Outline of Final Research Achievements

In this study, we aimed that (1)construct comprehensive database for marine resources depletion and international trade, especially resources export, and (2)construct formal theoretical model and sophisticated econometrical model for analyzing the relationship among resources trade and depletion, and (3)provide some political implication about resources conservation. Through the project, (1) we had constructed comprehensive database about marine resources trade (especially export), resources catch, and resources condition (depletion), and had shown the detailed situation about regional resource depletion and export pattern. Moreover, (2) we had revealed concrete relationship between marine resources export and resources depletion. This implied marine resources export tend to cause overfishing and damage export countries' own resources. however, (3)we could not provide sufficient political implication for resources conservation because of the impossibility of field survey by COVID-19.

Academic Significance and Societal Importance of the Research Achievements

海洋漁業資源の枯渇は世界中で深刻な問題となっているが、その原因については様々な議論があり、足並みをそろえた有効な施策がとれていない。もし本研究で一定程度確認できた、「漁業資源の輸出が実際にその地域の海洋漁業資源の枯渇に影響を与えている」ということが確かであるならば、貿易制限も含めた効果的な資源保護の施策に対する示唆をもたらすであろう。本研究の内容、特に貿易と漁業資源枯渇との関係に関する類似の研究は非常に少なく、新たな知見と視点を提供するという意味でも学術的意義は高かったのではないかと考えている。しかし、コロナ禍により現地調査が不十分になってしまし、政策への示唆は弱くなってしまった。
