This research chooses the listed companies which contain 4068 observations from 2005 to 2011 and uses Ordinary Least Squares regression method to examine the relationship between auditor tenure , industry specialization and cost of debt capital. The results are summarized as the following :
1. It is significantly negative association between auditor tenure and cost of debt
capital , which means that the longer the auditor partner tenure , the more
understanding for the customers , as a result that the auditors of a customer with a
more extensive audit experience , can effectively detect errors and fraud of the
financial information to enhance the transparency and reliability of the financial
statements , and creditors are willing to reduce the required rate of return , thus also reduce the cost of debt capital by the company.
2. It is significantly negative association between auditor industry specialization and
cost of debt capital , which means that the auditors with industry specialization that
have a wealth of industry knowledge and practices for a particular industry , and
have more abilities to detect fraud of the financial statements. Thus , this indicates
that auditor industry specialization can reduce information asymmetry and agents’
conflict of interest effectively , then creditors are willing to reduce the required rate of return , thus also reduce the cost of debt capital by the company.
3. The longer auditor tenure and the auditor with industry specialization have the
greater degree of control rights deviation , reducing the cost of debt capital by the
company.
