| 摘 要： | 为了考察战略性关键金属贸易网络特征对产业结构升级的影响,本文基于复杂网络分析方法,以1996—2017年7种战略性关键金属贸易数据为基础,定量刻画了全球战略性关键金属贸易网络的拓扑特征,并从入度中心度、出度中心度、接近中心度、中间中心度和特征向量中心度,5个维度全新解构各国在贸易网络中的角色和地位,以此并构建面板回归模型,实证分析贸易网络特征对产业结构升级的影响。研究结果表明：①1996—2017年期间全球战略性关键金属贸易网络具有松散性和异质性,并呈现“小世界”特征;②就个体而言,中国、美国和德国是全球战略性关键金属贸易的重要参与者,在贸易网络中占据中心地位;③接近中心度和中间中心度对一国产业结构升级具有显著的促进作用,且这种影响在低收入国家表现更为突出,而出入度和特征向量中心度的影响则不显著。中国应采取更加开放的贸易政策,并提升在全球价值链中的分工地位,促进产业结构优化升级。 |

| Abstract: | In order to investigate the impact of strategic and critical metals trade network characteristics on the upgrading of industrial structures, we quantitatively characterized the topological characteristics of the network based on complex network analysis methods, using the trade data of the seven strategic and critical metals from 1996 to 2017. This study measured the degree of centrality from five dimensions: in-degree centrality, out-degree centrality, closeness centrality, betweenness centrality, and eigenvector centrality. We deciphered the roles and positions of countries in the trade network. Based on these, this study further constructed a panel regression model to examine how the characteristics of strategic and critical metals trade network impact the industrial structure upgrading. The research results show that: (1) The global strategic and critical metals trade network is loose and heterogeneous during 1996-2017 and shows the characteristics of a “small world”. (2) Individually, China, the United States, and Germany were important participants in global strategic and critical metals trade, occupying a central position in the trade network. (3) Further research found that closeness centrality and betweenness centrality showed a significant effect on promoting the upgrading of a country’s industrial structure. This effect was more prominent in low-income countries. But the influence of in-degree centrality, out-degree centrality, and eigenvector centrality were not obvious. China should adopt a more open trade policy and enhance its position in the division of labor in the global value chain to promote the optimization and upgrading of its industrial structure. |
