Research on the risk of marine transportation channel for imported soybeans in China

To ensure the safety of China's grain import sea transportation, the risks affecting China's grain import marine transportation channel are divided into channel condition factors, political environment factors, economic and trade environment factors, and military environment factors, and a risk evaluation index system for China's imported grain marine transportation channels is constructed. After weighting the indicators through the improved CRITIC method based on the entropy weight method, using the principle of system dynamics, considering the COVID-19 and Sino-US trade friction as exogenous factors, a risk assessment model of China's soybean import marine transportation channel is constructed. The risk of China's imported soybean sea channel was simulated, and the risk level of each marine transportation channel for China's soybean import was analyzed and a short-term forecast was made. Finally, the corresponding countermeasures and suggestions are put forward according to the simulation results affecting the risk level of the channel.
