摘　　要：文章收集了"一带一路"沿线65个国家的双边贸易数据,构建了经贸物流网络;通过UCINET软件计算了网络密度、度数等网络结构特征参数;通过平均最短路径长度、簇系数、度分布研究了经贸物流网络的"小世界"性质;通过中心性、核心—边缘分析,对网络中的核心节点进行了研究。结果表明:"一带一路"国家的经贸物流网络同时具有"小世界"与"无标度"双重属性;节点间具有较强的关联性;可利用核心度指标将65个沿线国家分为核心节点、准核心节点和边缘节点三类,采取不同的措施实现促进国际贸易协同发展。This paper collects 65 countries’ bilateral trade data along the belt and road, and builds logistics and trade network. The network structure characteristic parameters such as network density, degree are calculated and compared by UCINET software. This paper studies the" small-world" and"scale-free"properties of logistics and trade network through the average shortest path length, cluster coefficient and degree distribution. Through centrality and core-periphery analysis,the core nodes in the network are studied. The results show that logistics and trade network has" small world and scale free" characteristics. There is a strong correlation between nodes. The core index can be used to divide the 65 countries along the line into three categories: core node, quasi core node and edge node, and take different measures to promote the coordinated development of international trade.
