| Research Abstract |
A new method for material flow analysis(MFA), termed the unit physical input-output by material(UPIOM), was developed. The UPIOM diagram can effectively visualize inter-sector material flow, in particular, when there are a lot of sectors and loops. The UPIOM diagram can be complementary to the Sankey diagram, which is well-known in the literature of MFA. In constructing the UPIOM and Sankey diagrams, it is vital to reduce information and/or place boxes representing sectors at appropriate positions. New methods for carrying out these vital steps were developed. These methods are triangulation of input-output tables, structural path analysis, and path-based matrix decomposition analysis(PMDA). These methods were applied to MFA of metal species and carbon in Japanese economy.
