The Impact of Environmental Uncertainty and Operational Flexibility on Delivery Performance: A Natural Experiment
摘 要：
Using data from 506,466 deliveries of orders of 6,608 SKUs, we study the impact of environmental uncertainty on delivery performance across two types of logistics complexity structures: within-city deliveries (low supply chain complexity) and cross-city deliveries (high supply chain complexity). We obtain exogenous variation in the environmental uncertainty through a difference-in-differences model, which exploits the typhoon Lekima event. Focusing on the high supply chain complexity of cross-city deliveries, we study how operational flexibility strategies by regulating throughput efficiency, and buffering through transfer center, can be leveraged when facing supply chain disruption. Since the extent of uncertainty varies as the cycle of typhoons evolves, our identification strategy further supports the insights into the impact of operational flexibility strategies on delivery performance as uncertainty transitions from unknowable unknown, knowable uncertainty, known uncertainty, and known certainty. We provide causal validation by revisiting the relationship between uncertainty and flexibility on performance, which has been neglected; and in turn, strengthen the support for contingency theory on supply chain practice.
