감사인의 경영자문서비스 가치에 대한 재해석：기업생산성을 중심으로

[Purpose]This paper examines whether auditors can affect the productivity of audited firms when non－auditing service was concurrently provided with auditing service. Many prior literatures about non－auditing service assumes that the possibility of declining auditor’s independence probably happen. However, competing opinions suggest that providing both auditing and non－auditing service can promote effectiveness and efficiency when auditors providing their clients business consulting. Accordingly, this paper has some different point of view about non－auditing service. This paper tries to see the matter from clients’ point of view. Therefore, this paper suppose that clients who buy auditors’ non－auding service can solve various problems in business and promote their effectiveness and efficiency in operating their business by taking auditors’ advanced consulting. [Methodology]The study sample is composed of 3,867 firms with both auditing service and non－auditng service, listed on the Korea Stock Exchange(KSE) in 2011 and 2017. This study uses five regression model(main test and sensitivity analysis) to examine the association between non－auditing service and three aspects of firms’ productivity. The non－auditing services include the ratio on management consulting service fee occupying in the revenue from audited firms. [Findings]According to the result of examination, the ratio of non service fee occupying in the revenue from audited firms effect on the firms’ productivity. In addition to, tax consulting service fee which is kind of non－auditing service has not effect on firms’ productivity. The positive relation between firms’ productivity and non－auditing service is more manifested when the auditors are BIG4 auditors. [Implications] The findings imply that the provision of MAS contribute the productivity process of audited firms. Auditors would devote more efforts and hours on the non－auditing service for clients who pay high fees because the client are more important for them. This suggests that the increase decrease in corporate performance is related to the increase in non－audit fees.
