中日韩参与增加值贸易合作比较——基于复杂网络方法

China,Japan and South Korea's Participation in Value-added Trade Cooperation:Comparison Based on Complex Network Methods

东亚是全球增加值贸易合作网络的重要区域,中日韩作为该区域的主要节点国家,在全球及区域增加值贸易合作中的地位存在差异。借助复杂网络节点“中心性”测算方法,从国家层面比较了中日韩三国在全球以及东盟“10+3”增加值贸易网络里的中心地位。研究发现,中国和日本是全球及区域增加值的主要供给国,而韩国是主要需求国,且中国的总体中心地位明显提高。中国对外应积极参与中日韩及其他区域经济合作,对内支持企业自主创新、加强生产性服务业和制造业深度融合。

East Asia is an important region of the global value-added trade cooperation network.As the major node countries in the region,China,Japan,and South Korea position differently in global and regional value-added trade cooperation.This paper compares the centrality of China,Japan,and South Korea in the global and ASEAN+3 value-added trade networks by using the measures of"centrality"of nodes in complex networks.It is found that China and Japan are the main suppliers in the global and regional value-added trade networks while South Korea is the main demand country,and China's overall central position has improved significantly.China should actively participate in regional economic cooperations,support domestic enterprises'independent innovation,and strengthen the deep integration of productive services and manufacturing.
