回到經濟作為「家園維護」的本質，本文嘗試：1、指出台灣的發展歷程中，延續殖民敘事、邊緣化原住民族土地經驗的影響；2、以泰雅族傳統農耕為例，重新理解原住民土地知識與家園生計的意義；3、說明這些知識對當代台灣社會的啟發。本文強調：對於原住民家園生計的思辯，不是鄉愁式的懷想，而是在過去與現在的延續中，看到未來的可能。

Revealing the essence of economy as “the maintenance of home”, this paper:1) point out the influence of colonial narrative that marginalizes the indigenous experiences of land; 2) take the Tayal traditional agriculture as an example, and explore the ecological meaning of Tayal livelihood practices; 3) Address the inspiration it bring to contemporary Taiwan society. In conclusion, this paper emphasizes such a reflection in not out of nostalgia. Instead of that, the reflection is a seeking of future possibility from the articulation of present and past.
