摘要
This study examined the impact of digital inputs on global supply-chain security.Using data from the Asian Development Bank Multiregional Input-Output database,covering 62 countries or regions and 35 industries from 2007 to 2022,digital inputs were found to enhance the level of supply-chain security significantly.In times of crisis prevention,digital inputs not only improved supply-chain security but also contributed to a notable recovery effect.Mechanism tests indicated that digital inputs enhanced supply-chain security mainly by improving information transmission efficiency and increasing both demand-side and supply-side information transparency.Heterogeneity analysis indicated that all three mechanisms were significant in the manufacturing sector,but demand-side information transparency was not significant in the service sector.Further analysis identified post and telecommunications sector as having the greatest positive impact on supply-chain security.
