Effect of Export Structure Changes on Output of Economic Sectors in Iran: Structural Decomposition Analysis in Input-Output Model

Export is one of the important factors affecting the production of various sectors of the economy. Therefore, this study examines the effect of export change on the production of sectors in Iran during 2006-2011 using input-output analysis. In order to achieve this goal, the country's input-output tables have been used in the years 2006 and 2011 and the structural decomposition analysis (SDA) technique has been used. Based on this technique, the total change in the country's exports is divided into two factors: the change in the total volume of exports (with a constant export structure) and the changes in structure of exports (with a constant volume of exports). The results show that the change in the structure of exports (with the constant amount of exports) increased the production of the economy by 51947.51 billion Rials. Also, changes in the volume of exports (with a constant export structure) has led to 1270999.65 billion Rials increase in the total output of economy. The total change in exports (summation of volume change and structure change effect) has also led to an increase 1322947.16 billion Rials in total output of the economy.
