The article contains the author’s vision on the characteristics of the concept of administrative transparency, which occupies an extremely important role in the organization and functioning of public administration. Its integral elements are also identified, starting from the essential vectors of a democratic society which tends to efficient governance. Thus, the concept of transparency becomes a priority aspect on the agenda of a more democratic and more efficient model of public administration activity. At present, the concept of transparency corresponds to contemporary principles of public administration and administrative law; it increases the motivation in the decision making process and citizens’ accessibility to administrative documents, develops security means within administrative procedures. It is defined in multiple ways, but it implies the same meanings: transparency is the key element in exercising the right to access to information; it is the key element to control, to check the public administration actions, to make possible institutional accountability through consulting and participation, which have as a positive impact the citizens’ increasing trust in authorities. As the same time, the author argues the idea that the right to access to information and participation in decision making are only two fundamental rights whose exercise is beneficial not only for citizens, but mostly, but also for the public administration, which should change from a controlled and close administration into an open, transparent and accountable one.
