本文主要論述日本現代著名漢學家吉川幸次郎（1904-1980）有關《詩經》之研究方法。全文分為以下四節：一、吉川幸次郎生平概述。二、吉川幸次郎有關《詩經》之著作。三、吉川幸次郎之《詩經》研究方法。四、吉川幸次郎《詩經》研究方法之檢討。經由本文之分析，可知及川幸次郎研究《詩經》，以廣搜參考資料、校勘文本、依循舊注、分析語言等為其重要方法。此種方法乃沿襲清代之考證學風，並嘗受其師狩野直喜之影響。吉川幸次郎之《詩經》研究方法，使其所論客觀有據，並能重現《詩經》語言中所具之美感。然其解《詩》多依循舊注而少創新，又鮮少利用清代以後中、日學者之研究成果，故所解未免流於過度保守之弊。

This paper focuses on the works by Japanese Sinologist, Yoshikawa Kōjirō (1904-1980), and his research methodology on Shijing. It is divided into four sections: (1) the biography of Yoshikawa; (2) Yoshikawa's research works on Shijing; (3) Yoshikawa's research methodology on Shijing; (4) the discussions on Yoshikawa's research methodology. By way of this investigation, we find that Yoshikawa's research methodology on Shijing is primarily based on his exhausitve research on reference materials, texts collation, adhering to old annotations, anlayzing of linguistic elements, and other important methods. His methods of research is deemed as following the tradition of textual criticism of the Qing scholars, and is also heavily influenced by his teacher, Kino Naoki. Yoshikawa's research on Shijing is an objective study, which in particular, focuses strongly on the linguistic beauty of Shijing. However, his interpretations of Shijing sometimes lack innovative insights due to his close reading of old annotations. In addition, he seldom refers to studies made by the Chinese and Japanese scholars after the Qing dynasty, which nevertheless is a bit too conservative in his ways of interpretations.
