本文以2001年立委選舉資料探究台聯的選票分布情形,採用候選人在各村里的得票離散程度指標、累積部分村里得票數百分比、和跨年度得票率穩定程度三種衡量工具,研究結果證實台聯候選人的得票分布呈現極為明顯的集中情況,對特定候選人的個案研究也發現台聯候選人跨年度得票率的穩定度有相當的可觀性。本文更進一步說明台聯實際運作的邏輯乃基於現行立委選舉制度與其群眾基礎所產生的互動關係。
Is it the ideology affiliated with ex-president Lee Teng-hui or the traditional local political factions that consist of the bases of Taiwan Solidarity Union's support? Our study finds that the later plays more important role than the former does. The study derives three indicators using village vote counts from the 2001 and some from 1995 and 1998 legislative election records, the first. is a Gini-coefficient type indicator showing the extent of candidate's vote dispersion pattern; the second uses votes from only a portion of total villages, from top down 10%, 20% and from bottom up 10%, 20% to show the distribution of candidate's strength and weakness; the third uses the overlapping percentage of candidate's top 5% vote-getting villages during 1995, 1998 and 2001 elections to examine candidate's steady strength before and after the Lee Teng-hui affiliation. The article also discusses the campaign strategies employed by the TSU for maximizing her political strength under the SNTV electoral system in Taiwan.
