Abstract

Recently, researchers have applied the multi-regional input-output (MRIO) approach to water footprint (WF) analysis. The concept of interregional input-output (R-MRIO) was developed to analyse regional issues. Researchers have concentrated on the development of global or international input-output (N-MRIO) tables. Using the N-MRIO and the R-MRIO approach allows the study of global and regional issues, respectively. The WF is an indicator influenced by trade among nations and regions. However, the treatment of imports in an R-MRIO approach differs in whether international imports are separated or combined. We evaluate the effects of the difference between these models and discuss policy implications for the Yangtze River, China. The WF calculated using the combined type model is 11% larger than that by the separated type model. This difference can be ascribed to international imports, mainly internal consumption and interregional trade. We find that this difference affects social equity in water-abundant areas.
