中国与“一带一路”沿线国家贸易网络解析

Trading Network Between China and the Countries Involved in the Belt and Road

“一带一路”倡议的提出,促进了中国与沿线国家的进出口贸易。基于2007-2018年中国与“一带一路”沿线国家多边贸易数据,使用社会网络分析法探究中国与“一带一路”沿线国家贸易网络结构及其动态变化。研究发现:中国与“一带一路”沿线国家贸易联系非常紧密,贸易网络中越来越多的经济体之间产生新的贸易联系,网络结构具有较强的稳健性;贸易网络呈现核心-半边缘-边缘的结构特征,经济发展水平相对较高的国家位于网络中心,起到关键的联通与桥梁作用;中国在该网络中的绝对核心地位不断攀升,逐渐形成以中国为核心的世界贸易格局;越南的核心度逐年递增,由边缘区上升至核心区。

The Belt and Road(B&R)initiative promotes the import and export trade between China and countries along it.Based on the trade data between China and countries along the Belt and Road from 2007 to 2018,the article applies the social network methodology to investigate the trading network structure and its dynamic changes between China and these countries.The research finds:China has closely trade relations with these countries,new trade relations emerge among more and more economic units in the trading network and the trading network seems to be very stable;the trading network displays a structural nature of“core-semi peripheral-peripheral”,among which countries with relatively advanced levels of economic development enjoy certain degrees of centrality and play critical roles of bridge and connection;China’s role in this trading network keeps expanding and a China-centred global trading network has gradually been formed;Vietnam’s role is also elevating and moving from a peripheral status to a core status.
