链主审计风险与链上企业信息披露质量OA

In supply chain networks,chain leader enterprises serve as core nodes whose audit risks not only affect their own operational status but may also transmit to upstream enterprises through multiple mechanisms,thereby influencing their in-formation disclosure quality.Using A-share listed companies from 2012 to 2023 as a research sample,this study empirically examines the impact of chain leader audit risks on upstream enterprises' information disclosure quality and its underlying mechanisms.The findings reveal that audit risks at chain leader enterprises signifi-cantly reduce information disclosure quality among upstream firms.Mechanism tests demonstrate that these risks negatively affect disclosure quality through risk transmission effects,information dissemination effects,and behavioral contagion effects.Further analysis indicates that such adverse impacts are more pronounced when chain leader enterprises are audited by non-"Big Four"accounting firms,ex-hibit lower levels of digital transformation,or involve manufacturing enterprises in the supply chain.This study enriches research on the economic consequences of au-dit risks at chain leader enterprises and elucidates how such risks propagate through supply chain networks,providing empirical evidence and policy insights for optimizing supply chain information environments and enhancing information dis-closure quality across upstream enterprises.
