Logistics clusters can help businesses grow and compete better. A study looked at these clusters in the US and found that they can attract more companies to set up shop in the same area. This growth seems to happen because of the benefits of being close to other logistics businesses, like sharing resources and knowledge. However, these benefits don't spread out very far - they mostly help companies that are very close to each other. Overall, more research is needed to understand exactly how these benefits work in logistics clusters.
