摘　　要：Global supply chain networks foster collaboration but accelerate cross-border risk transmission.This study investigates the effect of the 2011 East Japan earthquake on Chinese firms'import strategies.The findings reveal that the disruption led to a shift toward supply chain concentration,with firms reducing the diversification of import sources.There was a slight increase in the number of countries from which firms sourced imports but import shares became more concentrated,reflecting a reliance on fewer,centralized suppliers.Firms affected by the earthquake prioritized long-term partnerships and sought suppliers in regions with lower natural disaster risks,aiming to mitigate supply chain vulnerabilities and reduce switching costs.The findings also show that state-owned enterprises,private firms,and research and development-intensive firms were more inclined to centralize their import sources.This suggests that these firms,leveraging their larger scale,substantial resources,and robust risk management strategies,favored a more concentrated sourcing approach in order to better control their supply chains and ensure stability in the face of global disruptions.
