我们研究了当区域人口的增加产生更高的城市成本时，城市间交通成本的降低对多区域经济中人口空间分布的影响。在城市数量不变的情况下，随着运输成本从很高的水平逐渐降低到很低的水平，第一阶段是大城市增长而小城市萎缩，第二阶段是大城市和小城市都增长而中等城市萎缩，第三阶段是大城市萎缩而小城市增长。此外，当运输成本从大值减少到小值时，允许城市数量变化时，它首先减少，然后增加。
We study the effects of a decrease in inter-city transport costs on the spatial distribution of population in a multi-regional economy, when a rise in the regional population generates higher urban costs. Holding the number of cities constant, as transport costs are reduced gradually from a very high level to a very low level, there is a first phase in which large cities grow while small cities shrink, a second phase in which both large and small cities grow while medium size cities shrink, and a third phase in which large cities shrink while small cities grow. Furthermore, when the number of cities is allowed to vary as transport costs are reduced from large to small values, it first decreases and then increases.
