Motivation: Regional cohesion constitutes an important aim of European policy. Nevertheless, it is mainly assessed in terms of economic results analyzed at an aggregate level. Sectoral determinants of interregional differences are often neglected. However, as the structural convergence concept suggests, sectoral features may be decisive for minimizing interregional disparities.Aim: The paper searches for connections between two dimensions of economic regional cohesion in the EU: economic results and structural features. It tests a hypothesis about the coexistence of high diversification in GDP per capita and in the sectoral structures of employment. It is also aimed at identification of sectoral features that characterize the best performing economies.Results: The research results confirm a positive correlation between interregional differences in production and in sectoral structures. It indicates knowledge-intensive market services as a sector the most favorable for economic results. Moreover, it also finds that a high concentration of sectoral structures coexists with a high level of regional GDP per capita and economic efficiency.

The main aspect of nearly all forms of economic activity is a sphere of provisioning. It plays an essential role in retail enterprises, the main task of which is to transform production assortment into a commodity searched by buyers. Efficient provision constitutes necessary condition to realize the task. Results of the own research which was aimed to specify factors of choice of a source of provision by food retailers in podkarpackie voivodeships were presented in the paper. A self-esteem of level of provision of the reviewed companies was compared with assessment made by clients. Additionally, the evaluations were compared with results concerning real purchases realized out of a shop in which it was planned to buy commodities and resulted from lack of assortment in the shop.

The Halych site is located on a cape of a high (4th) terrace on the right bank of Dniester River (fi g. 3). During the survey, the Polish-Ukrainian expedition explored 340 m2. It is a non-defi ned closely fragment of a site largely destroyed by industrial exploitation of loess for the local brick plant (fi g. 2, 3). The relics of Paleolithic settlement appeared on 3 levels, at a depth of 200–230 cm from the surface. They constituted 1st cultural stratum in the lower part of the Rivne type fossil soil (fi g. 5, 6), created during warming and humidizing of the climate, related to the Lascaux interstadial in Western Europe. The oldest of the discovered levels (Ic) has remained in a form of gray spots, single bones and dispersed fl int products (365 specimens). The middle settlement level (Ib) was best preserved and included the largest number of fi nds. It included the hearth no 2, fl int products grouped around it (2132 specimens) and a concentration of more than 800 bones, almost exclusively mammoth ones (fi g. 13). The youngest settlement level (Ia) has remained in a form of hearth No 1, concentration of fl int objects (2199 specimens) and dispersed, single bones (fi g. 14). The inventory from Halych shows close typological links both to the Dniester Molodova culture sets (for instance Molodova V, ex. VII and VIII and Mežygircy I), being a result of spreading of Gravette tradition from Western to Eastern Subcarpathian after 25 kyr. As a result of this process Molodova culture appeared in the area of middle and upper Dniester River. Also typological similarities of mid-European Pavloviene (Pavlov, Dolní Věstonice), should be noted. Considering the radiocarbon and thermoluminescence dating it can be assumed, that the upper cultural stratum from Halych has three phases, and the youngest settlement phase (Ia), should be dated for the period between 19th and 21st millennium BC., the middle phase (Ib), between 23rd and 24th millennium BC, while the oldest (Ic), from 24th to 25 000 years BC. Thus what remains, are relics of a local sequence of Gravettian culture, from the period between 19 to 25 000 years ago. Upper Paleolithic settlement process had three phases there, and the youngest settlement phase can be dated for 19 and 21, 23 and 24 thousand years BC while the oldest for 24 to 25 thousand years BC. Artykuł omawia wyniki polsko-ukraińskich badań prowadzonych w latach 2000– 2004 na stanowisku kultury graweckiej w Haliczu, położonym na wysokiej, lessowej terasie Dniestru. W jego obrębie odkryto koncentrację około 800 fragmentów kości mamuta oraz inwentarz składający się z ponad 6000 wyrobów krzemiennych zlokalizowanych w sąsiedztwie dwóch palenisk. Na podstawie analiz termoluminescencyjnych i radiowęglowych wyznaczono trzy fazy zasiedlenia tego miejsca datowane od 25 do 19 tysięcy lat p.n.e.
