The onset of the COVID-19 pandemic has accelerated the growth of e-commerce and home deliveries. Automated parcel lockers are a way to improve delivery efficiency, but despite their rapid growth, little is known about their accessibility and equity impacts. Among e-commerce players in the U.S., Amazon stands out by its large market share. This research studies the location of Amazon lockers in Portland, Oregon utilizing highway, land use, employment, and sociodemographic datasets. Geographical tools and cluster analysis are utilized to estimate accessibility and equity metrics. Lockers tend to be located in mixed-use areas and can be utilized by a large percentage of the population. However, the equity metrics indicate that the current distribution of lockers could be improved to reach traditionally underserved populations. Given the environmental and economic advantages of lockers, policymakers should encourage the expansion of this type of last mile solution to avoid market failures in areas that are currently underserved.

COVID-19 大流行的爆发加速了电子商务和送货上门的增长。自动包裹储物柜是提高递送效率的一种方式，但尽管它们发展迅速，但人们对其可及性和公平性影响知之甚少。在美国的电子商务公司中，亚马逊以其巨大的市场份额脱颖而出。本研究利用高速公路、土地使用、就业和社会人口数据集研究俄勒冈州波特兰市亚马逊储物柜的位置。地理工具和聚类分析用于估计可达性和公平指标。储物柜往往位于混合用途区域，并且可供大部分人口使用。然而，公平指标表明，目前的储物柜分布可以改善，以覆盖传统上服务不足的人群。
