Variation theory is one of the very few ideas put forward by a Chinese comparatist.It indicates that comparative literature,especially Chinese-Western comparative literature studies no longer merely seeks homogeneity.It is also characterized by seeking heterogeneity,for Chinese literature and Western literature belong to two entirely different cultural backgrounds.In this sense,homogeneity is only relative,while heterogeneity is absolute.In this way,the variation theory will point to a new orientation for current international comparative literature studies which is viewed as being in a crisis.
