We use regression and factor analyses to explain intermetropolitan variation in the proportion of jobs in disaggregated service sectors in American metropolitan areas. Central place theory postulates of centrally located establishments serving a surrounding complementary region partially explain the positive relationship between metropolitan size and the proportion of jobs in an area in services. Regional variation in demand following several decades of substantial shifts in population and economic output is an additional influence. Intermetropolitan clustering of service sectors is also occurring. A factor analysis of employment proportions in twenty-two disaggregate service sectors identified five intersectoral service clusters. The factor analysis accounted for substantially more variance than the regression equations. We interpret this result as evidence of the emergence of service-based spatial industrial complexes. We argue that agglomeration of information-intensive intermediate services is driven by an attraction to labor markets endowed with pools of skilled professionals who can flexibly apply their talents in a variety of sectors. Unusual demographic characteristics of some metropolitan areas probably explain clusters of final demand services. 相似文献

The article draws on a thematic evaluation of Research Technological Development and Innovation (RTDI) related actions supported by the Structural Funds to assist declining industrial areas or Objective 2 regions, during the period between 1989 and 1999. Over the 10 year period, three main approaches were identified in Objective 2 regions, the last two becoming predominant during the latter part of the period: technology push with funding of large projects such as science parks and research facilities; technology transfer with measures to disseminate technology; and demand pull with clearly identified and self contained RTDI priorities. While drawing lessons from the last decade, the paper also integrates some preliminary observations on structural funds investments for innovation during the current 2000–2006 programming period and concludes with a review of possible scenarios for the further development of RTDI in lagging regions in the framework of the Lisbon Strategy. 相似文献
