The problem of methods of literary studies is always paid less attentions by the scholars in Taiwan. However, modern literary studies had emerged as a prominently distinct field in literature by the 1990s. Owing to this impact from the Western academic circle, the modern literary studies had begun to stress on the research method. The research method of modern literature can not be only divided into the qualitative and quantitative inquiry, but also into four different levels by itself, that is , the methodology, approach, method, and technique.

This article attempts to offer a comprehensive study under the following three aspects: (1) the levels of research method; (2) the qualitative and quantitative inquiry; (3) the literary theory and study.
