In addition to the class gap, Iran's border regions also suffer from regional SPATIAL inJUSTICE. In the field of social JUSTICE and urban SPATIAL JUSTICE, a lot of quantitative research has been done in various fields of social sciences, urban planning, etc., but regional SPATIAL JUSTICE" has been neglected. This research examines social policies regarding the development of border regions with an emphasis on regional SPATIAL JUSTICE with the qualitative method of critical discourse analysis with the Farclough-Laclave and Mouffe approach at the levels of description, interpretation and explanation.In the post -revolution 5-year development plans, there is no article or note regarding the development of border areas, except, a part of Article 204 of the Fifth Development Plan, which deals with investment and sustainable livelihood of border dwellers and border industrial towns. Social policies and development plans after the revolution, influenced by layering discourses. in the upper layer, fixed supra-discourse of the government of the Islamic Revolution stands, while in the middle layer, there are variable government discourses, and in the inner layer, there are development discourses. This layering creates a discourse order in which development plans for border areas are articulated as plans emphasizing on regional SPATIAL JUSTICE. In these social policies, which are under influence of ideological- discursive formulation, posterior and distributive JUSTICE was preferred to a priori and procedural JUSTICE. But, the development of Iran's border regions with an emphasis on regional SPATIAL JUSTICE, requires a combined approach of procedural-distributive JUSTICE and the rule of an evolutionary discursive order instead of an antagonistic one.
