It is believed that almost every Town's District Committee of Mediation in Taiwan is dominated by local factions and the committee members are the important figures within their factions. In this research, based on the assumption that the Committee members are convenient to access political, social and economic interests, we hypothesize that in Taipei County the more powerful a local political faction is; the more in-tervention it has toward the District Committee of Mediation. Therefore, we use 3 models to examine the relationship between lo-cal political factions and the District Committee of Mediation by statistic datum, such as the amounts of mediation cases, the successful rate of me-diation and soon. However, through depth interviews to 8 committee members and 3 clergies in different Towns of Taipei County which provides not only the quantitative explanations but the qualitative analysis for this research. The author expects that students of Taiwan's local political factions re-search will have mo0re refined models contributed by this paper to dupli-cate further studies.
