Structural decomposition analysis of Iran emission: Input - Output Approaches

In this paper is tried to analyze emission decomposition of to three effects include Leontief Structure (), Final Demand Effect () and Emission Intensity Effect () by using of structural decomposition analysis ().Then, we compare three such methods analytically and empirically through decomposing changes in Iran’s emissions. ’s method is consisted of Lasppeyres and Divisa family. this paper is used of 1986-1991 and 2001-2006 tables for estimating methods. this study is also used RAS method for gaining inside-sector exchanges matrix, to assimilate 2001-2006 tables. The results show that three above effects in-group participate increasing emission (in both comparison of 1986-1991 and 2001-2006). Whereas the sub-categories results for three methods (MRCI, LMDI-I and LMDI-II) are close to each other in 1986-1991. But above results are not true for 2001-2006.
