Abstract: Postmodernist Literary Theory starts from the French poststructuralist and deconstructivist literary theory, Kristeva plays a vital role in the generation of French Postmodernism Literary Theory. In France, Bakhtin's poetics introduced by Kristeva plays a landmark role in the transition of the ideological trend from structuralism to post-structuralism. On the basis of inheriting and developing Bakhtin's dialogue theory, Kristeva proposes the Intertextuality theory, Which establishes her position as the pioneer of poststructuralist literary theory and directly contributes to Roland Barthes' transition from structuralism to poststructuralism. Kristeva also inspires the master of deconstruction Derrida. The "May Storm" in 1968, the Tel Quel group's membership, acute sensibilities and academic ambition, as well as the unique experience of life as a female migrant from Eastern Europe are important reasons for Kristeva's being the illuminator of the postmodernist literary theory.

Key words: Kristeva, Postmodernist Literary Theory, Bakhtin, Roland Barthes, Derrida
