This study sought to evaluate the effect of changes in the composition of interregional intermediate exports and total volume of intermediate exports on the sectoral output of Golestan province and other regions using two-regional input-output model. For this purpose, at first, two-regional input- output tables for each of these region (Golestan province and other regions of country) were prepared for years 2006 and 2010 and then evaluate the effect of change in volume and composition of interregional exports on output changes in this regions using structural decomposition analysis (SDA). The results of the model for Golestan province indicate that the export of Golestan province to other regions of the country in study periods has decreased 349/09 billion Rials, and thereby total output of this province decreased 335/76 billion Rials. Also changes in composition of exports of Golestan province to other regions lead to increase 9.78 billion Rials in total output of this province.
