World trade has become increasingly regionalized in the past decade as a result of preferential arrangements. Due to Taiwan's unique international political status, its present government believes that closer economic integration with China would enhance Taiwan's economic prosperity and prevent Taiwan from being marginalized in East Asia. Taiwan hence signed the Economic Cooperation Framework Agreement (ECFA) with China in 2010. This paper summarizes arguments opposed to the ECFA from economic and political perspectives. Despite the fact that Taiwan is expected to reap greater benefits from deeper integration with China, simulation analyses show that the welfare-enhancing effect brought about by the ECFA is quite limited, because the ECFA contains no definite content or timeline other than an early harvest list.
