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.
期刊介绍：
The bi-monthly China & World Economy was launched in 1993 by the Institute of World Economics and Politics, Chinese Academy of Social Sciences (CASS). It is the only English-language journal in China devoted to the topic of the Chinese economy. The journal aims to provide foreign readers with an objective, impartial, analytical and up-to-date account of the problems faced and progress made by China in its interaction with the world economy. Among its contributors are many distinguished Chinese economists from both academic and government circles. As such, it has become a unique window on China and is essential reading for all those concerned with China"s development.
