AN ANALYSIS OF TWO‐CENTER COMPETITION
用Lotka-Volterra方程构建两级中心竞争模型，纳入规模经济、消费者外流和距离参数，并估计外流率以分析区域承载力变化。
ABSTRACT This paper analyzes the competition between the two centers which belong to different hierarchical levels. A two‐center competition model is constructed by applying the Lotka‐Volterra equations. This model includes as parameters the scale economies of central places, the consumer's outflow from the region, as well the distance between centers. As it is assumed in this model that the carrying capacity of the region will be affected by the consumer's outflow rate from it, the outflow rate is estimated by a demand generation model and then incorporated into the two‐center competition model.
