Fifteen years ago, Japanese companies accounted for 141 of the companies and 35.2% of the revenues of Fortune’s then brand-new Global 500 list. By 2000 their share of revenues had fallen to 20.8%, and by last year it had shrunk to 11.2%, with only 68 Japanese companies making the list. During the same period, U.S. firms’ portion of Global 500 revenues, which was 28.4% in 1995, grew slightly, to 30%. Firms from the European Union and Switzerland, meanwhile, increased their portion from 31% to 36%.
