Outline of Final Research Achievements

In this study, the world's 43 countries were divided into two groups by a cluster analysis based on the similarity of production structures obtained from the multiregional input-output table. The two groups contain various countries with different levels of economic development. it is clear that there is no relationship between the level of economic development and the similarity of production structures. Furthermore, there are differences in carbon emission structures between the two groups, and the sectors that should be targeted in emission reductions for each group were identified.

Academic Significance and Societal Importance of the Research Achievements

気候変動を緩和するための国際的な枠組みとして、京都議定書とパリ協定が代表的な例として挙げられるが、このような枠組みは、従来はGDPやGNIなどの経済発展度の指標に基づいた国際的な枠組（例：京都議定書）による排出削減が行われてきた。しかしながら、本研究の成果で示すように、経済発展と産業構造の間に必ずしも有意な関係があるとは言えず従来の経済発展の指標に基づく国際的な枠組みは重要ではないことが示され、産業構造に基づいた枠組みの重要性が確認された。
