Digital Inputs, Information Transparency, and Global Supply‐Chain Security

Abstract 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.
