Research on Differentiation of Socio-Economic Development Levels among Administrative Provinces of the Central Macroregion

The article discusses findings of studies on differentiation of the socio-economic development levels among administrative provinces belonging to the central macroregion of Poland. The analysis was based on the process of formation of a selected group of socio-economic features characterizing development of administrative provinces in 1977. Three methods were employed in it and namely: normalization method, application of spatial concentration coefficients in relation to the population size, and spatial concentration coefficients in relation to area units. Application of these methods produced three different classifications revealing the hierarchy of provinces according to the achieved development level. In each case there was observed a difference in charakter of the socio-economic development between the Warsaw Metropolitan Province and the Łódź Province. This implies definite conclusions for the planning strategy in the central macroregion as well as conclusions concerning methodology of future studies on the central macroregion
