行政行为本身并没有直接的效力,由于行政权可以认为是国家政权的组成部分,因而基于行政权而发生的行政行为就具有了国家的公信力和执行力,这是行政行为效力的法理基础。通过对行政行为事后效力的研究,形式上来看对行政行为之后的一系列行为的关系的分析和评判,实质上是为了规范行政行为,实现依法行政的目的。 Administrative action itself has no direct effect. Since the executive power can be considered as an integral part of the state power, the administrative action based on the executive power has the credibility and execution power of the state, which is the legal basis of the effectiveness of the administrative act. Through the study of the post-operative effect of administrative action, the analysis and judgment of the relationship between a series of behaviors after the administrative action formally aims at standardizing the administrative action and realizing the purpose of administering by law.
