消費地下空間：以臺北車站特定專用區之地下街為例

Abstract

都市的空間發展，涵蓋向外、向上和向下三個面向。然而相較於前兩者，後者卻是過去都市地理學的相關研究較少著墨的面向。有鑑於此，本研究將在臺北市的都市發展脈絡下，以同位於臺北車站特定專用區的地下街為例，探討都市的向下擴張。研究發現，交通動線的重構與新式交通運輸的拓展，即自1980年代開始的鐵路地下化工程和捷運路網的陸續興建，是資本主義城市將地下空間納入都市體系，相當重要的關鍵。然而交通動線的地下化只是資本主義城市收編地下空間的第一步，市政單位進一步依據相關規定，將地下空間打造成為兼具人員流動與商業活動的地下街，並藉由擬定的招商策略，形塑地下街的消費空間。換言之，本區的地下街，其空間的治理，高度掌握在市政單位之手。但是，在某一類型的使用者，也就是青少年的加入之後，改變了地下街部分空間的使用，其主要將地下街的廣場、通道挪作社團活動練習之用，如練習街舞；而青少年挪用空間的邏輯主要為硬體環境、區位等因素，展現了某種程度的抵抗。

Urbanization has been forcing cities to expand outward, upward and downward. Given that the downward developments of cities receive less attention in urban studies compared to the first two, this thesis focuses on the downward expansions of cities in the case of underground shopping malls in Taipei Main Station Special District. First, I will explain why and how making public transportation systems under the ground such as the railway and metro systems since 1980s in Taipei City is vital for the capitalist city to incorporate underground space. Second, how to transform underground space into underground shopping malls as underpasses and consumption space will be analyzed. It indicates that the governance of the underground shopping malls in the District is highly controlled by Taipei City Government. However, the uses of the underground shopping malls have been partly changed because teenagers have appropriated them for extracurricular activities such as practicing street dances. Consequently, the last part will address the appropriation of space by the teenagers.
