标题： City formation by dual migration of firms and workers

摘要： 本文研究了通过企业与工人迁移形成城市的一个数学模型。 新经济地理学中的中心-外围模型，该模型考虑了因地区间实际工资不平等而引起的工人迁移，被扩展以包括因地区间实际利润不平等而引起的企业迁移。 企业与工人的空间均匀分布变得不稳定，并最终形成几个城市，在这些城市中企业和工人都集聚，随着运输成本的降低，城市数量减少。 显示英文摘要

摘要： This paper studies a mathematical model of city formation by migration of firms and workers. The Core-Periphery model in the new economic geography, which considers migration of workers driven by real wage inequality among regions, is extended to incorporate migration of firms driven by real profit inequality among regions. Spatially homogeneous distributions of firms and workers become destabilized and eventually forms several cities in which both the firms and workers agglomerate, and the number of the cities decreases as transport costs become lower.
