過去台灣的選舉研究大多把台東視為國民黨穩定支持區，因此台東選民的投票意向也一直未受到政治學界的重視。然而台東不但在地理位置屬於邊陲，族群文化相當多元，人口外流，社會成型較晚，人民的教育水準即所得偏低，產業結構分工不健全，整體產值較少，進而影響地方政府資本累積的規模。本文嘗試就台東縣選民結構特質，已近十年縣級以上選舉結果為分析主軸，為台東縣是否已出現地區性政黨版圖提供初步討論，作為理解邊陲社會及多元政治文化的開始。

There have been lots articles with regard to Taitung’s electorates as the supporters of Pan-Blue camp. Indeed, it is according to the results from national to local elections in recent years. Taitung is described as peripheral county with lower income level, under average level of educational background, with agriculture-oriented economy and with multiple ethnicities. It is rarely happened for party alternation. These factors always confuse the real phenomenon when most western counties are regarded as the supporters of Pan-Green camp under the same conditions. Taitung county could be divided into three part according to the population: Han dominant area (Taitung city, Lu Ye, Kwan Shan, Chi Shang, Tai Ma Li, Green Island, Bei Nan), aborigines dominant area (Yien Ping, Hai Dwan, Ching Fong, Da Zan, Orchid Island) and ethinic balanced area (dong He, Chang Bin, Da Wu, and Cheng Kong). Generally speaking, Hakka and Holo support the DDP, whose supporters have stronger party identification. Aborigines and Taiwanese Mainlanders support Pan-Blue camp, no matter who candidates are. Each ethnicity has its own space frontier that decides the party domain and local characters. This paper would supplement the relevant studies and be the first discussion about peripheral politics.
