Metropolia jako źródło przewagi konkurencyjnej gospodarki regionu
Socio-economic development shows differences as regards the level and dynamics in space. Among factors which cause these differences, apart from environment's resources, labour and capital, one can also list such factors as social and institutional capital as well as the existence of metropolis. The aim of the article is to explain: 1) whether and why metropolis can be an impulse for innovative processes and modernization of the region's economy; 2) whether, after the washout phase of growth impulses from the surrounding area may experience phase of the positive impact of metropolis on the region's economy can emerge; 3) what are the necessary conditions for positive effects in the metropolis' surroundings. These problems are analysed in detail on the example of Poznań Agglomeration and Wielkopolskie Voivodship. The conducted analyses confirmed the positive impact of Poznań Agglomeration on the adjacent areas. The positive effects include: inflow of population, higher affluence, increase in the districts' (gminas) own income, higher entrepreneurship, faster inflow of foreign capital. These effects assume different directions, apart from the rings of gminas surrounding Poznań. They were more intensive in the areas south-west, west and south- east from Poznań than in those east from Poznań. A factor which facilitates positive effects of metropolis' growth in the region is sufficiently developed response environment of the surrounding areas with sub-regional centres as well as adequate internal policy of regional authorities.
