Influence range of towns in the light of economic linkages – an example of small and medium-sized towns in the Lodz voivodeship

The main aim of the author was to determine the influence range of towns in the light of their economic linkages. The text is part of the author’s larger research project which focuses on the problem of identification and delimitation of functional areas of small and medium-sized towns. An important element of the analyses, apart from their cognitive aspect, is a proposal of an independent tool to measure the phenomenon of economic linkages with the use of data included in the REGON (National Register of Business Entities) database. All the analyses have been conducted on the basis of 38 small and medium-sized towns in the Lodz voivodeship.
