Outline of Final Research Achievements

This research developed a model that considers ecological and economic systems to be a unified system. A unified ecological economic system captures the inter-dependencies embedded in the system. This research developed a modeling method that synchronizes system dynamics with input-output table to capture the inter-dependencies. While the former can capture the non-linear dynamics of ecological systems, the latter can capture the impact of restoration measures and cost allocation principles on the regional economy by industry. The model was developed through its application to the Seine estuary and its surrounding local economy in which Soles are primary commercial fish. The model simulation revealed that the impact of cost allocation varies across the industries.

Academic Significance and Societal Importance of the Research Achievements

生態系と経済はお互いに影響しあっており、経済への影響を考慮しない生態系への対策、生態系への影響を考慮しない経済政策、ともに誰も望まない結果に陥る可能性がある。このため、生態系と経済システムを一つのシステムとして捉えるアプローチが必要である。本研究で開発した生態経済モデルは、セーヌ河口域とその地域経済に適用したものであるが、他の事例にも広く活用できるものである。特に、産業連関表は全都道府県、また一部の自治体で整備されており、適用しやすい手法であると考えられる。
