Abstract: The touristic regionalization, in most cases, is performed by taking into account the tourism potential as main reference, in this respect numerous methodologies having attempted to quantify as balanced as possible both the natural tourism potential and the man-made one. Beyond its great theoretical importance, their actual, practical and statistical value is yet limited, given that all economic and socio-political analyses, reports and comparisons have a mandatory administrative dimension, too. These present realities constitute the main reason why we believe that a deepening of regionalization which takes into consideration, more than others made so far, the administrative component, on the one hand, and the actual revaluation, on the other hand, embodied in the existence of specific infrastructure, which together with the tourism potential shall determine the attraction of tourist flows. In this respect, we tried to consider, to share and to model a large number of indicators to reach an outcome which provides a more real, synthetic and complete image (8 data sets were structured and combined, calculating 13 indicators, subsequently synthesized into 5, which led to the preparation of maps: afterwards these were overlapped for county level, respectively their average at the level of development regions. Such a regionalization also reflects the real role that tourism plays in the economic balance of counties, respectively development regions.
