Iran, located in an arid and semi-arid climatic region, has been facing a shortage of water resources for many years. This issue has become a serious issue in recent decades with the increase in the extraction of renewable water resources and has made the necessity of proper planning and policymaking in the water sector more evident than ever. In order to adopt optimal policies in this area, it is necessary to create a correct and transparent understanding of water resources and consumption in the country. Accordingly, since a considerable volume of this natural resource is used to produce economic products, examining how water is consumed in the economic system is of great importance. In this regard, the present study has examined how to calculate the competitive and non-competitive import assumption in measuring the water footprint in different sectors of the economy. For this purpose, first, the theoretical foundations of competitive and non-competitive import patterns were examined comparatively, then, in accordance with it and in order to better understand the functions of the two competitive and non-competitive patterns in policymaking and planning, a numerical example of the three-sector assumption was calculated step by step. The results showed the corresponding values for direct and indirect water consumption of each economic sector in two competitive and non-competitive import patterns. The amount of domestic water consumption of the entire economy (by separating imports in the non-competitive pattern using the proportional assumption method) was the same in both competitive and non-competitive patterns. In the non-competitive pattern, imports were decomposed into two components: final imports and intermediate imports, and intermediate imports were decomposed into two components: intermediate imports in supplying domestic production and intermediate imports in supplying exports. In the non-competitive pattern, it was shown that water consumption in supplying exports in the competitive pattern is not entirely of domestic origin; rather, part of it is domestic water consumption in supplying exports and another part is water consumption from intermediate imports in supplying exports.
