《日美安全保障条约》从签订之日起就深刻影响着亚太地区的国际关系,之后在岸信介内阁、安倍晋三内阁时期被再次修改。本文通过考察日美安全条约的起草、制定和交涉过程,主要运用政治过程论分析日本国内各政治主体之间的利益调整。日本通过安全条约实现了日本与美国的高度捆绑,达到了长期保证日本政治、社会稳定的目的。但是,日美安全条约也带给日本许多负面影响。仔细剖析条约起源,有助于深入了解日美关系及日本国际政治的实际运行模式。 “Japan-US Security Treaty” has profoundly affected the international relations in the Asia-Pacific region since it was signed, and was subsequently revised again during the time of the Kishi Minato Cabinet and the Shinzo Abe Cabinet. By examining the process of drafting, formulating and negotiating the Japan-US security pacts, this paper mainly analyzes the adjustment of interests among various political subjects in Japan by using political process theory. Japan achieved a high degree of binding Japan and the United States through a security treaty and achieved the purpose of ensuring long-term political and social stability in Japan. However, Japan-US security pacts have also brought many negative effects to Japan. A careful analysis of the origins of the treaty will help us understand the actual pattern of Japan-US relations and Japan’s international politics.
