技术创新是产业系统演进的基础,产业系统的演进是技术创新带来的必然结果。产业升级实质上是技术升级,技术升级有三种形式,一是链内升级,由产业链的低端向高端攀升,由渐进性的技术创新带来产业的技术进步;二是链间升级,表现为一条技术链升级到另一条技术链,由根本性的技术创新导致;三是链间跨越,越过技术发展的几个阶段,由较低的技术链向更高的技术链跃迁,跨过中间的技术链,也是由根本性的技术创新导致。
Technological innovation is the foundation of industrial system evolution. The evolution of industrial system is the inevitable result of technological innovation. Industry upgrading is essentially a technology upgrade. There are three forms of technology upgrading. One is upgrading within a chain, rising from the low end of the industry chain to the high end, and bringing about technological progress in the industry through gradual technological innovation. The second is upgrading between chains For a technology chain upgrade to another technology chain, caused by a fundamental technological innovation; third is across the chain, over several stages of technological development, from a lower technological chain to a higher technological chain transition across the middle The technological chain, but also by the fundamental technological innovation led.
