论文摘要
我们考虑了一个具有两个区域间接近结构的经济地理模型：一种管理货物贸易，另一个领导着各个地区的生产外部性。我们研究了后者的引入如何影响内源性聚集的时间和跨地区工人的空间分布。随着运输成本的下降，经济经历了渐进的分散过程。当区域间贸易和/或生产外部性产生高运输成本时，会出现单一以单中心的聚集，而当这些成本忽略不计时（即距离死亡时）时，就会发生统一的分散体。在多区域地理学中，随着经济融合的增加，生产外部性的网络结构可以确定工人的地理分布。如果生产外部性仅受地理距离的控制，则以郊区化的形式出现单一中心的空间分布。但是，如果通过紧密的生产连接连接地理遥远的区域对，则多用中心的空间分布将是可持续的。
We consider an economic geography model with two inter-regional proximity structures: one governing goods trade and the other governing production externalities across regions. We investigate how the introduction of the latter affects the timing of endogenous agglomeration and the spatial distribution of workers across regions. As transportation costs decline, the economy undergoes a progressive dispersion process. Mono-centric agglomeration emerges when inter-regional trade and/or production externalities incur high transportation costs, while uniform dispersion occurs when these costs become negligibly small (i.e., when distance dies). In multi-regional geography, the network structure of production externalities can determine the geographical distribution of workers as economic integration increases. If production externalities are governed solely by geographical distance, a mono-centric spatial distribution emerges in the form of suburbanization. However, if geographically distant pairs of regions are connected through tight production linkages, multi-centric spatial distribution can be sustainable.
