Outline of Final Research Achievements

We developed a mathematical model and applied it to visualization of supply chains, which encourages exchange of views among stakeholders and facilitates decision making to promote an effective reduction of greenhouse gas emission. The developed model is an extension of a well-known method of input-output economics, called structural path analysis, with which a total emission can be disaggregated into the contributions of parts constituting a supply chain. Moreover, we improved an existing method for triangulating input-output tables, the results of which can be used to analyze economic structures and visualize supply chains, and demonstrated the usefulness of the improved method through empirical analyses.
