Abstract: This paper shows the application of mixed-unit input-output model in regional water accounting. The main advantage of this model consists in being able to replace non-homogeneous flows of goods and services with significant variations in average prices of water among the different purchasers by the volume of required water in the traditional input-output analysis. In this paper, the hybrid system is constructed using various data sources such as inter-regional input-output table of Yoshino River Basin, Japan, and water use account in each industrial sector, including in household purpose. Water demand of each product is analyzed using the mixed Leontief inverse. The calculation results show that agricultural products are responsible as majority of the total water used in Japan’s economy. This current study demonstrates a combination of tools and techniques that are developed in the fields of water resources engineering and input-output economics in addressing major water policy imperatives. The results are expected to inform the water policy makers in prioritizing major areas needed to understand the water impact of the regional economy.
