先秦时期东亚核心地区国家之间的关系与现代国际关系有较大的相似性,因此,挖掘和梳理先秦时期东亚区域的国家间关系对于当今国际关系理论和实践具有重大意义。以巴里.布赞的单位和解释源为理论分析工具来阐述先秦时期东亚体系由“单极主导”体系向“多极”体系的演进过程,以期从中得出一些有益启示。 The relationship between the countries in the core areas of East Asia in the pre-Qin period has a great similarity with the modern international relations. Therefore, excavating and combing the relations among nations in East Asia during the pre-Qin period is of great significance to the theory and practice of international relations today. Based on the unit of Barry Bazin and the source of explanation, this paper expounds the evolution process of the East Asian system from “unipolar dominant ” system to “multipolar ” system during the pre-Qin period with a view to deriving some helpful revelations.
