Outline of Final Research Achievements

Identifying the key sectors is one of the important issues for the regional economy. Since no industrial sector is independent within the economy, a method that considers the interdependence between sectors is preferable. For this purpose, sectors in the regional economy have been categorized according to various linkage measures proposed by the input-output analysis. Evaluation of those linkage measures has been performed from the viewpoint of their usefulness and computational load. Furthermore, a simple method for visualizing the key sectors has been proposed, that needs a relatively low computational load, and the method has been applied to analyze regional economies.

Academic Significance and Societal Importance of the Research Achievements

地域経済の主要産業の特定には，従来，計算が容易な特化係数が用いられてきた。ところが，この方法で地域経済内の産業部門間の相互依存関係を考慮することは難しい。そこで，地域産業連関モデルによる連関性指標を用い，産業部門の機能・役割・特徴を把握する方法を着想した。それらを地域経済のステークホルダーに示し，その知見を政策立案や投資計画に生かすことができる。一方，一部の連関性指標の計測に高度な計算処理能力を要する点が定量的分析の障害となりうる。その観点から，本研究では様々な連関性指標の類型化，可視化の方法を検討した。
