本研究運用「臺灣原住民社會變遷與政策評估」調查資料，分析都市原住民在代間社會流動的表現。研究發現如下：（1）相對於原鄉原住民，都市原住民有較佳的社會位置，且二代都原較一代都原有較佳的社會位置，此係受益於個人與親代的移徙；（2）在代間社會流動上，一代都原代間垂直流動傾向高於二代，一代較二代更能藉由遷徙改變先天的階層地位，且一代都原較易向上流動，顯示一代都原較能體現遷徙能動性；（3）教育對促進代間向上流動的作用，在年長世代的效用大於年輕世代，此與臺灣教育政策及原住民教育分流有關。未來建議可針對往返於都會與原鄉間的流徙原住民進行更深入的討論。

This research applies the Taiwanese Indigenous Survey data to compare the inter generation social mobility trend of the urban aborigine. The main findings are as follows: (1) the social economic statue of urban indigenous is better than people who still stayed in tribes, moreover, the second generation is better than the first migrant one. It might be benefit from the migration of their parents or themselves. (2) The trend of vertical mobility is more prevalent among the first generation than among the second one, in addition, the probability of upward mobility is also higher among the first generation than the second one. This finding implies that the first generation experience profounder mobility than the second one. (3) Education could improve the possibility of upward mobility; however, the positive effect of education is more significant among the oldest cohort than the younger ones. It might result from the changing education policy and the historical educational tracking. Based on above findings, the further research could focus on those migrants who move back and forth between the tribes and metropolis.
