摘要：

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 beta (beta = 0 implies circular and beta = 1 implies linear), and multiple equilibria appear for some range of beta. The location pattern becomes exactly the same as that of the linear city for a wide range of beta, while it exactly matches that of circular city only when beta = 0. This implies the property of the linear city holds for non-measure zero case, while circular city does not.
