民事主体制度是民法的重要制度之一,是民法其他制度全面展开的前提和基础。其历史发展经历了一个由单纯的自然人到自然人和法人的二元主体再到主体多元化的演变过程,呈现由“人可非人”到“非人可人”的趋势。但是,开放型的多元民事主体制度并非毫无瑕疵。构建民事主体制度时必须注意民法的市民法本质,不能违反人文主义的精神。 The civil subject system is one of the important systems of civil law and the premise and foundation for the full implementation of other civil law systems. Its historical development has undergone a process of evolution from a purely natural person to a dual subject of natural and legal persons to the diversification of the subject, presenting a tendency of changing from “human to nonhuman” to “nonhuman”. However, the open, pluralistic civil subject system is not without flaw. When constructing civil subject system, we must pay attention to the essence of civil law of civil law and can not violate the spirit of humanism.
