Academic Significance and Societal Importance of the Research Achievements

本研究では、不動産に関する所有者の権利と義務をどのように考えるのか、個人の権利と公共の福祉をどのように均衡させるのか、空き家対策をどのように使い分けるべきかという学術的な問いを立てた。これらは、空き家対策の全体理念に触れるばかりでなく、人口減少時代を本格的に迎えつつある日本が避けて通れない問いでもある。本研究は、これまで明確に意識されてこなかった公正性、有効性、効率性という評価基準を踏まえて行ったため、研究成果は、空き家対策の積極的展開に貢献すると思われる。
国内の管財人制度による空き家再生事例が限られているため論文は少なく、米国の制度についても内外の論文は限られており、本研究は新規性が高い。
