Outline of Research at the Start

外来種防除の推進に向けて報奨金制度が導入されているが、報奨金制度の効果や妥当性は検証されていない。本研究では、アライグマを対象として、報奨金制度の導入が外来種の捕獲数等に与える効果を定量的に明らかにする。続いて、どのようなデザインの報奨金制度であれば防除の実務者の協力意欲をより喚起できるか、選択型実験などの表明選好法を適用して明らかにするとともに、現行の報奨金制度とのギャップを解明する。最後に、どのような成果が得られる防除であれば納税者の理解が得られるか、一般市民の選好評価から解明する。これらの知見に基づいて、防除の推進に向けたより実効性のある報奨金制度のデザインを提案する。

Outline of Final Research Achievements

This study provides empirical evidence on the effectiveness and optimal design of bounty programs for managing invasive species. Analysis of raccoon management data from Hokkaido revealed that current bounty programs increase capture numbers but do not lead to a reduction in agricultural damage. A discrete choice experiment with the general public across Japan showed that reducing damage caused by invasive species such as raccoons improves public welfare, as does the management of native species such as bears. However, some invasive species were found to have limited perceived impact. Among various support options, financial assistance for damage prevention was most preferred, while bounties for captures received moderate support. These findings highlight the need for outcome-based policy design grounded in actual effectiveness.

Academic Significance and Societal Importance of the Research Achievements

外来種による被害が全国で深刻化する中、本研究では、駆除を促進するために導入されている報奨金制度の効果と、より望ましい制度設計を明らかにした。既存の制度は捕獲数や努力量の増加にはつながっているものの、本来の目的である農業被害の軽減には効果がないことが判明した。これは限られた予算で運用される外来種管理政策の見直しが必要であることを示唆している。また、全国の市民を対象とした調査により、被害軽減を望む動物の種類や、求められる支援策の傾向も明らかになった。その結果、被害防止作業への支援が最も支持され、捕獲への報奨金は中程度の評価にとどまった。これらの成果は、実効性の高い政策づくりに貢献するものである。
