| 摘 要： | 基于稀土产业链视角，通过依赖关系构建稀土初级加工品、中级加工品和制成品贸易网络，运用社会网络分析法和动态指数随机图模型对稀土贸易网络结构演变特征及其影响机制进行对比分析。结果表明：① 3个环节稀土贸易网络均呈现向复杂网络演变的趋势，且稀土中级加工品贸易网络的变化趋势依次领先于稀土制成品和初级加工品贸易网络；② 从主干结构看，3个环节稀土贸易网络依次由欧洲主导向欧美并立演变、由中国主导向欧亚并立演变、由欧美亚三足鼎立向亚洲主导演变；③ 中国在3个环节稀土贸易网络中均发展成为直接影响力前三甲国家（地区），但其领先优势逐渐缩小，而间接影响力仅在初级加工品和制成品网络进入前三甲行列，且增幅较小；④ 互惠、三角形、星形辐射和星形扩张结构效应对3个环节稀土贸易网络动态演变具有显著的异质性影响。

| Abstract: | From the perspective of rare earth industrial chain, this article successively constructed the rare earth primary processed products, intermediate processed products and finished products trade network according to the trade dependence, and empirical test on the dynamic change of rare earth trade network structure and its influencing mechanism by using social network analysis method and Temporal Exponential Random Graph Model. The following conclusions are drawn. The three types of rare earth trade network are evolving into a complex network, and the trend of the intermediate processed products goods network ahead of the finished products and primary processed goods network in turn. From the perspective of backbone structure, three types of rare earth trade network have evolved from Europe to Europe and the United States, from China to Europe and the United States, and from Europe, the United States and Asia to Asia. China evolves into the top three countries with direct influence in all networks, but its leading edge has gradually narrowed, while its indirect influence has only entered the top three countries in the network of primary processed products and finished products, with a small increase. Mutual, triangle, star-radiation and star-expansion structure effects have significant heterogeneous effects on the dynamic evolution of the three types of rare earth trade network. |
