全球水产品贸易网络韧性分析OA

Aquatic products trade is not only a matter of food security,but also an important driver of economic development.This paper selects three major categories of fish,crustaceans and molluscs as the main aquatic products,and constructs a global aquatic products trade network based on data from 2005 to 2023,and analyzes the resilience of the three categories of aquatic products trade network in an in-depth comparative manner.The research findings indicate that the fish trade network exhibits strong agglomeration and transmission properties,with low hierarchical structure,and all three types of aquatic product trade networks are assortative networks.The United States occupies an important position in the global aquatic product trade network,while China's position in global aquatic product trade has significantly improved.Through shock simulation,it is found that deterministic perturbation strategies have a greater impact on network efficiency than stochastic perturbation strategies,and the resilience of the fish trade network is stronger than that of the crustacean and mollusk trade networks.Finally,based on the resilience characteristics of the global aquatic product trade network,it is recommended to increase product technology investment,enhance innovation capabilities,strengthen trade cooperation,conduct risk assessments,and develop contingency plans.Finally,based on the resilience characteristics of the global aquatic products trade network,some policy recommendations are put forward that can help to enhance the stability and risk-resistance of China's aquatic products trade,and strengthen China's competitiveness in global aquatic products trade.
