新冠肺炎疫情的蔓延，使得全球货物贸易和服务贸易受到巨大冲击。而贸易数字化的发展，有效缓解了疫情对全球贸易的冲击。自首届进博会举办以来，以电子商务为主要形式的贸易数字化一直伴随其发展，特别是第三届进博会的展品、展览等的数字化趋势更加明显，从一个侧面反映了全球贸易行业、展会模式、贸易促进方式、贸易规则的数字化发展趋势。建议以进博会为平台，依托大数据、区块链、人工智能等科技，完善数字贸易基础设施，持续推动贸易主体数字化，以区块链技术运用提升跨境货物贸易通关效率，探索兼顾效率和安全的数据跨境流动监管模式。
The COVID-19 pandemic brings a huge impact to the development of global trade in goods and trade in services. However，the development of trade digitalization effectively eases and remedies the impact of the pandemic on global trade. Since the first China International Import Expo（CIIE）was held，it has been accompanied by trade digitalization mainly in the form of e-commerce，and the digitalization trend is especially obvious at the third CIIE in terms of booths，exhibition halls，displays and forums，which represents the digitalization trend of global trade industry，exhibition mode，trade promotion approaches and trade rules. This report suggests that through the platform of CIIE，and based on technologies including big data，block chain and AI，we shall promote infrastructure construction for trade digitalization，tamp the foundation for trade digitalization by gathering the digital subjects，promote customs clearance efficiency with block chain technology，and explore the efficiency and safe supervision modes for cross-border data flow.
