Abstract

This study's purpose is to verify how the periodically designated auditor in the recently implemented periodic auditor designation system affects audit quality. In this study, hypotheses were established by reviewing previous studies, and 980 samples of 2019 and 2020 were selected for KOSPI-listed companies. Dechow & Dichev (2002)'s accrual quality was used as the dependent variable, and the effect of whether or not a company was periodically designated as an auditor and whether or not a Big 4 auditor was selected was empirically analyzed. As a result of the analysis and correlation analysis, a statistically significant difference was confirmed in the quality of the dependent variable accrual and the independent variable designated auditor (PA). However, as a result of the regression analysis model 1, it was found that the designated auditor was not significant, but it was confirmed that there was a significant difference in the control variables. Further analysis confirmed the difference in audit quality according to the Big 4 auditors. This study is significant in that it is a study that uses empirical data to study the effect of audit quality and the selection of regularly designated auditor companies after the introduction in 2019 and 2020. Due to the non-disclosure of government-designated companies, there is a limit that there may be a difference from the selection based on the researcher's published selection criteria.

본 연구는 최근에 시행된 주기적 감사인지정제의 주기적으로 지정된 감사인이 감사품질에 어떠한 영향을 미치는 지 검증하고자 한다. 본 연구에선 선행연구를 검토하여 가설을 설정하고, 코스피상장기업을 대상으로 2019년과 2020년의 980개의 표본을 선정하였다. 종속변수로는 Dechow & Dichev(2002)의 발생액의 질을 사용하였으며, 주기적 감사인 지정 기업 여부와 Big4 감사인 여부에 따른 영향을 실증분석한다. 분석결과, 상관관계분석결과에서 종속변수 발생액의 질과 독립변수지정 감사인 여부(PA)는 통계적으로 유의한 차이가 확인되었다. 그러나 회귀분석모형 1의 분석결과, 지정 감사인 여부는 유의하지 않은 것으로 나타났지만 통제변수들에서는 유의한 차이가 있는 것으로 확인되었다. 그리고 추가적인 분석에서 Big 4 감사인에 따른 감사품질의 차이를 확인할 수 있었다. 본 연구는 실증자료를 사용하여 2019년과 2020년의 도입된 시점 이후의 주기적 지정 감사인 기업의 선정과 감사품질의 영향을 연구한 연구라는 데 그 의의가 있다. 정부의 지정기업 비공개로 인하여 본 연구자의 공시된 선정기준에 의한 선정과는 차이가 있을 수도 있다는 한계가 있다.
