LOCATION, THEORY OF PRODUCTION, AND VARIABLE TRANSPORTATION RATES*
在三角形空间背景下，研究了运输费率随数量和距离变化时，区位与产出决策相互独立的条件，发现当生产函数具有线性扩展路径且运输费率弹性和需求价格弹性均为常数时，独立性成立。
ABSTRACT. The question of what conditions insure independence between location and output decisions is investigated within the context of triangle space. Assuming that transportation rates vary with quantity and distance, it is shown that this independence is insured if the production function generates a linear expansion path and the following are all constant: transportation rate elasticities with respect to distance and quantity, and the price elasticity of demand for inputs.
