数字基础设施建设与发展中国家绿色产品出口

Digital Infrastructure Construction and Green Product Export of Developing Countries

文章利用2008~2019年42个发展中国家出口贸易数据,考察发展中国家数字基础设施建设对绿色产品出口的影响。研究发现,发展中国家数字基础设施建设显著促进了绿色产品出口,并且这种促进作用背后的逻辑在于降低信息成本和推动产业绿色化转型。异质性分析表明,在环境约束力度、知识产权保护强度较高的国家,数字基础设施的促进作用更大;当进口目的地为发达国家(地区)时,数字基础设施的促进作用更大;数字基础设施建设对不同生产阶段绿色产品出口的影响存在差异。进一步基于“宽带中国”试点政策的检验表明数字基础设施建设显著促进中国绿色产品出口,为基本结论提供了外生证据支持。在全球数字化转型浪潮下,文章的研究为发展中国家提高绿色国际竞争力提供一定的思路。

Using the export trade data of42developing countries from2008to2019,this paper examines the impact of digital infrastructure construction on developing countries′green product exports.Results show that digital infrastructure significantly promotes the export of developing countries′green products,and the logic behind this promotion lies in reducing information costs and promoting green transformation of industries.Heterogeneity analysis shows that in countries with higher environmental constraints and intellectual property protection intensity,the role of digital infrastructure is greater;when the import destination is developed countries or regions,digital infrastructure plays a greater role in promoting green product exports;the impact of digital infrastructure construction on the export of green products at different production stages is different.Further tests based on the"broadband China"pilot policy show that digital infrastructure significantly promotes the export of China′s green products.Under the tide of global digital transformation,this paper provides some enlightenments for developing countries to improve their green international competitiveness.
