成立、有效、生效是法律行为效力层次的三个方面,不同的层面对当事人有不同的约束力,其中成立是法律关系产生的起点,生效是法律关系现实运作的开始,有效则是沟通成立与生效的桥梁。三者的关系可以用一条线段来表示:线段的两端分别是成立、生效,线段两端点之间的持续过程便是有效。 The establishment, effective and effective are the three aspects of the validity of the legal act. Different levels have different binding force on the parties, of which the establishment is the starting point of the legal relationship, the effective is the beginning of the actual operation of the legal relationship, the effective is the establishment of the communication Effective bridge. The relationship between the three can be expressed by a line segment: the two ends of the line segment are established, effective, the continuous process between the two ends of the line is effective.
