全球手机贸易网络演化特征研究

Research on evolution characteristics of global mobile phone trade network

基于复杂网络方法,运用Pajek、Ucinet、Gephi等软件,构建全球手机贸易网络,探究2001～2016年全球手机贸易网络结构及其演化过程。研究发现全球手机贸易极化现象较为严重,贸易活动主要发生在少数国家或地区。随着网络节点的增加和联系的增强,贸易网络呈现稠密化发展,网络整体复杂性开始涌现。全球手机贸易网络核心从欧美向东亚转移,逐渐形成三足鼎立的空间格局,贸易关联的马太效应明显。全球手机贸易子群结构板块特征清晰,美国、加拿大、中国等国家双向溢出角色明显,网络不均衡特征较为显著。

Based on the complex network method,using Pajek,Ucinet,Gephi and other software,the global mobile phone trade network is constructed,and the global mobile phone trade network structure and its evolution process from 2001 to 2016 are explored.The research finds that the global mobile phone trade polarization is serious,and trade activities mainly occur in a few countries or regions.With the increase of network nodes and the enhancement of links,the trade network presents a dense development,and the overall complexity of the network begins to emerge.The core of global mobile phone trade network has shifted from Europe and the United States to East Asia,gradually forming a three-legged spatial pattern,and the Matthew effect of trade links is obvious.The sub-group structure of global mobile phone trade has clear characteristics.The two-way spillover roles of the United States,Canada,China and other countries are obvious,and the network imbalance characteristics are more significant.
