Outline of Final Research Achievements	In this study, we first conducted a review of the “Showa-era mergers” and “Heisei-era mergers” that formed the background to the formation of local governments in mountainous regions, and then conducted a survey targeting three of these local governments: (1) Nichinan Town in Tottori Prefecture, which was not included in the Heisei-era mergers and continued to consolidate public utility facilities; (2) Okuizumo Town in Shimane Prefecture, which aims to merge on equal terms and maintain multiple bases through Heisei-era mergers; and (3) Unnan City in Shimane Prefecture, where many towns and villages merged to form a new city through Heisei-era mergers. We organized and considered the detailed situation and major issues regarding regional formation and population trends, the development of local government policies, and the process of aggregation and reorganization of public utility and living convenience facilities led by these three local governments.

Academic Significance and Societal Importance of the Research Achievements	少子高齢化が進む我国において中山間地域での人口減少は著しく、特に昭和・平成の市町村合併により広域化した山間地域自治体(以下,山間自治体)では、集落及び地域コミュニティの持続に向けた方策が模索されている。人口減少と自治体財政の弱体化から、保育・小中学校・行政・医療福祉施設等を含む公共公益施設の集約と再編は避けられないが、再編が与える地域生活への影響も大きく、地域コミュニティ維持も視野に入れた「持続可能な地域計画」が求められており、本研究は平成の市町村合併時の類型別に代表的な山間地域自治体を選出し、実態調査から課題点の整理を行い、今後の山間地域自治体の地域計画・施設計画に有用な知見を整理した。
