시스템 교체 주기가 회계정보투명성에 미치는 영향에 관한 연구

This study examines how the passed years after ERP system adoption is associated with transparency of accounting information. Discretionary accruals can be viewed as a proxy of the likelihood that fraud or errors occur. Therefore we examine the relation between ERP system adoption period and discretionary accruals. And we investigate whether BIG4 auditors take into account ERP system adoption period, a proxy for the information risk associated with transparency. The analysis results shows the significant positive association between ERP system adoption period and discretionary accruals. This result means that ERP system adoption period lowers transparency of accounting information. Second, BIG4 auditor is negatively associated with discretionary accruals. The study makes mainly some contributions. Different to precedent works which focus on usefulness of accounting information, this study attempts to provide empirical evidence for ERP system adoption period and transparency of accounting information. The results of this paper suggest that ERP system adoption period gives a good signal in terms of transparency of accounting information. Therefore, this study is expected to provide implications to regulators, investors, company that interested in ERP system.
