摘　　要：文章基于2005~2015年金砖国家排名前25的贸易伙伴的双边贸易数据,采用网络分析法探讨了金砖国家贸易网络结构特征的演化。从密度、网络中心性、网络联系强度以及聚类系数等指标对贸易网络结构的总体属性和节点属性演变进行分析,研究发现贸易网络属性是一个循序渐进的演化过程,金砖国家贸易网络在一定程度上遵循幂律分布,且呈现出层次性结构特征。在此基础上进一步检验了贸易网络特征对金砖国家贸易分工地位的影响,结果显示网络中心性、网络联系强度以及聚类系数对其贸易分工地位有显著的正向影响。Based on the bilateral trade data of the top 25 trading partners of BRICS, this paper discusses the evolution of the characteristics of BRICS＇ trade network structure in 2005-2015 based on the analytic network process. We analyze the topology evolution, including both the trade network structure and node attributes from the perspectives of the density, degree, strength, clustering coefficient and some other network statistics. The results show that the evolution of trade network properties experiences a gradual process and the trade network of BRICS follows the power-law distribution in a certain extent with a hierarchical structure. On that basis, we examine the impact of trade network characteristics on BRICS＇ trade division position. The result shows that the network centrality, strength and clustering coefficient have a significantly positive impact on the trade division position.
