本文以國民主權原則、民主參與原則、資訊公開原則為理論基礎，運用個案研究法，分析英國大倫敦市議會之運作，論證議會透明化之內涵應包含議員的「議事行為」及「操守行為」兩個構面；至於獲致議會透明化之途徑為「資訊充分公開」。又就大倫敦市議會之運作經驗以觀，除以「政府資訊充分公開」獲致議會透明化外，尚可透過「深化公眾民主參與」進一步提升議會之透明化。而議會透明化可讓立法權強化對行政權之監督量能。

This study employed the principle of national sovereignty, democratic participation, and freedom of the information as its overarching theory, and utilized the methodology of a case study method. By analyzing the London Assembly, this study suggests that the idea of parliamentary transparency includes disclosing legislative procedures and promoting the personal integrity of councilors'. It was found that the best approach to establish parliamentary transparency is to facilitate more than the freedom of the information. In addition to the approach of the freedom of the information, the transparency of parliament could be promoted by engaging more citizens to involve parliamentary agendas in terms of the experience of the London Assembly. In addition, the parliamentary transparency can bring the parliament more power to oversee executive administration.
