Abstract: The U. S. tariff hikes on Chinese imports, as a significant external tariff shock, amplify operational uncertainty for firms and influence decision-making among contractual stakeholders. This study employs a difference-in-differences (DID)model to examine the impact of external tariff shocks on audit fees from the auditor's perspective. The findings reveal that: (1)External tariff shocks significantly increase audit fees for listed companies. (2)The rise in operational risk and information risk serves as a key transmission mechanism. (3)Heterogeneity tests indicate stronger effects for high-tech firms, export-oriented firms, female and experienced auditors, and auditors with industry expertise or major clients. These findings enrich the literature on audit pricing and trade policy shocks, clarify the mechanisms through which tariffs affect audit practices, and provide insights for regulatory policy-making.

摘要: 美对华加征关税作为重要的外部关税冲击加剧了微观企业的经营不确定性,影响到契约方的决策行为。本文从审计师的视角采用双重差分模型实证考察美对华加征关税对上市公司审计费用的影响。研究发现:(1)外部关税冲击显著提高了上市公司的审计费用;(2)上市公司经营风险和信息风险的上升是上述效应的重要传导机制;(3)在高科技和有出口业务的上市公司、女性和经验丰富的签字注册会计师、审计师更具行业专长和拥有更重要的客户时,外部关税冲击对审计费用的提升作用更为明显。本文的研究结论不仅丰富了审计收费和关税冲击领域的文献,而且厘清了外部关税冲击对审计费用的影响和传导机制,为监管部门制定相应的政策提供重要的参考。
