摘要:Our paper analyses regional sustainable development. The understanding and the conceptualisation of the region (the natural region, the humanized region, the functional region, and the territorial-system region) have been synchronically adapted to certain development attributes, from the purely economic one to the present-day sustainable development.The main idea of our paper is that the components of sustainable development (efficient economic development, fair social development, sustainable ecological development – all these against a democratic institutional and political framework) should be implemented in regional geographical entities (the geographical regions) in order to have maximum efficiency. Our conclusion is that the sustainabledevelopment region should be perceived as an entity where we can find all the characteristics of sustainable development (economic, social, environmental development). Our approach is an incipient one without the pretension that it is definitive and exhaustive.
