Abstract:

China's soybean import has the characteristics of large overall scale and concentrated import countries. Under the background of greater uncertainty in the current economic and trade environment, China's soybean import supply chain is facing greater pressure. In order to ensure the security of soybean supply in China and deal with the possible external crisis in time, this paper measures the node resilience and structure resilience of global soybean trade network and China's soybean import trade network from 1996 to 2022. The results show that the resilience of China's soybean imports is highly dependent on countries with high-outdegree (e.g., the United States, Brazil) and key intermediate countries (e.g., the United States, Canada, Turkey). When countries in the Northern Hemisphere reduce their soybean exports, Brazil plays a central role in balancing supply and restoring network operations. The role of other countries in the Southern Hemisphere needs to be further developed. Based on this, China should sign long-term purchase and sale agreements with Brazil, establish a joint agricultural fund, and strengthen the mechanism for binding interests with the United States, etc., in order to ensure the stability of China's soybean import supply. China should sign trade agreements with Paraguay, Argentina and other countries, optimize the transportation network, cultivate high-yield soybean varieties, and promote regional cooperation alliances, etc., in order to diversify the supply system in South America. China should sign bilateral agreements with intermediate countries, establish regional supply buffers, and invest in modern logistics facilities, etc., in order to enhance the resilience and risk response capabilities of the soybean supply chain.

Key words: soybean trade, network resilience, capability of destruction-resistance, capacity of recovery, food security

摘要:

中国大豆进口具有总体规模大、进口来源国集中等特点。在当前经贸环境具有较大不确定性的背景下,中国大豆进口供应链面临较大压力。为及时应对可能发生的外部危机,保证中国大豆的供应安全,本研究测度了1996—2022年全球大豆贸易网络和中国大豆进口贸易网络的韧性。结果表明:①中国大豆进口的韧性高度依赖出度较高的国家(如美国、巴西)和关键中间国家(如美国、加拿大、土耳其);②当北半球国家减少大豆出口时,巴西在平衡供应和恢复网络运行中发挥核心作用,而其他南半球国家的作用有待进一步挖掘。基于此,中国可以通过与巴西签署长期购销协议、建立联合农业基金、与美国加强利益绑定机制等方式,确保中国大豆进口供应的稳定性;通过与巴拉圭、阿根廷等国签署贸易协议、优化运输网络、培育高产大豆品种以及推动区域性合作联盟等方式,多元化南美洲的供应体系;通过与中间国家签署双边协议、建立区域供应缓冲区以及投资现代化物流设施等方式,增强大豆供应链的韧性和风险应对能力。
