Making use of the relevant literature in the area, this paper proposes a systemic approach to the European administration. The difficulty of the research design stems from the inconsistency of the regulations European treaties exhibit, as well as from the sectorial approaches, mostly of legal nature, on the conceptualization of the EU administration. To this we add the complexity of the analyzed process which, under the conditions set by the EU enlargement tends to overcome, both in sphere and content, many of the administrations of the federal states or international organizations. The systemic model we propose is a complex system, of a mixed architecture. It is there that the self-regulatory processes have a unique specificity and make use of both a legal foundation and of complementary processes such are those of Europeanization, convergence and administrative dynamic
