本文采用2007-2015年我国上市公司治理结构和审计相关的数据,分析了业务复杂度与审计费用的关系以及该关系在不同治理结构下的强弱变化。研究发现两职合一导致了更为严重的代理问题,提升了企业的审计费用。进一步,业务复杂度与审计费用表现为正相关关系,且该关系在两职合一的企业中更为明显。这说明业务复杂度使得管理层更容易隐藏自利动机,两职合一的权力安对企业进行合理监督。
This paper analyzes the relationship between business complexity and audit fees and the changes of the relationship under different governance structures from 2007 to 2015 with the data about the governance structure and audit of listed companies in our country. The study found that the combination of two positions led to a more serious agency problem, raising the audit fees of enterprises. Further, there is a positive correlation between business complexity and audit fee performance, and the relationship is more evident in companies with two positions in one. This shows that the business complexity makes it easier for management to hide the motivation of self-interest, and that the power of one of the two posts should be rationally supervised by the enterprise.
