摘要
基于2001-2021年数据的实证分析表明,东亚地区的贸易竞争力持续增强,在国际贸易网络当中的地位越来越重要.无论是在"去中心化"的全球贸易网络还是在"中心化"的ICT贸易网络,东亚地区都处于网络结构洞位置,能够对网络的其他节点施加重要影响,地区贸易发展的外溢效应明显.但是,东亚地区加权点出度与点入度差距扩大,贸易网络子群不够稳定,供应链脆弱性增大,以及近年来国际贸易争端突现,都导致了贸易网络发展面临的不确定性增大.另外,多层贸易网络之间存在显著的、非对称的交互响应,而且这种交互响应的扩散过程有可能因为时滞效应而被延长.当各种效应叠加在一起时,贸易网络发展的不确定性将会进一步增大.
Abstract
Based on the empirical analysis of data from 2001 to 2021,it is evident that the trade competitiveness of the East Asian region has continued to rise,and its importance in the international trade network is increasingly important.Whether in the"decentralized"global trade network or in the"centralized"ICT trade network,the East Asian region occupies the position of network structure holes with obvious spillover effects in the regional trade development,exerting a significant influence on other nodes.However,the widening gap between weighted outdegree and indegree in East Asia,the instability of trade network subgroups,the increased vulnerability of supply chains,and the emergence of international trade disputes in recent years have all contributed to the increased uncertainty in the development of the trade network.Additionally,there are significant asymmetric interactions between multiple layers of the trade network,and the diffusion process of these interactions may be prolonged due to time lag effects.When these various effects are combined,the uncertainty in the development of the trade network can further increase.
