The transformation of centrally planned economy into market economy brought significant changes within Łódź urban agglomeration both in the structure and strength of spatial linkages. Those changes refer in particular to permanent migrations, as well as workforce and students’ commuting flows. They lead to strengthening the role of Łódź as the cultural centre of the region and the development of linkages within technical infrastructural networks. The socio-economic transition changed the conditions of institutional cooperation, too. However, taking contemporary inter-municipal relationships into consideration Łódź urban agglomeration doesn’t seem to keep up with other Polish agglomerations, even those of significantly lesser socio-economic potential.
