The permanent tendency of public administration reform and development is characteristic of the modern society. In these circumstances, deep knowledge of the administrative phenomenon for ensuring a balanced organization and a perfect running of the public administration is required. The task is accomplished by the science of administration, which aims at a complete study of the theory and the practice of the public administration, trying to emphasize on the regularities that represent the basis of its organization and running. The knowledge of the theory and practice of other countries’ administration is particularly important for the process of the creation of a modern administration in the Republic of Moldova. From this point of view, European community countries present special interest for us. Therefore, we make an analysis of the evolution of the public administration theory in Great Britain, France, and Germany.
