Social identity theory indicates that people compare the in-groups to which they belong with out-groups, and develop negative feelings toward out-groups. According to the intergroup contact theory, contact between members of different groups can work to reduce prejudice, intergroup conflict, and improve social relations. ECFA, the most significant trade achievement between Taiwan and China, is predicted to reduce Taiwanese identity under the theory. For exploring this relationship, I compare identity data before and after the ECFA was implemented, and also discuss the Sunflower Movement and the new political word “Tian Ran Du.” I lastly compare the results of the Taiwan’s Presidential elections in 2008, 2012, and 2016. My research found that ECFA has not reduced Taiwanese identity obviously.en-USAll Rights Reserved.ChinaECFAIntergroup Contact TheoryNational Identity ConflictSocial Identity TheoryTaiwanElectronic Thesis or Dissertation
