摘要:In order to achieve a balanced and sustainable spatial development within the European Union,two of the basic spatial principles are: developing a balanced and polycentric urban system and promoting integrated transport and communication schemes,likely to favor the polycentric development of the EU territory.Therefore,the development of a methodology for estimating the polycentricity degree of cities becomes a topic of interest.This paper includes the presentation of such a methodology that is based on ESPON 1.1.1 program criteria,but it is original.The submitted methodology is also applied to county residences and to the Municipality of Bucharest.The methodology involves the following steps: identifying some domains characteristic to polycentricity and of some relevant indicators within such domains,the transformation of indicators’ values into scores,calculating some composite indices corresponding to the domains and the potential,which is obtained by summing these indices.The analysis of results obtained leads to certain conclusions on the formulation of some regional and national development policies.
