Abstract This paper evaluates whether or not there is a sprawling tendency to the spatial patterns of warehouse establishments in the Chicago and Phoenix metropolitan areas. The trend of warehouses to move away from the urban centers to more suburban and exurban areas is referred to as “Logistics Sprawl”. To measure sprawl, the barycenter of warehousing establishments was compared to the barycenter of all other industry establishments in the region between the years of 1998 and 2013 for Chicago; 1998 and 2015 for Phoenix. This shows that logistics sprawl is a behavior experienced by warehouses in the Chicago area, but not in the Phoenix area. This paper discusses if logistics sprawl is a national trend or a regional behavior by comparing these results to the previous case studies of the Atlanta, Los Angeles, and Seattle metropolitan areas.

对芝加哥和凤凰城物流蔓延的评估

摘要 本文评估了芝加哥和凤凰城都市区仓库设施的空间格局是否存在蔓延趋势。仓库从城市中心转移到更多郊区和远郊地区的趋势被称为“物流蔓延”。为衡量蔓延程度，将 1998 年至 2013 年芝加哥仓储设施的重心与该地区所有其他工业设施的重心进行了比较；1998 年和 2015 年为凤凰城效力。这表明物流蔓延是芝加哥地区仓库所经历的行为，而凤凰地区则不然。本文通过将这些结果与之前对亚特兰大、洛杉矶和西雅图大都市区的案例研究进行比较，讨论物流蔓延是全国趋势还是区域行为。
