概要	We investigate equilibrium locations of a spatial Cournot competition model that includes both circular city and linear city models as special cases. We find that the equilibrium location is discontinuous with respect to parameter β (β= 0 implies circular and β= 1 implies linear), and multiple equilibria appear for some range of β. The location pattern becomes exactly the same as that of the linear city for a wide range of β, while it exactly matches that of circular city only when β = 0. This implies the property of the linear city holds for non-measure zero case, while circular city does not.
