経済協力局
A common American interpretation of the program's role in European recovery was expressed by Paul Hoffman, head of the Economic Cooperation Administration, in 1949, when he told Congress Marshall aid had provided the "critical margin" on which other investment needed for European recovery depended. The Marshall Plan was one of the first elements of European integration, as it erased trade barriers and set up institutions to coordinate the economy on a continental level—that is, it stimulated the total political reconstruction of Western Europe.
