本文以臺灣亂彈戲《大刀記》劇本為論述起點，進行相關文本的比較分析，試著從探尋各文本各自的「信息框架」內部訊息，並比較彼此間可能的呼應關係，以及不同「信息框架」訊息歧異處的意義，藉以了解文本流播過程中的互文性質變之辨證關係。論述以「信息結構」概念為分析前提，探討亂彈戲《大刀記》與同名之明傳奇《大刀記》及其相關史傳記載，以及臺灣中部流傳之「劉挺征大肚番」等傳說之間的關連。鑒於《大刀記》相關文本中，主要人物與其相關事蹟（情節）共構的「信息框架」結構體，有多重的呼應關係，進而推論：亂彈戲《大刀記》的主要信息框架，可能源自明傳奇《大刀記》及其相關史傳，另接收了民間傳說「劉挺戰大肚番」的部分信息，以傳統戲曲慣用的組織邏輯，進行了文本之重組，逐步確立當今可見之亂彈戲《大刀記》。

This study uses the storyline of Dadau Legend, a Luantan opera, as the starting point of discourse, and performs comparative analysis with related texts. We attempt to investigate all different versions of the text, and discover resonances between their “information structures”, as well the significance behind each discrepancy. In this way, we aim to understand the dialectical relationship of intertextual transubstantiation that occurs in the process of text circulation. The discourse uses an information structure approach as the analytical premise. It investigates the linkage between the Luantan opera named “Dadau Legend” and a legend from Ming dynasty with the same title, as well as many related historical records, including a folktale circulating in central Taiwan titled “Liu Ding battles with Dadu Tribe”. Since the “information frame” structure formed by main characters and major events (plots) possesses multiple corresponding relationships between all of the related texts for Dadau Legend, we infer that the main information framework for the Luantan opera “Dadau Legend” is based on the Ming dynasty legend “Dadau Legend” and other related historical records. The Luantan opera also takes some information from the folktale “Liu Ding battles with Dadu Tribe”. We also infer the text was restructured via typical organizational logic of traditional performances, leading to the gradual establishment of the current version of the Luantan opera “Dadau Legend”.
