Competition and Efficiency in a Spatial Setting
研究了区域产业中空间竞争的企业模型，发现行业长期供给曲线与平均成本曲线不一致，且均衡结果源于企业各自拥有供应区域。
In this paper our primary concern is with a spatial model of competing firms in a regional industry. The firms are producing for an extraregional market and are located so as to gain exclusive access to a dispersed raw‐material input. After outlining the form of the industry long‐run average cost curve, we specify the equilibrium outcome, both for the individual firm and the regional industry. We demonstrate that the industry long‐run supply curve does not coincide with the industry long‐run average cost curve. We further show that the outcome in the spatial model results from the separation of firms, each firm having its own domain, part or all of which becomes its supply area.
