本文探討臺東市馬社阿美族社會組織運作基地「集會所」，在區位和功能上，隨著臺東平原的社會環境變遷，而轉變的過程。 1887年馬社遷建現址，於六個部落出入口和部落中心共建有七個「集會所」，以防禦呂家社卑南族的侵擾。 日治時代，日本警察制度完全取代臺東平原部落防衛系統，故馬蘭社集會所因人口減少而兩度縮編，最後剩下位於部落而中心的總集會所。 戰後臺東都市發展，漢人不斷遷入，1961年之前集會所全被變賣，該年另由鎮公所興建活動中心；2004年馬蘭社開始重建集會所，也因都市地價上漲、落部漢人人口佔優勢，而不得不「原地重建」。

This paper aims to investigate how social changes in the Taitung plain have affected the location and function of the Malan Amis’ Men’s Houses. In 1887, the Malan Amis moved to their present location and established their defense system against the Lika tribe (Puyuma), which was the strongest tribe in the Taitung plain. Thus, seven Men’s Houses were established; one in the center of the tribe was the major Men’s House and six branches were located on the main entrances to the tribe. During the Japanese colonial period, the Japanese police system completely replaced the tribal defense system in the area. Moreover, because the population of the Malan. Amis had decreased, the number of Men’s Houses was reduced in 1919 and 1941. Finally, only the major Men’s House was retained. After World War II, following the urbanization of Taitung City and the growing number of Han immigrants, the seven Men’s Houses were all sold by 1961. In that year, the Taitung city government built a community center for the Malan tribe. Construction of a new Men’s House in the Malan Amis’s community was started in 2004. However, because the cost of land was high and the Han immigrates have become the major population in the community, the Malan Amis were force to rebuild their Men’s House at high original site.
