This study explored the multidimensional influence of high reputation on corporate social responsibility behaviors from the “report disclosure”, “report whitewashing”, and “actual performance” perspectives. The study found that a high reputation may trigger high expectations and strict supervision among stakeholders, which may cause those companies with high reputations to disclose high-quality CSR reports and improve the quality of their CSR performance. The results also indicated that, under the influence of a reputation-constraining mechanism, the degree of whitewashing in the CSR reports of high-reputation firms is significantly lower than that of others. This study focused on facilitating a better understanding of the influence of organizational reputation on organizational behavior and providing theoretical support and practical insights regarding the improvement of the effectiveness of corporate social responsibility governance.
