本文試圖從《這隻斑馬This Zebra》附錄的自剖文章與集中幾首歌詞的分析，整理「李格弟」的身份意義，說明夏宇不斷自我突破的詩歌意圖，事實上同樣實踐於《這隻斑馬This Zebra》中，發現其嘗試以「靡靡之音」反抗「詩」的歧義與固定位置。本文主要採用佛洛依德精神分析學說裡的「群體心理學」概念，觀察夏宇創作意識的幽微曲折表現，並且對照前行研究的既有論點，從中闢出一條心理分析的詮釋蹊徑。本文認為「李格弟」從詞人的地位、詩人夏宇的創作分身，迄今已逐漸壯大成為足以與夏宇分庭抗禮的另一個主體，最終並被賦予「詩人」身份。

This paper attempts to analyze the ＂Lee Gedi＂ the identity of meaning, the object is ＂This Zebra＂'s self-sectional articles and lyrics. This paper argues that Xsiu-Yu's continuous self- breakthrough poetry intention, in fact, the same practice in ＂This Zebra＂, I found Xsiu-Yu attempt to use ＂obscene songs＂ revolt ＂poetry＂. This paper mainly uses the Freudian psychoanalytic theory in the ＂Mass Psychology＂ concept, and expand dialogue with previous studies, looking forward to find a psychoanalytic interpretation of the path. This paper concluded that ＂Lee Gedi＂ has gone from ＂song writer＂, ＂another Xsiu-Yu,＂ and grew to become enough to rival Xsiu-Yu another subject, and was given ＂poet＂ status.
