本文藉由新高郡的案例，探討日本時代的集團移住政策如何衝擊原住 民部落的社會網絡。新高郡蕃地的原住民包括布農族的卡社群、丹社群、巒 社群、郡社群以及鄒族的鹿株群。1923年起，臺灣總督府開始在本區推行集 團移住。不過，此一時期的集團移住只是將部落就近移往地勢較低平處，整 體而言對原住民部落的社會網絡影響不大。爆發於1930年底的霧社事件促使 臺灣總督府擴大集團移住的規模。1933–1940年，本區大部分原住民部落遭 到遷移，導致丹社群、巒社群的社會網絡遭到裂解，且許多原本沒有社會關 係的部落被湊合在一起。這些證據顯示，集團移住確實產生分化原住民的作 用。

This research investigates how collective relocation policy under Japanese rule impact the social networks of indigenous tribes based on the case of Nitaka Gun. The indigenous people of this area include Takibakha Group, Takivatan Group, Takbanuaz Group, Isbukun Group of Bunun, and Luftu Group of Tsou. Since 1923, the Japanese ruler began to drive collective relocations in this area. Nevertheless, the relocations during this period just moved tribes to vicinity in flat locations thus brought little effect on the social networks. The Busha Incident occurred at the end of 1930 promoted the Japanese ruler to expand the scale of collective relocations. During 1933–1940, most indigenous tribes in this area were relocated thus the social networks of Takivatan Group and Takbanuaz Group was disintegrated, and many tribes without social relations were moved to rebuild new tribes together. These evidences show collective relocation policy indeed disunited the society of indigenous people.
