OPTIMUM LOCATION AND THEORY OF THE FIRM UNDER A REGULATORY CONSTRAINT*
研究了空间因素对受管制企业的影响，发现A-J效应在空间设定下不变，且当资本与劳动互补时，管制回报率与无约束回报率差距越大，企业最优选址越靠近产品市场。
ABSTRACT This paper attempts to incorporate space in the theory of a regulated firm. It will show that the A‐J effects are not affected in a spatial setting. In addition, it will also demonstrate that as the difference between the regulated fair rate of return and the unconstrained profit‐maximizing rate of return on capital becomes greater, the optimum location of the regulated firm moves towards the site of the product market, if capital and labor are complements (substitutes) and if marginal transportation costs (with respect to distance) are an increasing (decreasing) function of labor usage.
