Research Progress and Trend Prospect of Blockchain Technology Application in Logistics and Supply Chain Information System under Pandemic-hit

The logistics and supply chain of pandemic prevention materials is an important pillar of the pandemic prevention and control system, and the information system is the "Nerve Center"that ensures the efficient operation of the logistics and supply chain. Blockchain technology has the characteristics of transparency and credibility, tamper-proof traceability, privacy security and high reliability of the system, and it is of great significance to study how to apply blockchain technology to improve the logistics and supply chain information system of pandemic prevention materials, so as to better cope with the current and possible future pandemic. To this end, this paper uses the literature analysis method and knowledge map method to reveal the research status, hot spots and evolution context of blockchain technology application in the logistics and supply chain information system under pandemic-hit. The research results show that there is a significant correlation between the number and theme changes of relevant literature and the progress of pandemic prevention and control. There have been a number of research hotspots, but they are still relatively scattered. There are few studies on the organic combination of blockchain technology application, pandemic prevention and control, the logistics and supply chain information system. Looking forward to the research trend, in the future, blockchain can be integrated with the Internet of things, cloud computing, big data, etc., so as to ensure the efficient operation of pandemic emergency logistics, help the management of pandemic material donation, and improve the pandemic medical material supply chain information system.
