内容摘要

Customer firms strategically disclose relationships with environmentally responsible (“good”) suppliers while concealing associations with less sustainable (“bad”) suppliers. We demonstrate that this green-induced nondisclosure for unsustainable suppliers hinders the green transition of supply chains by deterring the positive influence that customer firms can exert on their suppliers’ environmental performance. Notably, customer firms achieve improved environmental performance at the expense of their suppliers’ environmental profiles. To establish causality, we exploit two regulatory shocks to the incentives of customer firms to avoid environmental risks. Our cross-sectional analyses show that our baseline results vary regarding three types of common stakeholders,suppliers’ environmental pressure, and customer inhibition. Moreover, further analysis reveals the real effects of green-induced nondisclosure. Overall, these findings provide critical insights into the consequences of strategic disclosure and its implications for supply chain sustainability management.
