Abstract: As the development of social identity theory, social psychologists have focused on the relationship between ethnic identity and inter-group attitude. Social identity theory suggested that group identity was the basis of inter-group attitudes, ethnic identity was too strong to lead to negative intergroup attitudes. A developmental perspective offered a model of positive role of Ethnic identity on intergroup attitudes. The recent studies have provided evidence that a well-developed ethnic identity is associated with positive intergroup attitudes.

Key words: ethnic identity, intergroup attitude, developmental perspective
