当下习惯法的自然存在与习惯法概念多种定义的实际,是一种值得关注的现象。习惯法概念的定义有国家认可论、社会规范论、本土资源论和裁判规则论等,其立论支撑分别是民族国家的建立及国家制度一元理论、社会发展不平衡下的实际及社会规范多元理论、民族国家意识和地方性知识理论、社会纠纷解决的替代性纠纷解决制度理论,均有其合理、进步之处及不足。检视习惯法概念定义的变迁过程,为学界提供了一种动态的学术研究视角。 The current reality of customary law and the multiple definitions of the concept of customary law are a phenomenon of concern. The definition of the concept of customary law includes the theory of national acceptance, social norms, indigenous resources and referee rules. The theoretical support is the establishment of nation-state and the unification of state system, the reality of social development and the pluralism of social norms , The theory of nation-state consciousness and local knowledge, and the alternative dispute resolution system for the settlement of social disputes all have their rationality, progress and insufficiency. Examining the changing process of the definition of the concept of customary law provides the academic community with a dynamic perspective of academic research.
