美國如何操作外交政策訊號而使其政策意圖能夠被正確解讀呢?過去研究探討美國外交政策是否因「聽眾成本」大小而變得可信。但對於美國政府如何操作外交政策訊號卻未有系統性研究。本文介紹過去學界引用賽局理論所推演出的兩項假設。即在高賭注系列事件上，美國外交政策訊號呈現正反夾雜，混淆不一的現象。而在低賭注系列事件，美國政策訊號則呈現重複敘述，單調一致的現象。本文以美國在南海島礁爭議，以及其在 APEC 承諾的系列事件為例，試圖檢證上述兩項假設。本文發現就此兩系列案例，美國..

How does the U.S. manage its foreign policy signals to ensure its intentions are read correctly? Scholars have invoked the concept of ‘audience cost’ to explain credibility of leaders’ threats and policy signals.

2011 年 5 月 2 日美國特種部隊攻擊賓拉登(Osama bin Laden)之住處並且結束長達十年對於頭號國際恐怖分子的追擊，在此之後，各國對於此事件的反應呈現出不同的面貌。本文將以實證方法研究美國與各國的外交關係、各國對賓拉登事件的反應、主要媒體評論之間的互動關連，整理出支持與不支持美國的總表。本研究亦將思考:在採取爭議性的方法達成其國家利益的同時，美國霸權是否可以在未來持盈保泰?本研究所採取的新聞分析方法，是否能夠提供外交政策研究更多的可能性? ..

As the U.S. special forces thundered into Bin Laden’s compound and terminated the decade long chase of the most wanted terrorist on May 2, 2011, the global reaction to this incident presented diverse versions for interpretation. This empirical study answers the questions: can the U.S. identify those who support or oppose its foreign policy by their reactions to the Bin Laden incident? By probing into the governmental archives and major media in selected countries, this research answers two more important questions: has ..
