無數後現代手法演化的背後，臺灣當代小說家駱以軍無疑在小說中發出了一次又一次對於身份認同的內在追索：「我是誰？」的詰問。在身份認同的背後，是臺灣外省族群面對「歷史意識」和「本土意識」的召喚，糾葛於「中國大陸移民」或「臺灣外省人」的複雜心境。通過駱以軍的小說，我們利用文學倫理學批評的角度，更加清晰地看見臺灣外省人及其後代微妙的倫理兩難和認同矛盾。這是一層雙向而難解的倫理關係，中國與臺灣就好比父親與兒子的歷史對位，而駱以軍又是以怎樣的角度來勘測臺灣外省人及其後代在歷史光譜上的位置呢？在這個前提下，本篇論文正好借住中國學者聶珍釗所提出的文學倫理學批評，追問與思考他們所面對倫理問題的複雜性。

Behind numbers of post-modernist expressions, post-modem Taiwanese novelist Luo Yijun, undoubtedly had searched for identity recognition over and over again within his novels; ＂Who am I?＂ he questioned. Behind the identity recognition, it is when Taiwanese-Mainlanders face historical consciousness and local consciousness, they struggling between compIex mental state of ＂Chinese immigrants＂ or ＂outside of Taiwan＂ Through novels of Luo Yijun, we use the ethical literary criticism, which more clearly to see the subtle ethical dilemma and recognition ambivalence of the Taiwanese Mainlanders and their descendants. This is bidirectional and complicated ethical relations, which the relation between China and Taiwan just like relation between father and son relatively in history. But which point Luo Yijun had used to observe Taiwanese Mainlanders and their descendants ' position in historical spectrum? In this premise, this thesis borrows ethical literary criticism, to find out and think the complexity of the ethical problem they face.
