近幾年全球企業的會計舞弊案件不斷，如2001年起美國爆發了安隆(Enron)、世界通訊(WorldCom)、美國國際集團(AIG)案；日本近年來則有佳麗寶 (Kanebo)、奧林巴斯(Olympus)、東芝(Toshoba)等財務報表不實、舞弊與醜聞事件。這些財務報表舞弊事件造成股市衝擊與投資大眾恐慌，使得投資大眾對於企業所編製財務報表的可靠性與真實性產生莫大質疑。編制財務報表之目的係提供財務報表使用者有關企業財務狀況與經營成果的資訊，以協助報表使用者制定投資及授信決策，所以，由公司管理當局出具之財務報表，其攸關性及可靠性對社會大眾而言是相當重要的。
然而我們都知道財務報表的編制，除了須遵循一般公認會計原則外，涉及許多人為的判斷與估計，經理人是否會為了某些壓力或為了達到某些目的，又或者是對某些評估過於樂觀而採取較為激進的會計方法編制報表，導致日後財務報表重編。本研究針對經理人過度自信這個人格特質對財務報表編製與財務報表品質的影響，尤其是經理人過度自信與財務報表重編之關聯性。
本研究以2005年至2015年台灣上市櫃電子工業公司為樣本，探討經理人過度自信與財務報表重編之關聯性。實證結果顯示，經理人過度自信與財務報表重編未呈現顯著正向關係，表示經理人過度自信並不是導致企業財務報表重編的重要因素。另，本研究發現經理人愈是過度自信，其公司之經營績效與成長機會愈高，亦即越是過度自信之經理人其經營管理能力越高，公司報表品質也越好，從而經理人過度自信並不意謂財務報表重編之機率高。

關鍵字：過度自信、財務報表重編

Continued global corporate accounting fraud cases in recent years, such as Enron, WorldCom, United States International Group (AIG), Kanebo, Olympus, Toshiba, false financial statements, fraud and scandal, from 2001 in United States and Japan. These financial statements fraud caused the stock market shock, panic of the investing public, makes the investing public for the preparation of the financial statements of enterprises the reliability and authenticity, and had a great question. Purposes of the preparation of the financial statements provides financial statement users on an enterprise''s financial position and operating results information, report the user to help them plan investment and credit decisions, so management issued by the company''s financial statements, its relevant and reliability is very important for the community.

However, we all know that the preparation of the financial statements, in addition to follow generally accepted accounting principles, involving many people make their judgments and estimates that CEOs for some pressure or to achieve certain goals, or for some accounting method of assessment was too optimistic and has adopted a more radical statements, leading to restating in financial statements. This study research CEO’s overconfident personality traits influence on the quality and preparation of financial statements, especially the relevance of CEO overconfidence and financial report restatements.

Based on a sample of Taiwanese listed companies in the electronics industry from 2005 to 2015, this study investigates the relationship between CEO overconfidence and financial report restatements. Empirical results show that there’s no significant positive relationship between CEO overconfidence and financial report restatements. It’s means that CEO overconfidence is not an important factor in the financial report restatements. Further, this study found that the more overconfident CEO, the higher business performance and growth opportunities of the company. That is, the more overconfident CEO, the better quality of company’s financial report and CEO overconfidence does not mean that the financial statements exist high risk.

Key words: Overconfidence, Restatements
