This study examined the transport network of global marine dry bulk carriers for agricultural trade during the period from 2018 to 2021. Firstly, the resilience of agricultural trade network is noteworthy throughout the COVID-19 pandemic. Agricultural trade initially plunged by 10.15% from 2019 to 2020 and bounced by a remarkable 11.45% in 2021, ultimately restoring trade volumes to the average level observed in the pre-pandemic year of 2019. However, the ports in Brazil and Argentina displayed less resilience in their agricultural trade with a continued decline in agricultural trade quantities in 2021. Additionally, the outbound trips increased in Ukraine, Canada, and Russia and decreased in Brazil and Argentina, leading to a more tightly knit agricultural network since 2020. Overall, this study provided evidence in comprehensively assessing the capacity and resilience of global food supply chains, especially in the context of constantly evolving circumstances and challenges.

全球农产品贸易弹性分析

本研究考察了2018年至2021年期间全球海运干散货船用于农产品贸易的运输网络。首先，农产品贸易网络在整个COVID-19大流行期间的弹性值得注意。2019年至2020年，农产品贸易最初暴跌10.15%，2021年大幅反弹11.45%，最终将贸易量恢复至2019年疫情前的平均水平。然而，巴西和阿根廷港口的恢复能力较差2021年，农产品贸易量继续下降。此外，乌克兰、加拿大和俄罗斯的出境游增加，巴西和阿根廷的出境游减少，导致2020年以来农业网络更加紧密。总体而言，本研究为全面评估全球粮食供应链的能力和复原力提供了证据，特别是在不断变化的情况和挑战的背景下。
