摘　　要：本文基于2015—2019年长三角地区四个省份与全球159个国家的出口数据,通过构建数字基础设施发展水平指标,深入探讨了数字基础设施与出口二元边际之间的关系。本文引入了两个替换变量来验证结果的稳健性。研究表明,数字基础设施的完善不仅对出口扩展边际的增长具有显著促进作用,还推动了出口集约边际的扩张。进一步的异质性分析显示,长三角地区的数字基础设施完善在促进与发展中国家的出口贸易增长方面成效显著,然而,与发达国家的出口贸易合作深度却在一定程度上受到了抑制。基于此,本文提出应加快数字基础设施建设步伐,积极营造数字贸易发展空间。同时,应努力消除与发达国家之间的贸易壁垒,缩小“数字鸿沟”,以推动出口贸易向更高质量的方向发展。Based on the export data of four provinces in the Yangtze River Delta region and 159 countries around the world from 2015 to 2019,this paper explores the relationship between digital infrastructure and dual margin of export by constructing a development level index for digital infrastructure.Two substitution variables are introduced to verify the robustness of the results.Research shows that the improvement of digital infrastructure not only significantly promotes the growth of export expansion margin,but also pushes forward the expansion of export intensive margin.Further heterogeneity analysis shows that the improvement of digital infrastructure in the Yangtze River Delta has achieved remarkable results in promoting the growth of export trade with developed countries,but the depth of export trade cooperation with developed countries has been restrained to a certain extent.Based on this,this paper proposes to accelerate the construction of digital infrastructure and actively create space for the development of digital trade.At the same time,efforts should be made to eliminate trade barriers with developed countries and narrow the"digital divide",so as to promote the higher-quality development of export trade.
