本論文以施叔青《行過洛津》一書為研究對象，探討空間與認同的關係。此書以描寫主人翁多次來台的過程，呈現出外來者對台灣這個島嶼自然與人文空間的觀察，並以台灣地理面貌的多變隱喻相關人物認同的變動，可說是身份疆界的文化地理學。本文試圖提出下面幾個問題：（一）以空間觀點來詮釋性別與土地認同可以得到哪些洞見？（二）本書作者如何將身體空間化、歷史時間空間化、以及不同人物所經歷的地理空間與人文空間，多層次空間形塑為台灣認同的想像。本論文指出此書主人翁許情的性別認同之建構與轉折過程，係以個別身體「之間」的相似或差異而成為當時的認同所在。除了不同身體之間，還有身體與衣服之間、同一個身體不同部位之間、身體與特定時刻所在空間位置之間、身體與戲劇角色之間等等多層次的「之間性」，在兩種狀態之間的穿梭、擺盪、游離、卡住、黏附，造成許情的反思與認同的進出。此書也以海洋、河流、高山、室內、室外不同空間「之間」的關係來作為台灣主體生成的隱喻。這本歷史素材的小說，將時間空間化，呈現身體在空間中的交會。

This paper attempts to explore the relation between space and the construction of identity, using the example of Passage to Lo-Jin, a historical novel written by Shih, Shu-Ching. Three issues would be raised and discussed in this paper. First, in what ways can the spatial approach and the theoretical perspective of locational feminism give us insights to understand the interaction of gender identity and local/national identity? I will explore the challenge given by this novel to the studies of contemporary Taiwan literature, pointing out the phenomenon that this novel is full of local knowledge about the historical town (Lo-Jin), and thus uses local history as a way to rethink well-established national history. The second issue of this paper deals with the writing techniques of spatialization, with regard to the ways natural geography and cultural geography intermingle to form metaphors of individual and collective identity construction.Overall, this novel express the diversity of cultural and ethnic groups in Taiwan, but the significant features are not about their similarities and differences, but about the space in between these differences which gives rise to self-reflection and the formation of subjectivity. The actual journey and symbolic journey in between different locations and social roles constitute the attraction of this novel.
