Measurement of dependence of economic sectors of Ilam province on intermediate imports using the data-output table

The purpose of this study is to measure the dependence of the economic sectors of Ilam province on the importation of intermediaries from three dimensions of source, destination and policy. To do this, a regional data-output table is designed with non-survey-based methods. One of these methods is the modified method of calculating regional tables in terms of mutual concurrent trading transactions, which is the adjusted form of commodity alignment method. Using the non-statistical Cross-Hauling Adjusted Regionalization method (CHARM), and national and regional accounts in 2011, this study aims to compute the input-output table of Ilam. The results indicate that “Making chemical materials and chemical products” among other economic sectors of Ilam is a sector with the most dependence on intermediary imports from the source dimension. Moreover, the “Residential buildings” sector is the highest dependent on intermediary imports according to the destination aspect. In terms of import dependence from political aspect, the highest dependence on imports occurs in “water, electricity, gas”, “industry” and “construction” sectors. This means that by selecting each of these sectors, as the policy sector in the province, imports of intermediary products would increase highly
