「平地居民權益促進會」(簡稱平權會)由臺灣山地鄉內的非原住民所組成，以「全面開放原住民保留地自由買賣」為主要訴求，利用政治與經濟優勢，力阻臺灣原住民的還我土地運動。 本文依據田野調查訪問及文獻分析，試圖從臺灣原住民保留地發展的歷史脈絡中，尋繹出平權會崛起之成因、組織過程、論述基礎、動員策略及背後的政治經濟權力結構。研究發現，平權會由南投縣仁愛鄉的旅館業者首發其軔，初期為地區性的壓力團體。爾後，臺中縣平權會成立，會長吳天祐利用既有的組織資源，加上其個人的政黨及財團背景，一方面鞏固平權會在山地鄉內的勢立，另一方面輔助其他地區成立分會，擴大為全省性的壓力團體。經由組織化的力量，進行政治動員，迫使政府開放原住民保留地自由買賣，以達成原住民土地的資本主義化。

　　　　　Pingquanhui (the association the promotion of rights of the Han people living in mountain district) was organized by non-aboriginals who live in aboriginal districts in Taiwan. This organization's main demand is "Authorize the market sale of all aboriginal reserve land". It is using its political and economic advantages to bring a halt to the "Return Aboriginal Land to Aborigines" movement. This paper analyses data from field research and existing documents. It attmepts to uncover why and how Pingquanhui organized, its discoursive and mobilizational strategies, and the political-economic power structure lies behind it. The research found that Pingquanhui was initially founded by some motel business owners in Jen-Ai District of Nantou County, and operated as a local pressure group. Later, a Pingquanhui's branch was opened in Taichung County. Taichung Pingquanhui President Wu Tien-yo used the organization's existing resources, as well as his own party-political and conglomerate background, to strengthen Pingquanhui's local force; furthermore he urged the establishement of new Pingquanhui's branches in other aboriginal districts. Pingquanhui thus expanded into a national-level pressure group, which is trying to use its organizational power and political mobilization to force the government to legalize the free-market sales of aboriginal reserve land, in order to achieve the capitalismization of all aboriginal land.
