In 2012, before coming into office, Tsai Ing-wen and the Democratic Progressive Party (DPP) used to boycott the import policy of U.S. beef under the Ma Ying-jeou administration. For some, the decision of President Tsai marks the shift of the policy stance of the DPP. This thesis aims to further examine this issue through the analysis of the external and internal conditions faced by the Tsai administration.According to the Two-Level-Games Theory of Robert Putnam (1988), when a government makes decisions on transnational policies, the decision-makers need to rationalize at two levels: the international level and the domestic level. This thesis seeks to answer: what international and domestic issues the Tsai Administration concerns about when making the decision on U.S. pork and beef import policy? And why Tsai Administration chose to announce the tricky policy at the end of August in 2020?The finding of this thesis is that at the international level, the trilateral relationship between Taiwan, the U.S., and Mainland China in 2016 through 2020 provided the Tsai Administration an ideal timing for rolling out the U.S. pork and beef importation policy. At the domestic level, the excellent anti-pandemic results in Taiwan that impressed the world during the Covid-19 pandemic ravaging the world in 2020 had encouraged Taiwanese people and boosted their support for the Taiwanese government. The combination of a window of opportunity at the international level and abundant political capital at the domestic level prompted the Tsai Administration to make the tough decision of import policy in August 2020.雙層賽局理論台美關係兩岸關係美豬美牛Covid-19Two-Level-Games TheoryUS-Taiwan RelationCross-Strait RelationUS Pork and Beef Importation PolicyCovid-19學術論文
