Key Core Technological Breakthroughs in Dual-chain Coupling Under the Perspective of New Quality Productivity
New quality productivity is the inherent requirement and important focus of promoting high-quality development.Break-throughs in key core technologies are the key to protecting existing productivity and developing new quality productivity.With the help of the technology growth S curve and industry life cycle curve theory,this paper considers the differences between developed and develo-ping countries,and divides breakthroughs in key core technologies into two situations:existing technologies are subject to technological sanctions and breakthroughs in the new S curve for cutting-edge technology.The productivity issue is discussed in combination with the two coupling modes of innovation chain and industrial chain.The first is that the innovation chain"empowers"the industrial chain.When existing technologies are subject to technological sanctions from developed countries,they protect and improve existing productivity through breakthroughs in key core technologies;the second is that the innovation chain"derives"the industrial chain,and new quality productivity is formed through breakthroughs in cutting-edge key core technologies.The research conclusions have theoretical reference and practical guiding significance for the systematic understanding of the idea of new quality productivity.
