다국어 초록 (Multilingual Abstract)

The purpose of this research is to analyze if audit committee and full time auditor have any effect on earnings management. Specifically we wanted to find out which has more significant effect on earnings management, audit committee or full time auditor? The research samples were selected from New-Kisvalue. Initially we selected 2.338 samples. We analyzed 1.276(company-year) final samples after eliminating those which have not meet our sample selection criteria. The multiple regression result showed that audit committee decreased accrual based earnings management. However, audit committee does not have any effect on real earnings management. In order to test the effect of audit committee on real earnings management more specifically, we selected only manufacturing companies from the final research samples. The multiple regression result suggests that audit committee decreased real earnings management. We found the same result with the sample data from small companies. The multiple regression result suggests that audit committee decreased accrual based earnings management. Overall research result indicates that audit committee decreased accrual based earnings management. Analyzing the samples consist of manufacturing companies, we found that audit committee significantly decreased real earnings management. Our research suggests that we should strengthen the qualification for the full time auditor in order to satisfy the important corporate governance participants.
