The public administration system is "a system of social organization based on relationships that exist between people who carry a specific activity called pub­ lic administration ". The administration is both part of the social environment and social environment itself. Its ultimate goal is to serve the society that created it and to meet the human legitimate rights and interests. Administration is a body in a set of social structures having a primary place in the global society, which is inserted from other organizations or human groups structured hierarchically, lie social environment and its evolution influence the activity and the structure of Administration, but at the same time, the Administration influences the social environment. Administration and its institutions is presented as a structured set of ojficials and social bodies through the mutual relations with other organizations within the global society in order to perform the tasks pursued jointly or separately. Thus, there is a close link between the administrative phenomenon and the global society, as Administration is determined by the social organization whose demands it meets, as well as the collective behavior, and, therefore, we can real­ ize the sociologic explanation of the administration phenomenon. As part of the social system, public administration has two indispensable essential components and namely: the structural-organic and the functional elements. The compatibility of the Public Administration system with the overall social one presupposes the mutual admittance of the needs they both have in common. Tliis knowledge is achieved by the spread of the information flow in both direclions within the mentioned systems, as well as, through multiple forms of social participation of the public administration system.
