This article is supported by Bourdieus theory of literary production. Therefore the main question of this research is concerned with the chiasmatic structure of this filed. First of all I start with reviewing Bourdieu's theory briefly to use it in further arguments. Also I illustrate the polarized structure of the subfield of poetry within Iranian literary associations and institutions. Malekoshoara's journal called "Daneshkadeh" is the best representative of the dependent pole and Rafat's journal, called "Tajadod", is the best representative of the independent pole of it. The first one was the place of conservative poets and the second one belonged to modem poets. Here the challenge between traditional poetry and modem poetry finds special meaning. Finally as a case study I focus on Nima, the first avant-garde poet in Iran, and try to show structural homology between literary field and the field of power in his trajectory.
