“一带一路”沿线国家铁矿石贸易的空间结构及影响因素研究

Research on the spatial structure and influencing factors of iron ore trade in “the Belt and Road” countries

“一带一路”沿线国家铁矿石贸易对经济建设发展有重要作用,明晰铁矿石贸易格局对我国钢铁产业发展具有指导意义。本文基于UN Comtrade数据库2008~2017年的贸易数据,采用社会网络分析方法(SNA)分析了“一带一路”沿线60个国家铁矿石贸易的空间结构及影响因素。结果表明:铁矿石贸易网络密度较低,中国、俄罗斯、乌克兰和印度是贸易网络的稳定中心节点;在2017年的贸易网络中,中国、土耳其等国家起到了传递网络信息的桥梁作用,俄罗斯、印度、乌克兰等国家主导整个网络走向;铁矿石贸易网络的主要影响因素包括国家间陆地相邻、共同文化背景、制度差异程度,而与国家间地理距离、经济发展差异相关性不大。

Iron ore trade in countries along the“the Belt and Road”line plays an important role in economic construction and development.Based on the trade data of UN Comtrade database from 2008 to 2017,the spatial structure and influencing factors of iron ore trade among 60 countries along“the Belt and Road”route are analyzed by social network analysis method(SNA).The results show that the density of iron ore trade network is low.China,Russia,Ukraine and India are the stable nodes of the trade network.In the trade network of 2017,China,Turkey and other countries serve as a bridge to transmit network information,while Russia,Ukraine,India and other countries dominate the whole network trend.The main influencing factors of iron ore trade network are land proximity,common cultural background and institutional differences among countries,but there is little correlation with geographical distance and economic development differences among countries.
