A new set of indices for monitoring the effects of implementing new regional development policies of the European Union, as well as other sectoral policies with territorial effects, resulted into the creation of new flexible systems, able to increase the administrative capacity to access structural and cohesion funds. The novelty of this study consists of the original methodology embedding mathematical methods (i.e., the ELECTRE and the index of development methods) in a GIS in order to produce hierarchies of the territorial indices at the NUTS levels III and V, displayed as charts and maps underlining the disparities between the socioeconomic, cultural and environmental aspects of the development. Our results suggest that the Romanian poorly developed regions are located in the south. Methodologically, the potential of the approach developed by this study recommends its usage as a planning tool of regional development. The limitations are due to the sparse monitoring and lack of data covering Romania.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
