Outline of Final Research Achievements

In order to clarify the effect of road infrastructure on gross regional product(GRP), this study developed a methodology for ex-post clarification of the productivity effect of road access using a statistical causal discovery method, and verified it using real data. For the former, we found that there is a stable range of regression variation in the estimation model. For the latter, accessibility by road was found to have a significant effect on regional GDP only when road distances between municipalities and prefectural capitals were used. The results also indicate that there is heterogeneity in the productivity effects of road accessibility across regions. The results indicate that there is an effective combination of regions that can be linked by road accessibility.

Academic Significance and Societal Importance of the Research Achievements

統計的因果探索により,道路アクセスの良さと地域生産額の間に,正の生産力効果が確認できた.ただし地域生産に貢献する道路アクセスは,各市町村と都道府県を代表する県庁所在地を結ぶものであり,その他の市町村とのアクセス改善が地域生産に資するわけではないことが明らかとなった.この点は地域政策の立案時に十分に注意する必要がある.得られた知見は,地域間道路の整備目的と整合的に活用することで,インフラストック効果に関する議論を整理できると思われる.
