在現今臺灣日治時期新文學作品整理上最重要的兩套書：明潭出版社的「日據下台灣新文學」及遠景出版社的「光復前台灣文學全集」中，詩人楊華都是令人印象深刻的一位。原因除了兩套書中，他的詩作都是最多之外，應是他較之彼時詩壇特異凸出的詩風及短暫如謎般的一生。本文僅是試圖解開楊華這些謎團的開頭，單純把焦點聚集在對於楊華作品的身份認定上，推得：(1) 楊華原名應是楊顯達，而非楊建或江夢筆；(2) 楊顯達除楊華筆名外，尚有 (楊) 器人、楊花等；(3) 1927年《臺灣民報》上的得獎詩作〈小詩〉的作者「器人」應為楊顯達，而非江夢筆，等三點。雖然這三點在目前學界有一定共識，卻仍有部份不同的聲音，本文即在前行學人的研究成果及現有的薄弱史料上予以整理爬梳，以為日後延伸研究之基石。

Attempted to resolve these obscurities, the focal point of this article was to identify Yang, Hua’s works. The Assumptions are: (A) Instead of Yang, Jian or Jiang, Meng-Bi, the authentic name of Yang, Hua was thought to be Yang, Xian-Da. (B) Except for Yang, Hua, Yang, Xian-Da had other pen-names including Yang, Qi-Ren and Yang, Hua. (C) Rather than Jiang, Meng-Bi, the author, Qi-Ren, ofthe rewarded poem, Little Poem, published on Taiwan People News in 1927 was supposed to be Yang, Xian-Da. Although the academic circles have reached certain conformity upon the prior three statements, there are still disagreements. Hence, the article was meant to put prior research conclusions in order as well as the slices of existed historical records.
