供应链集中度与审计意见购买

Concentration of Supply Chain and Audit Opinion Shopping

审计意见购买的监管与治理一直是学术界和监管机构所关注的重要问题。本文以2010-2016中国A股上市公司为样本,运用Lennox (2000)的审计意见购买模型,考察了供应链集中度驱动下的审计意见购买及其影响因素。研究发现,供应商-客户集中度越高,公司越可能进行审计意见购买。从审计意见购买动机看,在与供应商或客户议价能力较低的公司中,供应链集中度驱动的审计意见购买行为更显著;从审计意见购买实现的客观条件看,从总所向分所变更时供应链集中度驱动的审计意见购买更易于实现。进一步研究发现,与供应商或客户共享同一审计师能够减少供应链关系压力下的审计意见购买。本文首次从供应链视角研究了审计意见购买的动因及成功实现审计意见购买的影响因素。

The supervision and governance of the opinion shopping have been an important issue for academics and regulators all over the world. Tak- ing Chinese A- share listed firms from 2010 to 2016 as our samples and borrowing the method in Lennox （ 2000）, we investigate the impacts of concen- tration of supply chain on audit opinion shopping. The empirical results show that concentration of supply chain can increase the probability of audit opin- ion shopping. From the motivation of audit opinion shopping, supply-chain-driven opinion shopping is more pronounced when the firm has lower bargain- ing power. From the objective conditions for the realization of audit opinion shopping, supply-chain-driven opinion shopping is more pronounced in office level switching instead of headquarter level switching of audit firm. Furthermore, we find that the common auditor of supply-chain can significantly de- crease supply-chain-driven opinion shopping. This paper firstly provides the motivation of audit opinion shopping and the factors of successful audit opin- ion shonning from the uersuective of sunnlv chain.
