In the present study, an application of multilevel modeling approach to the input- output analysis are presented First, the regional input-output table of all provinces in Iran was extracted based on the Adjusted Flegg Location Quotient Method (AFLQ). Second differentiation in the Leontief technical coefficients and the backward and forward linkages among various activities and sectors of all provinces were examined using the 3-level and 2-level models. The results of variance analysis among the different levels reveal that activities, sectors and provinces are heterogeneous in terms of the mentioned indexes. Therefore, activities aggregation and spatial aggregation of the regional input- output tables raise errors and reduce the accuracy

The present study aimed at understanding interactions and linkages between the sugar sector with other economic sectors, and the influence of sugar import reduction on the economic value added. To achieve the purpose, the Input-Output table of Iran for the year 2006, Leontief inverse matrix and hypothetical extraction method were used. Based on the results, sugar industry has the most forward linkages with “Manufacture of food products and beverages,…”, “husbandry, aviculture,…”, “cultivation, horticulture”, “bakery products” and “restaurants”. This sector has also strong backward linkages with “cultivation, horticulture”, “chemicals and chemical products”, “other services”, “transport and telecommunication” and “financial services, insurance and bank”. Furthermore, either one unit increase in the final demand of sugar or one unit decrease in the sugar import increases the output of whole economic, agricultural and fishing, industry and mining, and services sectors by 2.3060, 0.6019, 1.4331, and 0.2710 unit, respectively. The increasing coefficients of the value added for the above sectors are 0.4308, 0.3700, and 0.1992 unit, respectively.
