【摘要】 冷战结束后，东北亚地区安全环境发生很大变化，成为大国力量角逐、寻求新平衡的热点区域。现今的东北亚是世界大国战略利益的交汇区，这里汇集了中国、美国、日本、俄罗斯四大国的利益，同时也是韩国、朝鲜等中小国的利益交汇区。从地理上看，美国并不是一个东北亚国家,但它在东北亚地区存在巨大的利益。作为惟一的超级大国,美国介入了几乎所有重要的东北亚安全事务,并在其中扮演某种关键性的角色。本文以冷战后东北亚安全格局中的美国因素为主要研究对象,首先对冷战后东北亚地区的安全状况进行了分析，通过对东北亚安全格局形成的概述及冷战前后东北亚安全格局演变的对比，从而对东北亚地区安全现状获得更为全面的认识和了解；其次运用历史研究、比较研究等方法，分析了美国东北亚安全政策的演变，并具体分析了美国对东北亚国家的政策；再次，运用个案分析法结合地区安全热点问题进行案例分析，以朝核问题为例分析东北亚安全格局中的美国因素。最后得出结论，目前影响东北亚地区安全的各种因素中,美国是其中最关键的因素，其对东北亚地区事务的深度介入,已经严重干涉了区域内主权国家的内政,影响了区域内国家之间的正常关系,激化了本地区的焦点问题,对区域安全构成了严重的危害。准确分析美国因素在东北亚地区安全格局中的作用对于把握美国与东北亚各国的双边关系和今后走向，以及对东北亚多边安全机制的构建都大有裨益。更多还原
