Outline of Final Research Achievements

The development of international transportation infrastructure such as airports and ports affects not only the international economy but also various regions in Japan.
Similarly, urban transport policy such as road and public transport influence to intercity or international economic relationship. However, the conventional evaluation methods were not able to depict such effects properly. This research combined the existing spatial economic models and developed the new methodology to assess the above issues.

Academic Significance and Societal Importance of the Research Achievements

・産業連関表や地域間交易データが不完全な場合においても，モデルのキャリブレーションが可能となり，任意の空間規模に適用可能な，空間スケール自由度の高い空間経済（SCGE）モデルを構築した．これにより，データ整備環境が乏しい途上国への適用や，道州制の広域地方圏設定パターンの代替案比較など空間集計単位を変えることが必要な分析が可能となった．
・空港や港湾などの国際交通基盤整備が国際経済のみならず国内各地域に及ぼす影響を，「集積の経済」を反映した理論と整合的に評価できる手法を構築した．
