New Trade Theory and New Economic Geography （NEG） pioneered by Krugman are the mainstream of modem trade theory. Many economists together with Krugman have made significant contribution to the development of trade theory. By comparing the contribution made by Krugman and that of other economists, this paper analyzes the connection between Krugman＇s contribution and the works of his forerunners and peers, and points out that Krugman＇s trade theory based on differentiated goods and monopolistic competition is the most important contribution to modem trade theory in the recent 30 years.
