The article provides a comparison of the dynamic increase in the number of enterprises relative to the working-age population in the private sector in the years 2001–2004 (the immediate pre-accession period) and 2004–2007 (the immediate post-accession period). The study was conducted with regard to the main sectors of economic activity (agriculture, industry, lower-order services and higher-order services), as well as the functional diversity of municipalities, or gminas (urban and suburban categories, transportation corridors, tourism, etc., for a total of 16 categories). The study indicates a decline, inertia, spatial polarisation and tessellated spatial structure of the development dynamic of private enterprises.
