日本の新防衛計画大綱下における日中間の安全保障関係のゆくえ

日本新防衛計畫大綱下日、中安全關係走向（The Future of Japan-China Security Relations under Japan's New National Defense Program Guidelines）

2009年9月，日本民主黨取代自民黨執政，在外交與安保上展現與自民黨政權的不同思考，力圖強化日中關係平衡美日關係，實現對等的「美日同盟」。然而，外交的理想不敵現實的安全利益外交、安保政策異於經濟、社會等內政相關政策，較不受國內政治影響，不論保守派或改革派當政，皆無法改變一國所處的客觀安全環境，全憑執政者的主觀好惡將政策改弦更張。在後鳩山內閣時期的民主黨政權揚棄「新自由主義」（neoliberalism）的外交路線，重回「攻勢現實主義」（offensive realism）的思維，建構新的外交與安保政策。本文將分析日本民主黨關於『防衛計畫大綱』修訂之討論，據以評估日、中的新安全關係走向。

On September 2009, the Democratic Party of Japan (DPJ) replaced the Liberal Democratic Party (LDP) and became the ruling party. DPJ has shown different diplomatic and security ideals from those of LDP, endeavoring to strengthen Japan-China relations to balance U.S-Japan relations and pursue an 'equal U.S.-Japan alliance.' However, these diplomatic ideals have been defeated by real security interests. Security and defense policies are different from economic, social, and internal policies in that they are not as easily influenced by the domestic politics. A country's objective security environment cannot be changed at a leader's will, regardless of the leader's position as a conservative or radical politician. In the Post-Hatoyama era, DPJ has abandoned the neo-liberalist diplomacy route and returned to the offensive realism ideals to construct the new diplomatic and defense and security policies. This paper is aimed at analyzing DPJ's amendments to the National Defense Program Guidelines and exploring the future of Japan-China security relations.
