Research on Collective Identity Formation in the Japan-U.S.Alliance in the Post-Cold War Period

1.美日同盟集体认同的形成是日本安全政策近期转变的一个重要因素，尤其是后冷战时期日本自卫队（SDF）海外派遣的增加。集体认同的概念定义：在非暴力和互助的基础上与其他国家建立相互信任的认同。（美日安全共同体的基础）操作性：我分析了集体认同的行为和态度成分。此外，我试图追踪日本决策者对日本描述的时间顺序变化。资料：联合公报、联合声明、联合声明、日本防卫白皮书等公开文件。研究方法：公开文件内容分析，部分使用计算机程序。分析结果：行为因素：继续强调自由和民主的基本价值；扩大在外部威胁、战略目标、作用和使命等方面的共识。态度部分：加强在政策磋商、联合研究和费用分担方面的防务合作；日本的身份认同：由于冷战的结束和日本经济的停滞，日本作为西方成员和经济大国的认知下降；扩大自卫队的海外任务：这反映了美国对日本国际和平合作和后勤支持的长期期望

1.Main ArgumentCollective identity formation in the U.S.-Japan Alliance is an important factor of a recent transformation in Japan's security policy, especially the increasing overseas dispatch of the Self Defense Forces (SDF) in the post-Cold War Period.2.The Concept of Collective IdentityDefinition : identification with other states on the basis of mutual trust in terms of non-violence and mutual aid.(The foundation of the U.S-Japan security community)Operationalization : I analyze the behavioral and the attitudinal components of collective identity. In addition, I attempt to trace chronological change in the description of Japan by Japanese policymakers.Materials : public documents such as join communiques, joint declarations, joint statements and Japan's Defense White PapersResearch method : content analysis of public documents, partially by using a computer program.3.The Results of AnalysisBehavioral component : continuity of emphasis on the basic values of liberty and democracy; the expansion of the areas of consensus on external threats, strategic goals, and roles and missionsAttitudinal component: strengthening of defense cooperation in policy consultation, joint research, and cost sharing ; maintenance of the level of joint exercises, except for the Air Self-Defense Forces (ASDF)Japanese Identities : the decline of perception as a member of the West and an economic power, due to the end of the Cold War and the stagnation of Japanese economy ; the rise of perception as an ally of the United StatesExpansion of the overseas missions of the SDF : This reflects long-term expectations by the United States for Japan's international peace cooperation and logistics support
