企業資源規劃系統是以財務為基礎的資訊系統，其功能可大幅度縮短企業處理財務會計流程的時間，並且加速財務報表的編製與資訊的即時性與準確性。由於年度財務報告期限的縮短，提升資訊公開的時效已是世界的潮流所需，亦即公開財報資訊的即時性已成企業必要條件之一，因此本文首先探討企業導入ERP系統與財報公告時距的相關性，以了解ERP系統是否可以即時提供決策者有效的資訊，進而使管理當局有能力提前公告財務報告。其次，將以代理理論所衍生出來的盈餘管理作為研究，探討企業是否會因為設置ERP系統後，企業管理階層相對於外部投資人，享有即時取得會計資訊之優勢，並增加資訊不對稱的影響，進而有盈餘管理之動機，並藉以瞭解設置ERP系統是否與盈餘管理產生關聯性的影響。
研究結果發現，(一)企業導入ERP系統會縮短財務報表公告時距；(二)企業導入ERP系統與每股盈餘之交乘效果，不會縮短財務報表公告時距，亦即導入ERP系統與每股盈餘之交乘作用與財報揭露呈正向變動；(三)企業導入ERP系統，對於盈餘管理的操縱幅度會提升；(四)導入ERP系統與每股盈餘之交乘效果，與企業盈餘管理呈現負向變動。
關鍵詞：企業資源規劃系統、財務報表揭露、盈餘管理、代理理論

Enterprise resource planning system is based on financial information systems, its function can shorten the time of the business accounting process to accelerate the preparation of financial statements information in real-time and accuracy. Shorten the period of the announcement of the annual financial statements has become increasingly important in recent years. In this study, we examine whether ERP systems implementations have affected the financial report disclosure date. Agency theory derived from the earnings management as a research and discuss whether because of the set of ERP systems, business management class has immediate access to accounting information advantage, and increase the impact of information asymmetry, and thus the motivation of earnings management, and in order to understand the ERP system is set to the relevance of the impact of earnings management.
The conclusions of this study are presented as follows: (1) ERP system implementations will shorten the financial statements lag；(2) ERP system implementations will not shorten the financial statements lag for positive EPS firms ； (3) ERP system will increase the extent of manipulation of earnings management； (4) ERP system and earnings per share at the turn of synergistic effects negatively to the changes, and earnings management.
