本研究は4つの方面から空間経済学を発展させ、持続可能な都市・地域の成長を実現するための方策を考案した。1. 都市、地域の成長政策立案に結びつく空間経済学の理論を構築する。特に、賃金格差を内生的に決めるモデルを開発し、地域間の経済格差の研究ができ、経済成長理論との融合も実現した。2. 都市の開発と持続可能な振興政策を目指し、観光産業の役割、都市のデベロッパー行動、土地利用の方針についての研究を行った。3. 交通政策の分析を行うため、産業集積や防災の立場から道路のインフラ整備を検討した。4. 実証の面において、地域間の効用格差の動向や企業間関係や財の輸送費用削減を通じた集積効果を明らかにした。

We survey the recent research in the field of cake divisions and their procedures. The question is how to divide a cake among n players, so that a certain fairness is achieved, where players have individual measures on the cake, and each player only knows his own measure. The model has very wide applications, such as dividing up the property in an estate, and even in determining the border in an international dispute. We first review mathematical definitions of various concepts of fairness. Although the existence of fair divisions is proved under some mathematical conditions, their dividing procedures are not known for all cases. We summarize several existing division procedures and classify them according to their methods and purposes. Finally, we mention some related topics and describe possible future research directions.
