公司法發展出有限責任原則,為公司設立與經營帶來諸多便利性,但有限責任可能使公司經營的風險移轉至公司債權人,導致不公平的結果。為防止股東濫用有限責任,我國以資本三原則做為我國公司資本規範之準則,期望達到保護債權人之目的。然而資本三原則所創造的形式化資本結構是否發揮了「保障債權人」的功能不乏受到國內外法律學者的質疑,檢討聲浪四起。 本文目的為檢討我國資本三原則的形式化資本結構規定,並搭配較為主流的它國立法例,如美國模範商業公司法、德拉瓦公司法、紐約商業公司法、歐盟商業組織法第二號指令等,作為我國未來資本制度之自由化與現代化的反省與改革參考。 最後,本論文將提出幾點建議:(一)導向非形式化資本結構;(二)統一公司分配資產與股東的標準;(三)提出三個債權人保護措施,包括負責人受託義務、揭穿公司面紗原則與衡平居次原則。Even though the limited liability rule brings much convenience for the establishment and operation of the company, it will transfer the operating risk to the creditors of the company and lead to unfair results. In order to prevent the abuse of limited liability from shareholders, Taiwan exercises the three corporate capital principles as company's capital specification criteria, expected to achieve the purpose of protecting the creditors. However, the function of the protection of creditors created by the three principles structure has been doubted by some domestic and foreign legal scholars.First, the purpose of this thesis is to review the requirements of Taiwan's capital structure through comparing with the U.S. and EU capital structure. Furthermore, the thesis will make a few suggestions: (a) create non-formal capital structure; (b) establish the distribution concept; (c) submit three creditor protection measures, including Fiduciary Duty, the principle of piercing the corporate veil, and the principle of equitable subordination.
