【摘要】 贸易不确定性持续上升，对企业的发展经营提出新的挑战。本文以2015-2020年的A股上市公司为样本，运用多期双重差分（DID）模型，将2018-2020年被列入“实体清单”作为外生事件，检验了贸易不确定性对我国相关企业审计质量的影响及机制。研究表明，贸易不确定性能够“倒逼”相关企业提高审计质量。进一步分析发现，贸易不确定性对非“百强事务所”审计的企业、行业集中度高、科技水平低的企业表现了更强的审计质量激励作用，作用机制主要通过减少企业的代理成本和提升媒体关注度来实现。本文探究了贸易不确定性与审计质量的关系，为应对贸易不确定性提供了经验证据。更多还原

【Abstract】 Trade uncertainties continue to rise, posing new challenges to firms’ development and operation. Taking A-share listed firms from 2015 to 2020 as samples, this paper uses the multi-period difference-in-differences(DID)model, takes “the entity list” from 2018 to 2020 as an exogenous event, and tests trade uncertainty impact and mechanism on the audit quality of relevant Chinese firms. The research shows that the rise of trade uncertainty can force relevant firms to improve their audit quality. Further analysis shows that trade uncertainty has a stronger incentive effect on audit quality for firms audited by “non-top 100 firms”, firms with high industry concentration and low technology level. This mechanism is mainly realized by reducing firms’ agency cost and increasing the media attention. This paper explores the relationship between trade uncertainty and audit quality, and also provides empirical evidence for dealing with the trade uncertainty.更多还原
