Night delivery is an approach increasingly used by motor carriers to improve the efficiency of business-to-business logistics. Many benefits of night deliveries have been reported in the literature, but in practice, not every carrier is benefitting from night deliveries. In fact, anecdotal evidence suggests that many carriers are losing money from night deliveries. While a limited number of past studies have discussed the disadvantages of night deliveries, in many cases, they cannot explain why carriers are not benefitting from night deliveries. This implies that some disadvantages of night deliveries may still be currently unknown. This paper seeks to identify such “hidden” disadvantages by studying this issue through the lens of transportation economics. Understanding such disadvantages can contribute to both theories and practice of night deliveries, especially for decision making on night-delivery adoption by carriers, as it can lead to a better understanding of when and where night deliveries might be beneficial or detrimental.

通过夜间送货降低 B2B 物流成本：真的有效吗？

夜间送货是越来越多的汽车承运人用来提高企业对企业物流效率的方法。文献中报道了夜间交付的许多好处，但在实践中，并非每个承运人都从夜间交付中受益。事实上，轶事证据表明，许多承运人都因夜间送货而亏损。虽然过去有少量研究讨论了夜间送货的缺点，但在许多情况下，它们无法解释承运人为何无法从夜间送货中受益。这意味着夜间送货的一些缺点目前可能仍然未知。本文试图通过从交通经济学的角度研究这个问题来识别这种“隐藏”的缺点。
