The study draws a quantitative picture about the institutional actors of the private sphere of the economy in the three Szekler counties after the political transformations, it introduces the longitudinal trends of business foundations, and presents statistics related to the viability of economic corporations. Observing the map designed to illustrate the number of enterprises per one thousand inhabitants it could be concluded that the differences perceived in the intensity of entrepreneurial activity in the various communes cannot only be explained by the unequal distribution of resources, but specific structural differences of society must also be taken into consideration. Models created to provide a more accurate picture show that more intense entrepreneurial activity is likely to be found in settlements located in the center of the county, with a better infrastructure, higher reproduction indicators, and with a more significant, better qualified population capable of work.
