本論文研究對象是紀昀《瀛奎律髓刊誤》，並以紀昀的核心觀念當中的「清」作為主要探討對象。研究的方法，則是利用評語派生詞、字頻數等相關統計，來整理出「清」概念的內涵，並且藉此觀察評點的實際概況。紀昀將「清」的派生詞大量使用於評點之中，此現象使我們能夠從主要核心用語「清妥、清穩、清整」；藝術手法「清遠、清圓、清麗、清而豔」；命意創發「清出、清新」；思想「清老、清遒」；二元對辯「清淺、清薄、清弱」等等詞語，窺探紀昀的審美觀點。再者，本論文也從學詩門徑，來談後人對「清」概念的接受。最後，本文亦對方回與紀昀的概念進行比較，指出了「清」概念的強大涵容性。

The text used in the study was Ji Yun（紀昀）'s Yingkui Lusui Kanwu（瀛奎律 髓刊誤）, and the main subject that we focused on was Qing（清）in Ji Yun's core concepts. In order to clarify the concept of Qing, the statistic method was applied to the organization of the derivative and relative words. Therefore, the actual situation of Ji Yun's literary criticism theories became observable. The derivative words from Qing, such as the core terms of Qingtuo（清妥）, Qingwen（清穩）, and Qingzheng （清整）; means of artistic expressions of Qingyuan（清遠）, Qingyuan（清圓）, Qingli （清麗）, and Qing er Yan（清而艷）; and whatever of this category and the like, give us a way to observe Ji Yun's aesthetic perceptions. In addition, the study discussed how the later generations received the concepts of Qing based on poem-composing methods. In conclusion, by comparing the notions of Ji Yun and Fang Hui（方回）, we believed that Qing strongly shows a comprehensive concept among a broader range.
