“一带一路”沿线国家(地区)数字经济联系程度对贸易密切度影响研究

Research on the influence of the degree of digital economic connectivity on trade closeness of countries(regions)along the Belt and Road

基于国家间数字经济联系程度和贸易密切度指标,利用2013—2021年39个“一带一路”沿线国家(地区)面板数据,实证检验了“一带一路”沿线国家(地区)间数字经济联系程度对其贸易密切度的影响及作用机制,结果表明:“一带一路”沿线国家(地区)间的数字经济联系程度对其贸易密切度具有正向促进效应;“一带一路”沿线国家(地区)的地理距离、文化距离和关税壁垒对国家间的贸易密切度具有显著抑制效应;提升“一带一路”沿线国家(地区)间的数字经济联系程度能够弱化地理距离、文化距离和关税壁垒对贸易密切度的抑制作用;数字经济联系程度提升贸易密切度的作用机制在不同国家间存在区域异质性。为此,要加快“一带一路”沿线国家(地区)数字经济发展,加强各国数字经济联系,提升贸易密切度,推动“一带一路”沿线国家(地区)贸易持续健康发展。

Based on the indicators of the degree of inter-country digital economic connectivity and trade closeness,this paper uses the panel data of 39 countries(regions)along the Belt and Road from 2013 to 2021 to empirically test the influence of the degree of digital economic connectivity among countries(regions)along the Belt and Road on their trade closeness and its mechanism.The results show that the degree of digital economic connectivity among countries(regions)along the Belt and Road has a positive promoting effect on their trade closeness;The geographical distance,cultural distance and tariff barriers of countries(regions)along the Belt and Road have a significant inhibitory effect on the closeness of trade between countries;Improving the degree of digital economic connectivity between countries(regions)along the Belt and Road can weaken the inhibitory effect of geographical distance,cultural distance and tariff barriers on trade closeness;The mechanism by which the degree of digital economic connectivity enhances trade closeness exhibits regional heterogeneity among different countries.Therefore,it is necessary to accelerate the development of the digital economy of countries(regions)along the Belt and Road,strengthen the digital economic connectivity among countries,improve the closeness of trade to promote the sustainable and healthy development of trade of countries(regions)along the Belt and Road.
