Territorial-administrative delimitation is a system of territorial organization, which serves as a legal basis for the functioning of local administrative institutions. Effectiveness of these institutions depends from rationality of territorial-administrative delimitation. Territorial-administrative delimitation follows location of local public administrative authorities at the first and second levels in a specific territorial, juridical and administrative framework for effective administration of locality, and in order to achieve principles of local autonomy and decentralization of public services. It is an axiom that the Republic of Moldova must give up the soviet system of territorial-administrative delimitation. It is more complicate to find the ideal model, which will correspond to new provocations that will face the Republic of Moldova in future.
