台灣原住民族新認定的第15-16 兩族，是拉阿魯哇族（Hla’alua）及卡那卡那富 族（Kanakanavu）。這兩族從1954 年內政部公布原住民族九族以來，一直歸類在 鄒族。鄒族，習慣分南北鄒族兩部分。北鄒族指阿里山鄒族，南鄒族即指第15-16 兩族。兩族能得到認證的理由，應該是具備客觀及主觀的各種條件。本文指出衡量 民族認定的條件，有5 種客觀條件：一分類體系、二大社體制、三氏族聯繫、四宗 教觀與祭儀、五語言溝通，以及2 種主觀條件：一民族認知與意識、二了解三族的 對本案的意見與態度。依據這樣的條件來衡量第15-16 兩族想從鄒族分立出來，各 自成立一族的訴求，是可以成立的。

The newly recognized 15th and 16th aboriginal peoples in Taiwan are Hla'alua and Kanakanavu. The two peoples has been classified as Cou people since Ministry of the Interior announced that there are nine aboriginal peoples in Taiwan in 1954. Cou are used to be divided into two parts: northern Cou and southern Cou. Northern Cou refers to Alishan Cou and southern Cou refers to both the 15th and 16th aboriginal peoples. The reasons of the certification of these two peoples should be with objective and subjective criteria. This article points out there are five objective criteria to make ethnic certification: (1) classification system, (2) social system of Hosa, (3) relationship of clans, (4) religious concepts and rituals, (5) mutual intelligibility in languages, as well as two subjective criteria: (1) ethnic cognition and consciousness, and (2) the opinions and attitudes among the three peoples to this application case. Based on the objective and subjective criteria mentioned above, it is proved that the 15th and 16th aboriginal peoples’ appeals to separate from Cou and to be certified as two independent peoples can be accepted.
