Recent trends in the globalization of production and the formation of
regional coalitions has brought into question the suitability of the n
ation state as the relevant scale for regional analysis. Economic acti
vities are increasingly occuring within supranational spaces or region
states, which act as mediators between the national and the internati
onal economy. The rise of the region state has provoked fears that the
postwar world order is disintegrating into closed trading blocs. This
paper examines the spatial structure of region states and the role th
ey play in the international economy, based upon international trade f
lows 1970-90. Six region states are identified, arranged around the co
re market countries of the US, Japan, Germany, France, UK and the form
er USSR. Trade linkages between region states are hierarchically arran
ged, revealing a bipolar structure of Pan-Pacific and Pan-European tra
de. We also found an increase in the trade between region states relat
ive to the trade within region states, indicating that the emerging re
gionalization is associated with stronger global interdependencies.
