Outline of Final Research Achievements

In the long-term population decline, a major issue is the implementation of urban shrinkage policies. There are many negative views on the shrinking of cities. However, if it is confirmed that the shrinking of cities is a factor that gives the competition for population advantage, each local government will try to change the urban structure. In recent years, local governments have been competing with neighboring local governments to implement housing subsidy policies, but they have not achieved significantly positive results contrary to their original goals. In the future, further analysis is needed on what promotes the transformation of the city structure to a level commensurate with the population size.

地方財政

Academic Significance and Societal Importance of the Research Achievements

長期的な人口減少にともない、都市の空間的範囲の調整、人口規模に適する水準まで縮小を図るための政策の着実な実行が重要となる。しかし、再編にともなう負の影響が過度に懸念されたり、あるいは過度な楽観論が選好されたりすることで、地方自治体では人口構造の変化に対応する政策への転換がほとんど実行されていない。本研究では今後の都市の在り方を模索していくうえで、エビデンスに基づく政策の提示とともに厳しい財政状況下にある地方自治体の持続性と効率的な行財政運営にも貢献するものである。
