Abstract /摘要

How to ensuresupplysecurityofcriticalmetals isacommon challenge for China and even developed countries. With the rapid developmentofinformation and communication technology (ICT), its impactsonthesupplyofcriticalmetalneed to be discussed. Taking China as an example, this article studies the influencesofhetero-geneousICTonprimaryandsecondarysupplyofcriticalmetals and explores their influencing mechanisms. The results show that: (1) In theprimarysupply,ICThas inverted U-shaped influencesonthe host metals, while the impactsonbyproduct metals antimony and nickel are U-shaped and linear promotion respectively;ICThas linear promotingeffectsonsecondarysupply. (2) Compared with hardware and communication equipment, software products have the most obvious impactonbothprimaryandsecondarysupply. (3) Industrial scaleofmining (SM) and smelting (SS), energy structure (ES) and energy efficiency (EE) can enhance the impactsofICTontheprimarysupply; while only SS enhances the impactsonthesecondarysupply. (4) In theprimarysupplyofhost metals, the improvementofEE and ES will shift the inflection point to the left due to crowding-out effect, while the opposite is true for SM.
