冷戰時期，台灣小說經常寫及外省人、本省人與美國人的跨國戀情，我認為這是對冷戰結構與分斷體制的回應，看似「談情說愛」的跨國羅曼史，實帶有國族寓言性質，指向「想像中國」的歷史危機。 為兼顧世界冷戰體制與台灣歷史進程，我以1947年冷戰元年暨台灣發生二二八事件，至1987年台灣解嚴為度，嘗試建立「中美婚戀小說譜系」，並藉此一視角，調校台灣學界指稱九O年代前，女作家鮮少介入國族論述的觀點。 我由「性別政治」、「交換經濟」、「歷史敘事」三大向度切入研究，正文共計三章： 第二章以不同「性別—國族」角色組合入手，探討國族欲望與異性戀父權婚姻制度的共謀。「美國男性—中國女性」婚戀敘事，隱現殖民型態的轉變：由五O、六O年代的政治殖民，演進為七O年代以降的新殖民主義與文化帝國主義；「美國女性—中國男性」婚戀敘事，則將國族論述中的去勢主體，轉化為兩性關係的陽剛主體，二者之敘事差異，揭示小說作者的認同疆界。從「孤女」到「失婚者」，見證國族父親的缺席，與再次缺席；而「跨國妓女」與「去勢男性」，則標記「國體」與「國魂」的糾纏。 第三章借助交換經濟理論，觸探主體的求存之道。其一為東方想像，旗袍的文化展演，織紉殖民現代性；其二為複寫生命治理技術的「綠卡婚姻」；其三為「漢學家」的戀情，透過「國故」，贖回「故國」。 第四章探析歷史敘事。當情愛話語被挪用為國族起源的證詞，除卻「選擇性記憶」，更包含「創造性遺忘」，以失憶作為最後手段。亦即，中美婚戀敘事實則是種透過「國體」，尋找「國魂」，發明記憶的工程。 / This study argues that the trans-national love and marriage among Mainlanders, Taiwanese and Americans in the Taiwanese novel during the Cold-War era is the response to the cold war structure and division system between Taiwan and China. Under the mask of love affair, the trans-national romance in those novels implies a national allegory of the historical crisis of the imagined Chineseness. Considering the Cold War system and the historical developments of Taiwan, this study constructs a genealogy of Chinese-American romance novel written during the period between 1947, the first year of the Cold War and the year of “The February 28 Incident”, and 1987, the end of “The Martial Law Era”. Also, through seeing the Chinese-American romance as a national allegory, this study intends to fix the commonly accepted point of view in Taiwan, that female writers barely participated in the construction of national discourses before 1990s. The Chinese-American romance novels were discussed from three perspectives：Sexual politics, exchange economy and historical narrative. Chapter two focused on the differences of sex-nation combination in the novels, further discussing the complex relations between the desire of the nation and the heterosexual patriarchal marriage. The narrative of the romance between American males and Chinese females in those novels suggests that the form of colony was transformed from the political colonialism in the 1950s and 1960s to the Neo-colonialism and cultural imperialism after the 1970s. On the other hand, the narrative of the romance between American females and Chinese males transforms the castrated subject in national discourses into the masculine subject in sexual relationship, which allows us to see the barrier of the identity of the authors. The orphan girl and the divorced people witness the absence and re-absence of father nation. The trans-national prostitute and castrated male, on the other hand, marks the intertwined relationship between the “Nationalized Body” and “National Spirit”. Chapter three adopted exchange economy theory to inquire the strategies for living of the characters, who were viewed as a collective group that represent the nation, in the novels：（1）The eastern imagination created by cheongsam, demonstrate by the female characters to approach colonial modernity,（2）the Green-Card-Marriage disciplined by biopolitics, and（3）the romance that involves Sinologists, who seek to use their Sinological knowledge to redeem the perished China. Chapter four explored the historical narratives. Through revealing the national allegory in the narrative of Chinese-American romance, the narrative reflects both a construction and re-construction of understanding of the nation-state. In conclusion, the transnational romance is a way of finding and enacting the national spirit and identity.
