摘要
随着数字技术的广泛应用,数字贸易日益成为重塑全球产业链供应链的重要力量,在全球服务贸易中的主导地位逐步显现。基于2005—2020年存在数字贸易往来的经济体数据,采用社会网络分析方法,探讨全球数字贸易网络整体特征、网络中经济体个体特征以及数字贸易网络格局演变规律,研究发现,全球数字贸易规模在样本期内迅速扩大,各经济体之间的数字贸易联系更加紧密,经济体之间的通达性与聚集程度显著提升,美欧等经济体在交易能力、控制能力、中介作用等方面处于数字贸易网络的核心枢纽地位;采用QAP方法,结合各经济体数字贸易限制指数,剖析全球数字贸易主要治理规范,研究发现,数字贸易发展与数字贸易限制程度负相关;基于行业异质性视角,探究各经济体在数字贸易不同领域网络地位的差异性与演变特征,研究发现,尽管初期各经济体在数字贸易不同领域具有各自的比较优势,但近年来美欧等经济体在数字贸易各领域的优势地位更加明显。为促进我国数字贸易高质量发展,应重视数字技术应用,扩大数字贸易规模;处理好开放与保护的关系,提升我国数字治理能力;把握区域经贸协议扩容机遇,更好融入国际数字贸易;提高金融服务水平,加强知识产权保护。
With the wide application of digital technology,digital trade has become the important forces for us to reshape global industrial chain and supply chain.And the leading role of digital trade in global service trade has gradually emerged.To explore the the relationship between global digital trade network structure and the restriction of digital trade,based on the data of economies involved in digital trade from 2005 to 2020,and using the social network analysis method,the author studies the characteristics of global digital trade network as a whole,the characteristics of individuals in this network,and the evolution rule of the global digital trade network.It is found that:the scale of global digital trade has expanded rapidly in the sample period,the digital trade links among economies have become closer,and the accessibility and agglomeration of economies have also significantly improved;and the United States and some European economies are at the core hub of the digital trade network in terms of transaction ability,control ability and intermediary role.With the help of QAP method,and combined with digital trade restriction index,the author explores the governance norms of global digital trade;it is found that the development of digital trade is negatively correlated with the degree of digital trade restriction.From the perspective of industry heterogeneity,the author explores the differences of every economy’s network position in different fields of digital trade,and the evolution characteristics of that;it is found that,although different economies had their comparative advantages in different digital trade fields at the beginning of the sample period,in recent years,the advantages of the United States and some European economies in various fields of digital trade were more obvious.To improve China’s high-quality development of digital trade,we should,first,pay more attention to the application of digital technology and expand the scale of digital trade;second,we should do a better job in dealing with the
