What is the difference between old regionalism and new regionalism?

Hi,

old regionalism isn't a real concept. It is more a label given by the "new regionalism"-School to approaches and processes of regional integration in the 50s to 70s. However, new regionalism states that processes of regional integration that took place in the mid-80s until now, differ strongly in their quality. They criticize the "old regionalism" for being eurocentristic and not being able to see different forms of regional integration.

Björn Hettne and Frederik Söderbaum have written a lot about the new regionalism approach, what is worth reading.
