摘　　要：“冰上丝绸之路”倡议为沿线国家贸易发展提供了机遇,可加速经济要素跨国流动,促进全球贸易的可持续发展。基于2019年37个“冰上丝绸之路”沿线国家贸易数据,运用复杂网络分析方法,研究37个“冰上丝绸之路”沿线国家贸易网络的拓扑结构特征、贸易社团及节点中心性的地理空间分布特征。结果表明:1)贸易网络具有良好的互通性和扩散性,且具有小世界特征和无标度性质,两极分化较为显著;2)贸易网络呈现出明显的“核心—边缘”圈层结构特征,德国、中国、美国、荷兰处于核心圈层,是贸易网络的枢纽;3)贸易网络可划分为1个北美社团、1个以东亚国家为主的社团和3个以欧洲国家为主的社团,其空间分布表现出连续性特征,各社团内部贸易联系密切,中国是所属社团的核心;4)贸易网络呈现出枢纽辐射式和全连通式共存的结构,强度中心性呈嵌入式的单元格局,接近中心性呈集中连片区块状分布特征,中介中心性的极化现象较为明显。As an extension of the Belt and Road Initiative to the Arctic,the Polar Silk Road initiative has provided opportunities for international trade development along its routes.this can accelerate the transnational flow of economic factors and promote the sustainable development of global trade.Based on the trade data of 37 countries along the Polar Silk Road in 2019,a trade network of these countries has been constructed.The complex network analysis method is used to study the topological structure characteristics of the trade network and to analyze the geo-spatial distribution characteristics of the three centrality indexes of the nodes.Community detection is used to identify the structure of the trade community and analyze its spatial distribution characteristics.With the help of the Continuous Coreness model,the core degree of the country is calculated and its circle structure is visualized.This study found that:(1)The high density and reciprocity of the trade network indicate that the network is very interoperable and diffusive.Compared with the random network,the Polar Silk Road trade network has a higher agglomeration coefficient and a shorter average path length,indicating that it has the characteristics of small-world and scale-free.(2)The trade network node has a typical hierarchy,presenting obvious characteristics of the"core-edge"circle structure,while Germany,China,the United States,and the Netherlands are in the core circle and are the hubs of the trade network.(3)The trade network can be divided into five different communities,namely the North American community,a community dominated by East Asian countries,and three communities dominated by European countries.Their spatial distribution is characterized by continuity,with close trade links among the communities,and China is the core of the community to which it belongs.(4)The trade network is characterized by the coexistence structure of hub radiation and full connection.The intensity centrality presents an embedded unit pattern,and the closeness centr
