摘要
中華人民共和國（中國）與北韓（朝鮮）在冷戰時期確立了兩國的軍事同盟關係。雙方在二次大戰期間合作抗日的情誼，以及國際共產運動中的意識形態連結，是中朝軍事同盟形成的最主要力量。然而自從蘇聯解體之後，共產與資本陣營的對立格局消失；中國與北韓的外交政策也不再需要考量陣營利益而得以將自身國家利益做為決策時的優先考量因素。中國在改革開放之後，不再對美國及南韓等國家採取對立的態度，而改行經貿合作，並且尋求一個穩定、和平的國際環境；這構成了中國在後冷戰時代的外交政策主軸。另外一方面，北韓長久以來奉金日成的「主體思想」為圭臬；在冷戰時代，主體思想受到國際共產運動的制約而有所妥協，如今主體思想的發揚不再受到任何拘束，進而成為主導北韓對外關係的重要力量。中國和平發展、經貿開放的路線，以及北韓追求獨立自主的主體思想，造成了兩國在具體外交行為上的矛盾與衝突，這尤其反映在中朝兩國對於兩韓軍事衝突以及北韓發展核武議題看法上的不一致。在北韓堅持不放棄核子武力，並且不時與南韓發生軍事衝突的狀況下，中國必須承受國際上要求約束北韓的壓力，而更為重要的是，這對脆弱且複雜的中美關係將產生巨大的衝擊，在國防上與經貿上皆對中國形成了嚴峻的考驗。而這種種事態的改變，也連帶使得中朝軍事同盟的緊密性產生變化。過去「鮮血凝成」的盟友關係，在冷戰結束之後似乎已不再顯得如此堅固。本研究之目的，即在於找出構建並維繫中朝軍事同盟的因素，以及破壞同盟穩固性的因素各為何。

The Sino-North Korea alliance was established in the cold war. The bonding forces of the alliance are the common experiences of anti-Japanese struggle during World War II, and the ideological bond of the international communism movements. However, since the disintegration of the Soviet Union, the international structure of bipolarity was eventually collapsed. Both Chinese and North Korean governments don’t have to obey the guidance of the Communist International anymore while making their policies. Instead, national interests have become the main considerations for decision-making of the Chinese and North Korean governments. After China adopted its economic reform programs, it changed its attitude toward America and South Korea from opposition to engagement, and began to intensify the economic and trade ties among them. China seeks a peaceful and stable international environment, which is the most beneficial to its development. Therefore, China tries to prevent any military conflicts from breaking out in the region. On the other hand, the state of North Korea is dictated by Kim Il-sung’s “Junche ideology,” which impulses North Korea to take a more aggressive posture toward America, Japan and South Korea. This kind of posture, however, is in contradiction to China’s peace-seeking strategy, and also affected this once solid alliance.
