本篇論文以魏德聖的「海角七號」，「賽德克巴萊」二片以及其周邊產生的討論為文本，試圖整理未曾經歷日本統治過的台灣年輕世代對殖民記憶與國族認同的處理。論文第一部份著重電影文本及媒體討論中糾纏交錯不已的中國民族主義想像和日本殖民主義情懷。第二部分討論電影中角色經過努力後，受大時代翻弄而無法抵達預設目的之未果，未得交代的處境。本論文檢析魏德聖片中對於「殖民日本」的呈現，及探討來自邊緣性的解殖之可能性。

Drawing on Wei Te-sheng's Cape No. 7 (2008), Seediq Bale: Warrior of the Rainbow (2011) and the paratexts that bourgeoned around the films as my analytical text, this paper intends to study Taiwan's younger generation，s treatment of its colonial memories and national identification, despite having only second-hand experience with the past. The first part of the article discusses the intertwined and inseparable discourses of Chinese nationalism and Japanese colonialism. The second part accounts for the liminal, work-in-progress status the characters， development and actions seem to linger in, consciously or unconsciously reflecting the status of Taiwan，s (non) nationhood. This article examines the cinematic presentation of “Japan” and the possibility of commencing a process of self-decolonization from the margins.
