Outline of Final Research Achievements

This study verified settlement intention theory, focusing on cognitive biases and the structure of subjective well-being. We found that descriptive norms shared by the community increase the intention to settle in an aging and depopulated area, while injunctive norms decrease the intention to settle in the same area. In a survey conducted in the areas affected by the Great East Japan Earthquake, it was found that when social networks were lost due to displacement, the decreased sense of well-being could be compensated by a sense of satisfaction with the new physical environment. Extreme smart city policy does not increase the intention to live in the city. We also found that the aging of the urban area can be caused by both active and passive settlement.

Academic Significance and Societal Importance of the Research Achievements

現在，日本では多くの地域で高齢化が進んでおり，そのような地域の人口維持が重要な社会的課題になっている．そうした地域において，効果的な人口維持策を検討するためには，人々の定住意図の形成メカニズムやその性質を明らかにする必要がある．本研究は，この点で社会的意義を備えている．また，これまでの定住研究では理論的側面の検討が十分だったとは言えない．そこで，本研究では定住決定が一つの意思決定であることを踏まえ，意思決定理論の枠組みを援用して定住意図の形成メカニズムを検討した．すなわち，認知バイアスや記憶といった心理要因の影響を検討した．本研究の学術的貢献はこの点にある．
