Abstract

One of the methods of securing the reliability of accounting information is maintaining high audit quality. The first step of improving audit quality is lowering audit engagement risks. Thus, this study analyzed the relationship between the characteristics of accounting firms and audit engagement risks based on the Bayesian Network. For this, Markov Blanket, the minimum explanatory variable set, which affects audit engagement risks, was presented, and based on the drawn causal relationship, sensitivity analysis was conducted to verify the characteristics of accounting firms, which affect audit engagement risks. The existing preceding research that used multiple regression analysis presumes the linearity between explanatory variables and dependent variables, so there was a limit in drawing the relationship between explanatory variables. Therefore, this study figured out the interdependence between variables using the General Bayesian Network and examined the impact that each variable has finally on audit engagement risks that affects the audit quality. The results of this study would greatly contribute to improving the efficiency of the supervisory task by allowing a supervisory institution to identify an accounting firms that does not manage audit engagement risks properly and to improve the supervision of the accounting firms in advance. In addition, this study will be used as a reference when a supervisory institution would improve the system related to audit quality by presenting the characteristics of accounting firms related to the audit quality.

재무정보의 신뢰성을 높이는 가장 좋은 방법 중 하나는 양질의 감사품질을 유지하는 것이다. 양질의 감사품질을 유지하는 첫 번째 단계는 감사계약체결위험을 낮추는 일일 것이다. 이에 본 연구에서는 베이지안 네트워크를 활용하여 회계법인의 속성과 감사계약체결위험간의 관계에 대해 살펴보고자 한다. 이를 위해 감사계약체결위험에 영향을 미치는 최소한의 설명변수 집합인 마코브 블랭킷을 제시하였으며, 도출된 설명변수간의 관계를 바탕으로 민감도분석을 통해 회계법인의 속성과 감사계약체결위험간의 관련성을 분석하였다. 기존의 선행연구에서 사용한 회귀분석은 독립변수와 종속변수간의 선형성을 가정하였기 때문에 독립변수간의 관계를 도출하는데 한계점이 있었다. 이에 본 연구에서는 일반 베이지안 네트워크를 바탕으로 변수간의 상호의존성을 파악하고 각 변수들이 감사품질에 영향을 미치는 감사계약체결위험에 어떠한 영향을 미치는 지를 검토하였다. 본 연구의 결과는 감독기관이 감사계약체결위험을 제대로 관리하지 못한 감사인을 사전에 식별할 수 있기 때문에 감리의 효율성을 높일 수 있다. 또한 본 연구는 감독기관이 감사품질과 관련된 회계법인의 속성을 파악함으로써 감리제도의 미비점을 개선할 수 있다는 점에서 공헌점이 있을 것이다.
