石川県の基幹産業と中部圏における地域間リンケージの実態

　　This study applied the hypothetical extraction method （HEM） to the 2015 Chubu Region multi-regional input-output table （comprising 45 sectors） to examine interregional linkages connecting Ishikawa Prefecture’s core industries:production machinery, textile products, electronic components and accommodations, with the Chubu Region.　Simulated removal of each sector revealed interregional trade flows and quantified economic dependencies between Ishikawa and other prefectures within the Chubu Region.　Manufacturing sectors （production machinery, textile products, and electronic components） exhibited strong interregional linkages with both neighboring prefectures in the Hokuriku area and more distant prefectures in the Tokai area.　By contrast and reflecting its reliance on region-specific services and cultural assets, the accommodation sector demonstrated a more localized impact.　We identified two distinct patterns of industrial impact:i） affected sectors were consistent across regions, and ii） impacts varied according to regional trade structures.　Ishikawa accounted for approximately 60% of the total production loss in each manufacturing sector, while the accommodation sector accounted for approximately 75%, thus indicating stronger local dependence.　Furthermore, the affected industries in other prefectures included both highly and less specialized sectors, with varying degrees of impact.　Considering the potential economic damage from large-scale disasters, the importance of incorporating interregional trade structures into disaster preparedness is underscored.　Moreover, extending the HEM analysis to other Chubu Prefectures can enhance understanding of cross-regional vulnerabilities.　This framework supports proactive planning for disaster mitigation, industrial development, and regional collaboration, ultimately contributing to more resilient and interconnected regional economies.
