本研究依循空間與社會互構的觀點，闡述淡水捷運站公共空間為街舞青少年族群挪用時，所產生的社會排除與協商議題。藉由梳理青少年再造的街舞空間，剖析「成人化的」街舞空間如何被使用者改造，達到喚醒社會重視青少年空間使用與資源分配的目的。本研究使用之研究方法包括觀察法、問卷調查法與深入訪談法。研究參與對象則包含使用淡水捷運站公共空間的行人、街舞青少年、捷運站管理者等。希望了解因為身分、年齡、性別等社會差異，所產生自我與他人的認同與排斥機制。本研究發現可包含以下三點。第一，在各族群對應之下青少年也可能成為社會資源優勢者排除他人的使用權。第二，但可藉由理性行為建立妥善協商機制。第三，排除與協商可藉由解讀立場改變，使公共空間的利他行為更加顯著。社會排除具有多重網絡及轉化的特點，而公共決策機制應賦予青少年表達使用空間需求的管道，避免青少年的公共訴求遭到忽略，並重視多元需求與個體差異，公共空間的公共性才得以提升。
This study adopts the perspective of the mutual construction of space and society. It explores the issues of social exclusion and negotiation in the public space at Tamsui MRT station. Specifically, this research aims to understand the ways in which young people produce and transform the public space into a street dance location. We explore how the 'adultized' public space is reproduced by young street dancers. In doing this, this research emphasizes society needs to pay more attention to young people’s need of space. The methods adopted in the study are observation, questionnaire survey and in-depth interview. The participants include pedestrians, street dancing young people and MRT managers of the Tamsui MRT station. These methods are used to investigate the ways in which the social differences in social roles, age, and gender create the mechanism of inclusion and exclusion between the self and the other. There are three parts to this research finding. First, people with more social resources can exclude others’ usage rights, and therefore teenagers may be excluded. Second, more rational behavior can lead to a negotiable space. Third, if people try to understand others, public spaces would be friendlier. Soc ial exclusion has multiple networks that might be changed. The research findings suggest the publicity of public spaces can be improved if young people have opportunities to express their needs. Respecting the requirements and differences between users of public spaces is also needed.
