Abstract

Taylor P. J., Evans D. M. and Pain K. Application of the interlocking network model to mega-city-regions: measuring polycentricity within and beyond city-regions, Regional Studies. The interlocking network model, devised to study worldwide inter-city relations, is adapted to measure relations between cities within and beyond polycentric urban regions. The network makers are advanced producer service firms and their office networks are used to estimate positions of cities in networks. Data are collected covering nearly 2000 office networks across 200 cities in eight mega-city-regions. From these data, four estimates of the connectivities of cities (within their city-regions, nationally, at the European scale, and globally) enable unique comparisons of polycentricity at different geographical scales. The results are discussed for their policy implications. [image omitted] Taylor P. J., Evans D. M. et Pain K. Application du modele de maillage aux megalopoles: Mesure de la polycentricite dans les villes-regions et au-dela, Regional Studies. Le modele de maillage, concu pour etudier les relations entre villes dans le monde, est adapte pour mesurer les relations entre villes de regions urbaines polycentriques et au-dela. Les concepteurs de ce reseau sont des entreprises de services de pointe et leurs reseaux de bureaux servent a estimer les positions des villes dans ces reseaux. Les donnees recueillies couvrent pres de 2000 reseaux de bureaux dans 200 villes appartenant a huit megalopoles. A partir de ces donnees, quatre estimations de la connectivite de ces villes (dans les villes regions, sur le plan national, a l'echelle europeenne et mondiale) permettent des comparaisons uniques de la polycentricite a differentes echelles geographiques. Les auteurs examinent les resultats en ce qui concerne leurs implications politiques. Regions multinodales Connectivite Taylor P. J., Evans D. M. und Pain K. Anwendung des ineinandergreifenden Netzwerkmodells auf Megastadtregionen: Messung von Polyzentrizitat innerhalb und ausserhalb von Stadtregionen, Regional Studies. Das ineinandergreifende Netzwerkmodell, das zur Untersuchung weltweiter Beziehungen zwischen Stadten entwickelt wurde, wird zur Messung der Beziehungen zwischen Stadten innerhalb und ausserhalb polyzentrischer Stadtregionen angepasst. Die Entwickler der Netzwerke sind Wirtschaftsdienstleister; anhand der Filialnetze dieser Firmen werden die Positionen von Stadten in Netzwerken geschatzt. Erfasst werden die Daten von beinahe 2000 Filialnetzen in 200 Stadten innerhalb von 8 Megastadtregionen. Anhand dieser Daten werden mit Hilfe von vier Schatzungen der Konnektivitat von Stadten (innerhalb ihrer Stadtregionen, auf nationaler Ebene, auf europaischer Ebene und weltweit) eindeutige Vergleiche der Polyzentrizitat auf verschiedenen geografischen Massstaben moglich. Die Bedeutung dieser Ergebnisse fur die Politik wird erortert. Multinodulare Regionen Konnektivitat Taylor P. J., Evans D. M. y Pain K. Aplicacion del modelo de redes entrelazadas para las regiones de mega-ciudades: medicion de la policentralidad dentro y mas alla de las ciudades region, Regional Studies. El modelo de redes entrelazadas, creado para estudiar las relaciones interurbanas en todo el mundo, se ha adaptado para medir las relaciones entre las ciudades dentro y mas alla de las regiones policentricas urbanas. Los responsables de las redes son empresas de servicios avanzados de productores y sus redes de oficinas se utilizan para calcular las posiciones de las ciudades en las redes. Para este estudio se recabaron los datos de casi 2000 redes de oficinas en 200 ciudades en 8 regiones de mega-ciudades. A partir de estos datos, cuatro calculos de las conectividades de las ciudades (dentro de sus regiones-ciudades, a nivel nacional, a escala europea, y globalmente) permiten hacer comparaciones exclusivas de la policentralidad a diferentes escalas geograficas. Asimismo analizamos los resultados para conocer sus repercusiones politicas. Regiones multinodales Conectividad
