Under Polish administration system, they can be defined as such services, which can be situated in several towns in voivodeship (region, province), but not in every capital of poviat (county). The transformation of civilization influenced changes in the hierarchical model of settlement network, but the regularities are still valid. Therefore, the question appears, to which extent the regularity relate to the concentration of services in hierarchical centers. Although a significant part of the economic literature concerns the hierarchical settlement network models, the issue of sub-regional centers in Poland defined by sets of located or desired services was not researched recently. The role of hierarchical service model in regional policy was research to a small extent. Models derived from Christaller's central place theory are used not only to describe reality, but also in planning. In Germany simple criteria of population and distance determine the planning rank of centre and location of public services. It is different in Poland. The centers of different levels determined in the spatial development plans for voivodeships are not commonly used as a tool of localization services policy. The objectives of the presented research were to verify: 1) whether regularities of the hierarchical model for localization of services are still valid at the sub-regional level in Poland, 2) to which extent the regional planning operates here with the model of service, 3) whether this model is a tool for localization of services. Methods of the research include identification and classification of sub-regional centers on the basis services located there and analysis of spatial development plans for voivodeships. Research has shown that there are towns, which can be named sub-regional centers complete and incomplete, depending on complete and incomplete equipment at a set of typical sub-regional services. Hierarchical centers determined in the regional planning are more often treated as centers of development, than of the service.
