【摘要】This paper elucidates which agglomeration patterns exist in two-dimensional economicspace and how such patterns appear stably. Hexagonal lattices, that with and that without a bound-ary, are advanced, respectively, as practical and theoretical spatial platforms of economic activities.Agglomeration patterns on these lattices include hexagons in central place theory, but also encompassmegalopolis and racetrack-shaped decentralization. As the transport cost decreases, stable economicagglomeration undergoes the formation of the smallest hexagon and transition to patterns with largermarket areas, often undergoing downtown decay but finally leading to a megalopolis. Formulas forbreak points are provided in an economic geography model.
