唐代前期中央官僚組織大體承自於隋,再經太宗初年內部職權的重組,遂開放了唐型政治制度的理想模式。學界對於三省制的討論,雖有過度詮釋的嫌疑,但中書出命,門下審查,尚書執行,一種行政專業分工、層層管理的組織運作型態,被合理的呈現出來。唐六典這一部研究唐代職官最重要的資料,完成後最終雖未頒行,但其職官職權沿革之考証,單位職權範圍之界定,中央官僚各省、寺、監職權性質的提出,使後代研究唐代職官制度之上下管理、左右職權聯繫成為可能。做為一部理想狀態下的典章制度法,六典將秦漢以降,中央官僚組織舊(三公、九卿)、新(三省)機關混融於此書中,形成章程格式釐然具備的準法典。
The central bureaucracy of the early T'ang Dynasty generally followed the Sui Dynasty, and was reorganized by the Taizong early years of internal authority, then opened the ideal mode of Tang political system. Academic discussion of the three provinces of the system might over-interpreted, but a new kind of administrative professional division of work and the type of management operation of the organization that were presented properly. T'ang liu-tien was the most important information in the T'ang Dynasty. It finished finally, although not enacted. It not only researched the evolution of the duty of bureaucrat, but also defined the responsibilities of the three provinces. The central bureaucracy promoted the nature of the responsibilities about the three provinces, the ssu and the chien, so that it was possible for future generations to make a perfect study about the T'ang Dynasty Official System Management. As an ideal state of laws and institutions, T'ang liu-tien mixed the old central bureaucracy (Sangong, Jiuqing) from the Chin and Han dynasties and the new authorities (provinces) in this lawbook, and formed a norm one.
