Globally oriented post-industrial service industry, viewed as a propulsive sector in contemporary urban economies, tends to spatially agglomerate in a few urban centres equipped with rich and diversified social, cultural, and economic opportunities and with quality-of-life assets. In these agglomerated environments, office-based service can maintain strong backward and forward economic linkages both as suppliers of intermediate and final demand goods and services, and as consumers of inputs from joint ventures, sub-contractors, and service suppliers.
