How have a small number of "world cities" in core regions come to occupy key roles in the organization of global econommics and culture?
World cities are the control centers for the flow of information, cultural products, and finance that collectively sustain the economic and cultural globalization of the world. Key roles of the world cities are concerned with transnational corporate organization, international banking and finance, supranational govt, and the work of international agencies. World cities also provide an interface between the global and the local. They contain the economic, cultural, and institutional apparatus that channels national and provincial resources into the global economy and transmits the impulses of globalization back to national and provincial centers.
