二十一世紀後美國東亞軍力調整之研究

Abstract

本文以「新現實主義」(neorealism)，或被稱為「結構現實主義」(structural realism)做為研究途徑，從國際政治系統層次體系，探究美國在二十一世紀後，所進行的東亞軍力調整。本文首先檢視二十一世紀後東亞戰略環境，以及美國的兩位總統，小布希(George W. Bush)，以及歐巴馬(Barrack Obama)，的面對這樣的東亞安全環境，採取的戰略與政策儘管有不同，但同樣在軍事及外交上，強化與東亞國家之關係，藉以建構一個對美國有利的東亞安全環境，藉以面對來自崛起中國的挑戰。接著，本文將探究美國與中國之關係，藉以釐清美國在進行東亞軍力調整中，如何處理中國的因素後，探討美國在二十一世紀後，在東亞進行的軍力調整的原因、方針以及概況，以及美國的東亞盟邦在軍力調整後所扮演的角色，並探究美國在東亞軍力整編時所面對的困境與挑戰。\n\n本文發現，二十一世紀美國進行東亞軍力調整之時，也反應了其東亞外交與安全戰略，以及美國建構一個以「美日同盟」為主軸的安全戰略體系已經形成，並由美國的其他東亞盟邦輔助支援。然而，美國的東亞軍力調整，也面臨了許多困難與挑戰，包括美國東亞盟邦，甚至美國自身的問題等。\n\n最後，本文也建議未來可針對抑制中國軍事能力的戰略，以及台灣在美國東亞安全戰略可以扮演的角色進行研究。

The research approach used in this dissertation is neorealism (structural realism).

Meanwhile, an U.S. security strategy based on U.S.-Japan alliance has established, with the support from other U.S. allies and partners in East Asia. However, the U.S. indeed faces difficulties and challenges, including problems from its allies and even the U.S. itself.\n\nLastly, this dissertation suggest some research directions in the future, including a strategy which can suppress Chinese capabilities, and the role that Taiwan can play in the comprehensive U.S. East Asia security strategy.
