基于社会网络分析的稀土永磁贸易国际格局研究

Research on International Pattern of Rare Earth Permanent Magnet Trade Based on Social Network Analysis

通过对比“一带一路”倡议实施前后贸易格局的改变,可以直观地看到倡议所带来的影响及存在的不足。采用社会网络分析法对2012年和2017年稀土永磁材料的贸易数据进行中心性和核心-边缘结构等分析。研究发现,稀土永磁国际贸易的核心-边缘结构弱化,单个国家的影响力呈下降趋势,国家间永磁贸易关系稳健性提高。但倡议的实施依然存在阻力,中国仍需加强同欧洲国家的联系,同时做好“一带一路”物流服务,并着力培育高技术人才促进中国稀土永磁产业向纵深发展。

There are a few literatures upon changes of international trade pattern in rare earth permanent magnet since The Belt and Road Initiative has been presented.Visualized advantages and disadvantages of the initiative can be observed through changes brought by the initiative.The paper used social network analysis method to analyze the central and core-edge structure with international trade data of permanent magnet materials in 2012 and 2017.The results show that the core-edge structure is fading,the influence of single nation is declining,and the relationship among permanent magnet trade countries is more stable.However,there are still resistances in the implementation of the initiative.It means China needs to build a more stable relationship with European countries,offer better logistics services,and push for in-depth development of China*s rare earth permanent magnet by cultivating high-tech personnel.
