摘　　要：区块链技术的去中心化特征为解决商业生态中“缺乏信任”这一核心问题提出新思路,通过“四色猜想”,归纳出“4+1”跨境贸易区块链应用基本模式和扩展模式,并且采用平行进口实际场景对上述内容进行验证。结果表明,该模式不仅能够构建安全可信的跨境区块链数字机制,满足平行进口这一新型贸易业态要求,而且可以有效促进贸易便利,可以为区块链技术应用、跨境贸易机制设计提供一定参考。The decentralized feature of blockchain technology provides innovative solutions to solve the core problem of lack of trust in business ecology.With the reference of"The Four-Color-Map Conjecture",this paper summarized the basic"4+1"cross-border trade blockchain application mode,as well as its extension mode,which provided a feasible and effective solution in the“Parallel-Imported Cars under Bonded Warehousing”scenario.The results demonstrates that the two models can not only build a safe and credible cross-border blockchain digital mechanism to meet the requirements of this new trade format,but also promote trade facilitation.This paper can be a valuable reference for related research of blockchain technology application and the establishment of cross-border trade mechanism.
