去年的中日台釣魚台爭議,肇因於日本的釣魚台「收歸國有」計畫,而在港台保釣人士的反對下,日本始終不肯放棄該計畫,終於引發中國內部民族主義浪朝,不僅向聯合國遞交直線基線聲明,並多次派出海監船、漁政船甚至軍艦於釣魚台海域巡航。而台灣政府認為釣魚台乃國際問題,且一再表明不可能與中國在該議題上聯手,似乎意味著我國的安全觀已逐漸產生變化。從歷史角度觀之,我國的安全觀係隨著兩岸關係的變化而轉變,從衝突對立、開放交流乃至於和平協議的倡議,每個時期的國家安全觀皆有所不同。而本文的目的即是透過兩岸關係的變化,以及台灣內外部的安全議題來探討台灣國家安全觀的轉變,藉以理解當前台灣的安全觀與未來發展。 The outbreak of Sino-Japan Taiwan Diaoyutai Islands Dispute in last year is mainly due to the former DPJ premier Noda Akihito declared the Diaoyutai Islands’ Nationalization Plan.
