本論文研究與分析的對象是兩位客家作家，亦即吳濁流與王幼華，嘗試解釋多重認同概念與這兩位作家的關聯，進而再把視野延伸至台灣新文學的發展過程中。 本文的第一章先是由客委會推廣「多重認同」的概念談起，第二章則試著為多重認同的理論意涵進行釐清。於本文的第三章當中，本研究已然指出，《亞細亞的孤兒》裡面已經蘊含了多重認同的想法，而在本文的第四章裡面，吳濁流更提出了類似民主化的論點，期望不同的族群可以藉由認同台灣來解決認同歧異性的問題。就本文的第五章來說，解嚴後崛起的小說家王幼華，其實已經表明自身早已具備了多重認同的思維。而在第六章裡面，王氏的重要長篇小說《廣澤地》與《土地與靈魂》，都可說是一種多重認同概念的體現。循此，從吳濁流到王幼華，這兩位橫跨近百年台灣新文學發展史的客家作家，各自以不同的方式與多重認同的觀念產生了關聯。 多重認同的概念，不論是吳濁流抑或是王幼華，都是他們的身分認同的真實處境。對吳濁流來說，族群認同的問題，不應該構成國家認同的障礙，大家應該秉持民主的精神，共同為台灣的發展而努力，反過來說，不同族群之間的多重認同，應該也可以是促成台灣進一步民主深化的要素。就王幼華來說，由他對於多元文化發展的肯定就可以看出，倘若說多元文化會有助於台灣的民主深化，那麼，多重認同的概念也就會有助於民主化的進展。 / This thesis will investigate and analyze two Hakka writers: Zhuoliu Wu and Youhua Wang. This thesis will also try to explain these two writers’ texts from the viewpoint of multiple identity, and then locate this concept of multiple identity in the development of Taiwan new-vernacular literature. Chapter One discusses the concept of multiple identity spread by Council for Hakka Affairs, and Chapter Two tries to define clearly the theoretical meaning of this concept. Chapter Three suggests that the idea of multiple identity is already embedded in Orphan of Asia. In Chapter Four, Wu brings up an idea similar to the concept of democratization with the expectation that different ethnic groups can resolve the problem of diverse identities by identifying themselves with Taiwan. In Chapter Five, Wang, a writer of the generation after ended martial law, tells us that he has possessed the idea of multiple identity. And in Chapter Six, two important novels, Swampy ground and Land and Soul, represent the concept of multiple identity. Accordingly, Wu and Wang relate the concept of multiple identity in his own way, and the writing course of these two Hakka writers almost stretches over the development of Taiwan new-vernacular literature. For both Wu and Wang, the concept of multiple identity could be viewed as their true situation. For Wu, the problem of ethnic identity should not be an obstacle of national identity, and everyone should try hard to develop Taiwan. In other words, multiple identities among different ethnic groups will contribute the further consolidation of Taiwan’s democratization. For Wang, according to his confirmation of multiculturalism, we can understand that if multiculturalism has a contribution to the consolidation of Taiwan’s democratization, the concept of multiple identity will be conducive to Taiwan’s democratization.
