This article is focused on role of advanced I producer services in regional development in emerging market economies. The starting point of the analysis is Porter's concept on competitive advantage of regions that rests on the performance of local firms. The APS sector is discussed as a significant element of the value chain, supporting the adaptation of local agents to the emerging system market regulations and the rapid structural changes of the national, regional and local markets in Hungary. Although, empirical studies as well as statistical calculations suggested that, flexible strategies employed by service providers contributed to economic growth in regions embedded in global production systems, the national economy was basically dichotomised by the spatial centralisation of APSs.
