本論文目的在探討摯虞對劉勰文體論的影響，並深入比較其異同之點，以窺知我國古典文論在魏晉南北朝的承傳與開展。所依據的原典以《文章流別論》十八條佚文和《文心雕龍》五十篇為主。全篇分七節，除前言、結語之外，復針對「進行文體分類」、「追溯文體源流」、「闡釋文體名義」、「標舉文體楷模」、「分論文體特點」等五個方面爬羅剔抉；經過比勘驗證，得知摯虞確有突破前人的觀點，雖然其書亡佚，但其文體論精華已被劉勰充分吸收而得以保存下來。

　　　　　This paper examines the impact of Jyh yu (?- 311) on Liu Xie's (464-522) study on literary genres through a comparison between their approaches and aims at a better understanding of the development of literature studies in early China. The objects of study are the 18 remaining sections in Jyh's the literary Genres and Their History and the 50 sections in Liu's the Literary Heart and the Carvings of Dragon. The paper has seven chaptes. In addition to the introduction and conclusion, the main body is devoted to the comparison of the two writers in terms of their (a) classification of genres, (b) tracing of the origins of genres, (c) naming of the genres, (d) provision of examples, and (e) discussion of the genre characteristics. The result of the study indicates that, although most of his works are on loner available at present, Jyh indeed had certain original ideas on literary studies, which were adopted by Liu and consequently preserved as a part of our cultural heritage.
