摘要：隨著現代戰爭對空間依賴性的增強,外層空間對人類的未來具有重大的價值，各大國為爭霸世界，正在太空展開激烈的軍備競賽。為限制外層空間軍事化，國際上出臺了相應的空間法律、法規來約束、限制這種行為，各主要外層空間條約均規定了探索利用外空的“和平目的”原則，但由于國際空間法本身存在一定缺陷以及其他國家對國際空間法有不同態度，這種約束力表現得明顯不足。本文通過對國際空間法的研究，指出了國際空間法存在的問題，分析了在國際空間法有限的制約范圍內外層空間軍事競賽的發展趨勢。筆者認為：限制外空軍事化和外空軍備競賽，完善現有國際空間法，修訂順應時代需要的空間法已是大勢所趨。

Abstract：With the reinforcement of depending on space in modern wars，the outer space has vast value on the development of the human being’s future, the superpowers are carrying on fierce military contest in the outer space in order to dominate the world．To limit militarization in outer space，some International Space Laws have been enacted corresponding1y，most Outer space treaties provide the principle of“peaceful purpose”during the exploration and use of outer space．But because these International Space Laws have some limitation and different country has different attitude to these 1aws，the sanction of these laws is evidently poor．This thesis by researching on International Space Laws，the paper points out the problems of International Space Laws，analyses the developing trend of space military contest in the restricted range of International Space Laws，and educes that to limit militarization and arms race in outer space，it’s a trend to perfect the existing International Space I was and constitute new ones what the time needs．
