近年來，日本的防衛政策發生了許多重大的變化。如日本政府認可了「集團自衛權」的行使權、美日兩國修訂了新版的「美日防衛合作指針」以及日本國會通過了新的「安保法案」，這些變化勢必將帶給亞太地區不小的影響。在此之中，2013年，日本政府所制定的新「防衛計畫大綱」更顯示出了日本安全觀在面對快速變化的國際情勢之下，不停地求新求變以確保國家安全的意圖。 「防衛計畫大綱」是為日本防衛政策的最高指導方針，具有非常高的重要性。故本論文將以防衛計畫大綱作為基礎材料，對日本冷戰後的安全觀變遷進行研究。防衛計畫大綱至今(2016)共有五個版本，從第一版(1976年)到最新的第五版(2013)，橫跨了冷戰與後冷戰時代，其中各版的內容更是發生了許多變化。如冷戰時代，日本的主要威脅是來自於蘇聯的全面入侵。而到了後冷戰時代，防衛政策的重心則是開始創造能夠對應「複合事態」的新體制。 本論文將基於「新古典現實主義」與「歷史制度論」兩大理論的角度，對防衛計畫大綱展開分析。並特別著重於「政策的繼承性」、「國內政治勢力的演變」、「中日關係發展」以及「亞太地區安全形勢」等等議題。在探究日本安全觀變遷的同時，試圖理解日本防衛政策所具有的特殊性。 / Japan's defense policy changes significantly in recent years. New cabinet decision of the right of collective self-defense, new Guidelines for US-Japan Defense Cooperation and new national security bill. Definitely, those changes will impact Asia-Pacific Security. In those transitions, new Japanese National Defense Program Guideline(NDPG) will be a relevant reference to see why and how does Japanese security view get changed. This research will use NDPG as basic materials to find out the transition of Japan's security view in the Post-Cold War. NDPG has five editions for now. Form first edition(1976) to fifth edition(2013), NDPG can tell us what 's the difference of Japan 's security between Cold War and Post-Cold War. This research based on “Neoclassical Realism” and “Historical institutionalism” to analyze NDPG. Furthermore, we will concern of “Succession of policy”,” transition of domestic political power”,”China-Japan relations”and” Asia-Pacific Security”and so forth.

摘要 近十年來，北京已轉變它在東南亞區域的外交政策，希望與東盟成員國家能維持一定的良好關係，並發展出一個和平又互利的戰略夥伴關係。1997年到2012年之間，中國與東盟從建立對話機制開始，雙方實質上的經貿投資與聯合計畫都快速增長。從多方面顯示：不僅在政治、經濟與維持區域安全等方面，中國與東盟成員都已共享務實的合作成果，近來更大力拓展雙方的互連互通與交通基礎建設，期使共同邁向實質的中國－東盟戰略夥伴關係。 南中國海周邊各國的利害與衝突不一，是個複雜的區域；而中國與東盟成員之間的對話機制與合作關係的基礎上，有助於減緩此一緊張情勢。本報將採用文獻分析的定性研究方法告指出（實際上）（1）北京的東南亞外交政策正面臨的主要挑戰是有東盟以外國家新勢力的強力介入或是舊有勢力的急速恢復，進而互相抗衡。（2）中國被稱為有過分自信的政策規劃期間，北京在推動與東盟戰略夥伴關係，實際上中國與東盟成員關系都已共享務實的合作成果。 / Abstract China-ASEAN relations have been transformed over the last decade by Beijing’s aim to create a stable neighboring environment as outlined in its state policy of peaceful development. This relationship has been embodied in a series of joint plans and statements with ASEAN between 1997 and 2012. In the three areas of politics and security, economy, and connectivity and infrastructure, the paper will show the relationship has followed a similar pattern, that is cooperation has been deepened according to China’s aims for its relationship with Southeast Asia. While relations have continued to develop in these areas, constant focus on the issues of assertiveness and territorial disputes, particularly over the last 3 years, means that progress and development in the relationship often receives little attention. The South China Sea is a complex issue, however security-related dialogue between China and ASEAN member states will be shown to have mitigated this problem to a certain extent. The paper will show that the challenges to Beijing’s policy lies with countries from outside the sub-region and their return, or growing role in Southeast Asian affairs, and that in fact during the period when China has been labeled more ‘assertive’ its relationship with ASEAN has deepened and developed as planned. In its use of materials the paper will employ the qualitative research method of document analysis.
