全球数字贸易中的竞争互补关系及其演化--基于社会网络分析方法

Competitive and Complementary Relationship in Global Digital Trade and its Evolution:Based on Social Network Analysis Method

文章运用社会网络分析法研究全球数字贸易中各经济体间的竞争互补关系及其演化,发现:全球数字贸易中各经济体间的竞争性和互补性逐年提升,但互补性大于竞争性;俄罗斯和波兰等经济体具有较高的竞争性,法国和加拿大等经济体具有较高的互补性;中国的竞争性快速提升,且提升速度快于互补性;当前,全球数字贸易中存在三大竞争关系板块及两大互补关系板块。以美、英、加为首的板块1和以中、德为首的板块2在板块内及板块间都存在激烈竞争。以越、印为首的板块3仅在板块内存在激烈竞争。两大互补关系板块一个由美、英、印等经济体组成,该板块对内对外都存在紧密的互补关系;另一个板块由中、加、越等经济体组成,该板块仅对外存在紧密的互补关系。

By using social network analysis method,this paper studies the competitive and complementary relationship among the economies in global digital trade and its evolution,and finds that the competitiveness and complementarity among the economies in global digital trade are increasing year by year,but the complementarity is stronger than the competitiveness;the economies such as Russia and Poland are highly competitive,while the economies such as France and Canada are highly complementary;China’s competitiveness increases rapidly and the improvement of competitiveness is faster than that of complementarity.In addition,there are three competitive sectors and two complementary sectors in global digital trade at present.Fierce competition exists not only within the cluster 1 led by the United States,the United Kingdom and Canada as well as the cluster 2 led by China and Germany,but also between these two clusters.The cluster 3 led by Vietnam and India only has a fierce competition within the cluster.One of the two complementary clusters consists of the economies including the United States,the United Kingdom,India,etc.It has a close complementary relationship internally and externally.The other cluster consists of the economies including China,Canada,Vietnam,etc.It only has a close complementary relationship externally.
