Abstract /摘要：

Ensuring thesupplyofcriticalmetallicmineralis vital to addressing climate issues, andtechnologicalchangeis recognized as an important way to effectively improve thesupplyofcriticalmetallicmineral. Taking 14criticalmetallicmineralsub-sectorsinChinaas samples, this study first measures theirtechnologicalchange(TC), which is decomposed into magnitude oftechnologicalchange(MTC) and biasedtechnologicalchange(BTC). Then, the impact oftechnologicalchangeonthesupplyofcriticalmineralis explored and heterogeneity is considered. Finally, production scale and production cost are introduced as mediating variables to explore their influence mechanisms. The results show that: (1)technologicalchangepromotes the improvement of green total factor productivity (GTFP) ofcriticalmetallicmineralsub-sectorsinChinafromtwo dimensions of MTC and BTC,inwhich aluminum sector has the strongest promoting effect while antimony sector has the lowest promoting effect. (2) TC and MTCincriticalmetallicmineralsub-sectorshave a significant contribution tomineralsupply, but there is heterogeneity, withtechnologicalchangehaving a greater impactonthe mining industry than the smelting industry. (3)Technologicalchangeincriticalmetallicmineralsub-sectorscan indirectly guarantee thesupplyofmineralproducts by increasing production scale and reducing production costs.Insummary, more policies that are conducive totechnologicalchangeshould be developed, and it helps to guarantee thesupplyofcriticalmetallicminerals.
