企業經由資訊揭露提升資訊透明度是資本市場健全的重要因素之一。企業以XBRL技術在網路上揭露財務資訊，可以增進資訊使用者資訊搜尋與處理的效率，提升企業財務資訊透明度。透過XBRL的建立與運用，將使各地區或國家間財務報表擁有共通的語言，進而形成全球資訊供應鏈，促進財務報告資訊的交流，提升全球資本市場的效率性。台灣為了與國際接軌，台灣金管會要求上市櫃公司，於2010年起須採用XBRL格式來製作申報財務報表。希望藉由XBRL技術的採行以提升台灣資本市場的資訊透明度與效率性。
本研究以實證分析探討企業採用XBRL技術是否能提升資訊透明度，降低企業的資金成本，提升公司價值。實證結果顯示，採用XBRL技術的企業舉債資金成本顯著較低，但權益資金成本並沒有顯著差異。可能因為企業資金的貸放者大多為銀行與法人機構，資訊技能的接受與運用能力較佳，比較能享有XBRL互動式資訊所帶來的資訊處理效益。且採用XBRL技術與公司價值具有顯著正向關係。因外部的監督效能提升，提升企業績效增加公司價值。因此，企業以XBRL揭露資訊將可以改善債權人與企業資訊不對稱問題，降低貸放資金的風險，企業的舉債成本因而降低，並擁有較好的公司評價。本研究結果可以提升企業界以XBRL作為資訊揭露技術之意願，以享有較低的資金成本與較佳之公司價值，同時也可以補強XBRL相關參考文獻之不足。

With adopting XBRL for financial reporting on the web, business can eventually find a “common financial reporting language” among regions or nations which can increase communication of financial information, improve efficiency of information search and process, and strengthen transparency of financial information. This study empirically explores whether adopting XBRL can increase information transparency and lower cost and higher value of capital for business. The results of this study show that with adopting XBRL cost of debt is significantly lower and higher value of capital for business but cost of equity capital is not. The possible explanation is that both banks and institutions, major sources of loan capital for business, are more sophisticated in processing information and can benefit more from XBRL. Therefore, XBRL can improve information asymmetry problem between creditors and business, reduce the risk of loan capital , and lower cost of borrowing for business. Taiwan Financial Supervisory Commission mandates all public trade companies and over-the-counter companies to adopt XBRL for filing financial reports in 2010. With empirical support of lower borrowing cost by adopting XBRL, this study is to motive business to adopt XBRL and to fill the gap of literature.
