Since the 1990s, many countries have adopted various quota systems to promote higher levels of women’s political representation. International research confirm that such quota systems have had a positive impact on increasing women’s political participation. In Taiwan, studies on women’s political participation also shown that reserved seats for women have significantly boosted their involvement in politics. However, few existing studies have specifically focused on the political participation of indigenous women. The election results from 2002 to 2018 indicate a growing number of indigenous women running for and being elected to office. But what factors explain this increase in political participation? Is it the reserved seats for women system, political dynamics, or the background characteristics of the candidates that play the key role in encouraging indigenous women's involvement in politics? This paper analyzes data from local councilor elections between 2002 and 2018 and finds that most female candidates have prior experience in community involvement or political-related activities. Additionally, KMT nomination or recommendation, as well as incumbent status, significantly contribute to the election chances and vote share of indigenous female candidates. This paper analyzes the data of local councilor elections from 2002 to 2018, and finds that most of the female candidates have experience in community involvement or political-related experiences. KMT nomination or recommendation, as well as incumbent status, contribute to the election chances and vote share of indigenous female candidates, which aligns with existing research on women councilors at the national and municipal levels. The impact of the reserved seats for women system is reflected in its role in motivating participation. In line with previous findings on ethnic voting patterns, a candidate’s ethnicity is also significantly associated with their election chances and vote share, with Amis, Paiwan, and Atayal ethnic background positively influencing electoral performance. Lastly, female characteristics and breaking gender stereotypes through effective political performance help improve the election outcomes for indigenous female candidates.
