Comparison the results to estimate the regional input-output table with methods of CHARM and AFLQ (case study: Bushehr province)

The providing regional input-output tables with statistical method are complex and take a lot of times therefore researchers use non-statistical methods. The latest model to provide regional input-output table is AFLQ. But according to accounts of regional statistical center of Iran, in this method, export and final demand are considered as residual. While, the cross-hauling among regions is ignored. To overcome the above problems, in this research, CHARM method is introduced. This method can solve the above problems. To compare the results of two methods, Bushehr province was chosen as a case study. The results indicate that 12.7 percent of total trade volumes are belong to cross-hauling. Moreover, amounts of coefficient of backward and forward linkages in CHARM method are bigger than AFLQ method. Because in the CHARM method, the first area of input-output table, include intermediate imports. On the other hand, in two methods, ranking of sectors are different
