Agglomeration economies’ influence on logistics clusters’ growth and competitiveness
研究识别了美国物流集群，并利用邮政编码级数据分析集聚经济对物流企业数量和就业增长的影响，发现高度本地化的集聚经济能促进企业数量增长，但效果随空间距离迅速减弱。
Agglomeration economies’ influence on logistics clusters’ growth and competitiveness. Regional Studies. This study identifies logistics clusters and explores their effect on establishment and employment growth to extrapolate the presence of competitiveness-enhancing agglomeration economies in clusters. The study uses a US ZIP code-level dataset to enhance past research by increasing spatial precision and statistically controlling for related variables. There is some evidence of disproportionate growth in the number of logistics establishments in clusters due to highly localized agglomeration economies, which appear to degrade quickly over space. However, the results are mixed, calling for research into the mechanisms purported to produce agglomeration economies in logistics clusters.
