Global supply chain risk assessment and resilience measurement:Taking soybean as an example
Amid the increasing global uncertainties,studying the risk structure and resilience level of global supply chains for agricultural products highlights their importance.It not only provides China with a scientific foundation for better utilizing international markets and resources and ensuring the safety of agricultural product imports,but also promotes the development of risk resilience management theories and methods for typical products across geographical spaces,thus expanding research in resource geography.This study builds a framework that consists of three sectors(export sectors,logistics and transportation sectors,and import sectors)and four stages(supply,procurement,transportation,and demand).Using two-stage DEA and CoDEA models,it evaluates the supply chain risks and resilience of soybeans,which is the typical import-dependent agricultural product in China.The findings indicate that:(1)The risk of China's imported soybean supply chain increased from 2000 to 2020,with risks predominantly from the demand and procurement stages.By contrast,the supply and transport stages are less risky but significantly increased.Trade relations with exporting countries and economic policy uncertainty are the main long-term risk factors that threaten the security of soybean import supply chains.(2)China's soybean supply chain from Brazil is more resilient than that from the US and Argentina,suggesting great potential for improving supply chain cooperation with Brazil.(3)Making the distinction between short-and long-term threats is necessary for managing the risk resilience of the global soybean supply chain.Improving the capacity to react to sudden hazards represented by trade restrictions,maritime obstructions,and trade sanctions should be the priority in the short term.Long-term exploration of system construction and strategic layout optimization is necessary to improve the discursive power of the supply chain.
