摘 要:农产品贸易是实现全球“0”饥饿可持续发展目标的重要渠道,在世界变局的加速演进阶段,急需展开贸易网络布局及节点国家影响力的研究。基于复杂网络理论研究农产品贸易的演化,通过网络效率测度一国影响力。结果表明:1)农产品贸易网络日趋高效、紧密。2)节点国家影响力与其综合实力密切相关;影响力大的国家进出口强度大,而且一国出口强度与进口强度存在正相关。3)农产品贸易主要由少数几个大国主导,在自然灾害或地缘政治等不稳定性因素下,会加剧全球农产品供给的脆弱性。Agricultural product trade is an important channel to achieve the global"zero"hunger sustainable development goal.In the accelerated evolution stage of world changes,there is an urgent need to conduct research on the layout of trade networks and the influence of node countries.This article studies the evolution of agricultural product trade based on complex network theory and measures a country's influence through network efficiency.The results show that:1)The agricultural product trade network is becoming increasingly efficient and close.2)The influence of a node country is closely related to its comprehensive strength;countries with great influence have strong import and export intensity,and there is a positive correlation between a country's export intensity and its import intensity.3)Agricultural product trade is mainly dominated by a few large countries,which will exacerbate the vulnerability of global agricultural product supply under unstable factors such as natural disasters or geopolitics.
