Abstract:

Facing the structural contradiction of fluctuations in the global soybean supply chain and China's import dependence, this research is based on the data of the United Nations Trade Statistics Database (UN Comtrade) from 2000 to 2023, and uses the Social Network Analysis (SNA) method to deconstruct the network topology structure. Reveal the role positioning and evolution laws of China. Main research results show that: ① The scale of the global soybean trade network continues to expand, and the closeness between nodes is getting stronger and stronger, presenting a "core-edge" structural feature. North and South America (Brazil, the United States) and Asia (China, Japan) form "production-consumption" dual core, while Europe, with its port hubs (the Netherlands, Belgium), becomes a transshipment node across continents. ② China's weighted import centrality has consistently ranked first, but its imports are highly concentrated in Brazil and the United States. Its betweenness centrality ranks fifth, and its pricing power is weaker than that of the United States. Brazil's weighted out-degree centrality has risen to the top globally, while the United States has dropped to the second place. ③ The trade network density of core countries reached 0.522, with an average path length of 1.469, presenting a highly interconnected feature. The Sino-US trade war in 2018 accelerated the diversification of China's import sources, but did not fundamentally change the risk of "path dependence" in the supply chain. The research provides a comprehensive path of "network optimization-institutional innovation-technological empowerment" to solve the predicament of "scale dependence-power deficiency" in China's soybean industry, and helps implement the food security strategy.

摘要:

面对全球大豆供应链波动与中国进口依赖的结构性矛盾,本研究基于联合国贸易统计数据库(UN Comtrade) 2000—2023年数据,运用社会网络分析方法构建加权有向网络模型,从网络密度、中心性、“核心-边缘”结构等维度,系统揭示全球大豆贸易网络的演化规律和中国在其中的角色定位。主要发现如下:①全球大豆贸易网络规模持续扩张,节点之间的联系愈来愈紧密,呈现明显的“核心-边缘”结构特征,美洲(巴西、美国)与亚洲(中国、日本)形成“生产-消费”双核心,欧洲凭借港口枢纽(荷兰、比利时)成为跨洲中转节点。②中国加权入度中心度持续居首,但进口高度集中于巴西、美国,且中介中心性排名第五位,表明其定价权弱于美国;巴西加权出度中心度跃居全球第一,美国降至第二位。③核心国家贸易网络密度达0.522,平均路径长度为1.469,呈现高度互联的网络特征;2018年中美贸易战加速中国进口来源多元化,但未根本消除供应链“路径依赖”带来的风险。本研究为破解中国大豆“规模依赖-权力缺失”的突出困境,提供“网络优化-制度创新-技术赋能”的综合路径,助力粮食安全战略有效实施。
