觀看「他者」一直是主流社會從事觀光活動時的一部份，而「他者」被視為找尋異族情趣中的差異性和興奮性的來源，然而原住民觀光的發展在主流社會觀光客夾帶大量豐沛的資源進入到部落的同時該如何處理與應對？本研究藉由觀光空間與活動符碼的解讀，展示司馬庫斯觀光發展過程中背後所欲呈現之企圖，以及在面對任何可能性的同時如何堅持自己的主張並實踐自身存在的真實性之追求。研究自2006年1月至2009年6月底以民族誌方式進行資料蒐集。得以下結論：司馬庫斯在觀光發展過程中，活動型態與空間型態上的轉變以部落自決為本，來達成存在性真實的實踐與主體性的表達，並拓及未來發展的可能性。研究結果對於台灣原住民部落觀光發展上真實性與自主性有更深一層之理解，研究建議存在性真實之概念可運用於未來相關研究與觀光規劃之中。

In many senses, viewing the ‘other’ has always been a part of the tourist activity of dominant society. The ‘other’ has been seen as a source of potential exotic pleasure brought about by differences and excitement. However, how the indigenous village handles the touristic matters when the ubiquitous tourists pour into the village? This study examines the issue of authenticity in touristic space and activity, how Smangus Village pursuing the concept of existential authenticity through its tourism development and tourism activity. The field survey started in January, 2006 and ended in June, 2009. The data were collected through ethnographic methods. This study shows that Smangus are entitled to evolve in response to change circumstances (space and activity) in their own way, instead of as others expect — claiming and exercising that freedom is the ultimate expression of existential authenticity. The research results will enhance the understanding of autonomy and authenticity matters of the aboriginal villages in Taiwan and suggests how existential authenticity concept can be used in the future research and in tourism planning
