutional and firm-level factors that enhance/impede the exchange of information between interlocked firms. This study contributes to the CSR literature by filling the theoretical gap on a meso-level mechanism of CSR diffusion and provides some managerial implications for corporate executives who are responsible for designing firms’ social programs.
