摘要


我國自1998年開始宣導公司治理的重要性,並制定相關法規,以期能提升各企業的公司治理,其中資訊揭露即為公司治理的重要構面之一。因此,本研究欲探討公司治理如何影響企業之自願性資訊揭露行為,主要著重公司治理中之董事會組成和所有權結構對自願性揭露之影響。研究中使用獨立董事佔董事會的席次比例來做為董事會組成的衡量變數;所有權結構則利用經理人持股比率、大股東持股比率及政府持股比率衡量變數。 本研究樣本選取為2010年台灣上市櫃公司,並採用台灣證券交易所及證券櫃檯買賣中心委託證券暨期貨市場發基金會自2003年設置的資訊評鑑系統之評鑑結果來做自願性揭露的衡量變數。 研究結果發現,獨立董事佔董事會比例和政府機構持股比例和自願性揭露程度間成顯著正相關;大股東持股比例和自願性揭露程度間呈顯著負相關;經理人持股比例和自願性揭露程度間成不顯著之負相關。

並列摘要


Since 1998, Taiwan government has started to promulgate the importance of corporate governance and establish related regulations to promote corporate governance for firm listed in Taiwan Stock Exchange Corporation (TWSE) and Gre Tai Securities Market (GTSM). Information disclosure is considered as one of the major aspects of corporate governance. The purpose of this study is to examine the association between corporate governance mechanism focusing on board composition and ownership structure and the extent of voluntary disclosure. Board composition is measured by the percentage of outside directors in the board; ownership structure is characterized by managerial ownership, blockholder ownership and government ownership. The sample for this study is selected from firms listed on the Taiwan Stock Exchange (TWSE) in year 2010. The degree of voluntary disclosure extent is measured by the ranking results conducted by “Information Disclosure and Transparency Rankings System” launched by Taiwan Stock Exchange corporation and Securities & Future Institute. The empirical results of this study indicate that both the percentage of outside directors on the board and government ownership are positively related to the degree of voluntary disclosure. Blockholder ownership is negatively associated with the degree of voluntary disclosure. However, managerial ownership is not related to voluntary disclosure.
