Abstract:Research into administrative duty is for a long time a weak tache in the science of administrative law. There are two key defects in the research in administrative subject. On one hand,there is a contradiction between the theories of administrative duty subject and those of the administrative subject. On the other,the duty subject logically contradicts with unitary administrative subject,which leads to the question that we cannot answer:how does an administrative official convert himself into the undertaker of the administrative duty since he is not the administrative subject? This paper points out that to eliminate the disagreement between administrative subject and administrative duty,the status of administrative duty subject should be rationalized.
Key words:administrative subject;contradiction;Organizations theorie;theory of agency;theory of quasi tort
