The purpose of this study was to analyze the percentage of votes Ko Wen-Je obtained. This study assumed that the votes Ko won were from Democratic Progressive Party (DPP) traditional stronghold and he newly obtained. 　　This study used spatial analysis and set 456 villages in Taipei City as analysis units, analyzing different aspects like population structure, socio-economic background, the relevant platform and spatial factors. Besides, through the traditional and spatial regression models, the election can be described more completely. The study found that Ko’s percentage of votes was deeply influenced by the DPP’s.
