Outline of Final Research Achievements

In this research, we estimate value added, employment, environmental emissions, and resource use embodied in iPhone. We have integrated global multi-regional input-output model and company level financial and supply chain database to trace iPhone supply chains.

Academic Significance and Societal Importance of the Research Achievements

サプライチェーンで排出される環境負荷や付加価値は、非常に重要なトピックの一つとなっている。例えば、TCFDやTNFDなどで企業のサプライチェーンでの環境負荷の把握が求められている。また、付加価値の文脈でも多くの国際機関で、付加価値貿易の分析が行われてきた。本研究で明らかにしようとしたスマートフォンという個別の製品の世界レベルでのサプライチェーンとそれに伴う環境負荷や付加価値の把握も先駆的なものであった。ただし、当初考えていた分析ではすべてを達成できず、今後の研究発展のために、意義深い研究となった。
