Between legitimacy and nonconformity costs: The influence of board interlocks on CSR performance

This study examines how board interlocks influence firms’ CSR performance in China through a legitimacy-nonconformity cost framework. It aims to explain CSR heterogeneity by analyzing network positions (centrality/structural holes) and network pluralism (central/local government connections) as contingencies. Results indicate that board interlocks enhance CSR performance, with central network positions or central connections strengthening firm responses due to higher nonconformity costs, while local connections weaken this effect. By integrating social cost mechanisms with legitimacy perspectives, this study advances institutional theory in explaining CSR performance heterogeneity and offers novel insights into how board interlocks shape non-market strategies in emerging markets.
