Based on the manufacturing export data of 44 countries from 2014 to 2020,a moderated mediation model is constructed.The results show that digital trade barriers inhibit the quality improvement of manufacturing exports,especially in the fields of payment systems,electronic transactions and infrastructure connectivity.The inhibitory effect of digital trade barriers on the quality of technology-intensive manufacturing exports is greater than that of capital-intensive and labor-intensive manufacturing,and it mainly targets developing countries,and has no significant impact on developed countries.Further analysis shows that technological innovation plays a partial mediating role between digital trade barriers and manufacturing export product quality,and the heterogeneity of digital trade regulatory policies negatively moderates the direct path of the intermediary model and positively moderates the first half path,that is,higher digital trade regulatory differences can weaken the inhibitory effect of digital trade barriers on manu-facturing export product quality.But it stifles technological innovation.Based on the conclusions,suggestions are put forward to promote the level of digital trade openness,increase investment in digital research and development technology and improve the supporting policies of digital regulation.
