This study conducted a social network analysis of the evolutionary characteristics of the world dairy trade network based on the overall trade pattern. In addition, the evolution of trade blocs and the co-opetition relationships involving dairy products in major countries were analyzed in terms of supply and demand. The results show that continuous and complex changes have taken place in the world's dairy trade network since 2001. The number of trade entities in dairy products has stabilized since 2012. At present, approximately 94% of countries (regions) are involved in dairy product trade, such that the world dairy trade network exhibits the small-world effect and scale-free property. The world import pattern for dairy products has changed. While export centers have not changed, import centers have shifted from Europe, America, and East Asia to North America, East Asia, and the Middle East. The world dairy trade network consists of the EU trade bloc headed by Germany, the former Soviet Union-Brazil trade bloc, and the Asia-Australia-America trade bloc. The trade blocs have evolved due to geographical positions, historical cultures, and political relations. In a trade bloc, the diversification of import sources is more prominent in demand countries. European and Asian markets have become the main markets of the major exporters. In this study, the evolutionary characteristics of the world dairy trade network and the co-opetition relationships were analyzed to provide scientific support to inform the development of dairy trade policies. The results can provide technical and psychological support to policy-makers in various countries in their dairy trade decision-making.
本研究基于全球乳业贸易格局,对世界乳业贸易网络的演化特征进行了社会网络分析。此外,从供需角度分析了贸易集团的演变以及主要国家乳制品的竞合关系。结果表明,2001年以来世界乳业贸易网络发生了持续而复杂的变化。自2012年以来,乳制品贸易实体数量趋于稳定。目前,约94%的国家(地区)参与乳制品贸易,世界乳业贸易网络呈现出小世界效应和无标度特性。世界乳制品进口格局发生了变化。虽然出口中心未变,但进口中心已从欧美和东亚转移至北美、东亚和中东。世界乳业贸易网络由德国为首的欧盟贸易集团、前苏联-巴西贸易集团以及亚洲-澳大利亚-美洲贸易集团构成。贸易集团因地理位置、历史文化和政治关系而演变。在一个贸易集团中,需求国进口来源的多元化更为突出。欧洲和亚洲市场已成为主要出口国的主要市场。本研究分析了世界乳业贸易网络的演化特征和竞合关系,为乳业贸易政策的制定提供科学依据。研究结果可为各国政策制定者在乳业贸易决策中提供技术和心理支持。
