SUPPLY ARMS AND OPTIMAL SPATIAL STRUCTURE*
研究一个多工厂生产商在独占区域中，如何通过调整工厂规模、频率、供应区域大小和形状来最大化利润，并发现最优结构随外生价格水平变化。
ABSTRACT. A multi‐plant producer has sole access to a region, and each of the plants processes a raw material which is drawn from its own exclusive supply area. Under these conditions what spatial structure of production (in terms of plant scale, plant frequency, supply‐area size and supply‐area shape) will enable region‐wide or multi‐plant profit to be maximized? The form of this optimal structure is shown to vary with prevailing level of price, which is exogenously determined.
