摘要
基于复杂网络理论,从共生演化视角出发建立2002—2019年全球136个国家/地区的进出口贸易流网络矩阵,运用社会网络分析法对区域贸易协定对全球贸易流的影响进行了实证研究。研究发现:①由于择优依附机制的存在,全球贸易格局服从经典的幂律分布,由“平头”走向“陡尾”,产生小世界网络的群聚现象;②全球贸易网络结构从2002年以美、德为首的两大阵营向中、美、德三大国际级社团演化。同配效应推动着边缘国家和地区走向“抱团取暖”,继而通过“择优依附”逐步融入核心国家,推动全球贸易向更加具有开放性的局部世界演化;③政府间贸易协定作为政府“看得见的手”可以解释全球贸易网络结构变动的19.2%,说明国家间协同合作对于推动世界贸易体系发展具有积极影响;④由于网络外部性的影响,多边贸易协定对于贸易的促进作用大于双边贸易协定。鉴于区域化贸易在疫情后各国加强制造业回流时会更加明显,各国政府之间签订多边贸易协定更符合经济复苏和人类命运共同体的大势。
This research explores the impacts of regional trade agreements on global trade flows from the perspective of symbiotic evolution.By using network analysis method on 18 years of two-ways(including import and export)of trade flow network matrixes of 136 countries/regions of the world from 2002 to 2019,the study finds that:1)Due to the mechanism of the preferential attachment,the global trade pattern obeys the classic law of power distribution,moving from"flat head"to"steep tail"from 2002 to 2019,which results in the clustering phenomenon of small world networks.2)The structure of the global trade network has evolved from the dual pillars led respectively by the U.S.and Germany in 2002 to the tripartite forces of China,the U.S.,and Germany.The matching effect drives many peripheral countries and regions to"unite together"and then gradually integrate into the three forces through"preferential attachment",promoting the global trade flow entering a more open world.3)Intergovernmental trade agreements,as the"visible hand"of governments,can explain 19.2%of changes in the global trade,which indicates that collaborative cooperation between countries has positive impacts on the evolution of the world trading system.4)Under the influence of network externalities,multilateral trade agreements demonstrate greater impetus than bilateral trade agreements to global trade.Countries initiating into the multilateral trade agreements conform not only with the general trend of economic recovery after the epidemic,but it is also beneficial to the bright prospect of a community with a shared future for mankind.
