The Multi-Regional Input-Output Table (MRIO) provides comprehensive information on the economic statistics of regions, with help of which economic structure of regions and economic relations among them are determined. Since regional tables and statistics data of inter-regional trade, which are necessary for the construction of multi-regional output tables, are not created by official institutions in Iran, using non-survey methods in regional Input-output literature is the only solution. The main aim of this paper is to provide a nine-zone Input-output table based on the CHARM method in Iran, and to estimate interregional trade. Regional accounts and the national statistical Input-output table in 2011 of Iran’s Statistical Center, have been used as statistical bases. The results of this study indicate that the total value of Interregional trade in Iran is 1000679 billion rials. The highest volume of interregional trade belongs to Khuzestan region is 337658, and the region of southern Alborz with a volume of 242225 and the lowest volume is related to the Azarbaijan region with a volume of 38,283 billion Rials. The largest volume of interregional trade of Iran is in the crude oil and natural gas sector, and then services. The highest volume of interregional trade in the Shomal, Azerbaijani, South-Eastern and Zagros regions are in the agricultural sector, Khuzestan region in the crude oil and natural gas sector, Fars region in the construction of petroleum products and chemicals, the south Alborze and Khorasan regions are in the service sector And the Central region in the manufacturing of metals and electronic and metal products.

In the mixed economic and natural resource domain, transactions on commodities, services and natural resources (water and land) are in either visible or invisible (hidden) layers. The prevailing monetary systems of macro and sectoral accounting take into account only market transactions and therefore neglect invisible transactions like intersectoral water consumption. Such a deficiency provides the ground for policymaking and water resource management to focus their attention on the aggregate data, e.g. agriculture consumes directly more than 90 percent of the total water resources. In this paper, on the basis of the extended Input – Output model, we use two approaches; namely: quantity and mixed quantity–value approaches. By using the aggregated quantity-value based Input – Output table and corresponding sectoral consumption of water (billion liters) for the year 1990, we found that sectoral water consumption multipliers and the intersectoral water consumption provide more suitable criteria for policy implications as well as for managing the consumption of water resources of the country. In addition, the agro-based industries have the largest water consumption multipliers. With respect to the hidden layer of intersectoral water consumption we found that agriculture sector supplies 92.5 percent of the total water resources while demanding 58 percent of these resources.
