The WRIRIO table meets the challenge of evaluating water demand to support to various economic activities such as (1) agriculture, (2) manufacturing, and (3) service sector in all regions of Japan. This approach, which combines input-output tables and water demand analysis, overcomes the shortcoming of traditional input-output tables which do not resolve the challenge of evaluating demand of natural resources to meet economic development in each region. Regional virtual water or trade of services of water is enumerated by combining a Shikoku inter-regional input-output table and water demand analysis in same industry product. The calculated results show inter-regional trade of money and water use to support each industry. The application methodology is illustrated through the case of year 2005. The paper indicates that “water-resources inter-regional input-output table” provides a tool that allows decision makers to accurately value regional trade with consideration not only of money circulations, but also of water uses.}, publisher = {Society for Social Management Systems}, title = {REGIONAL VIRTUAL WATER OF THE SHIKOKU ISLAND : INTER-REGIONAL INPUT-OUTPUT TABLE}, volume = {8}, year = {2012} }
