學者咸以為，隋‧李諤的〈上書正文體〉乃提供古文運動前期理論的重要撰作，就作者生平來看，份屬儒者，出身自北朝的李諤在隋文帝朝提出「請正文體」的上書，其背景所關涉的應有西魏時期蘇綽的奏行〈大誥〉、個人儒學思維、文帝的政法理念、以及他個人對文學的認識。在上述背景的激盪下，〈上書正文體〉一文意旨因而呈現出復古、以儒教為依歸，以及文學決定政治等概念，此書的提出，同時也表現出李諤對隋文帝以法領文之嚴厲手段的支持。究其時代意義，則〈上書正文體〉不僅彰顯出隋代初期文學思潮的擺盪，更呈現了李諤意欲以儒學匡正時弊的政治目的；就其影響而言，雖然此書並未扭轉隋代的華麗文風，但此書既蓄養了唐代古文運動的理論動能，更為隋代社會革新留下史料，其價值當不僅止於文學面，它同時也具有社會、歷史的意義
