Abstract:The vigorous development of high-tech industry is very important to the role of technology innovation in the process, which becomes the core of competition around the world and academic research hotspots. In order to explore the evolution of the high-tech industry technology innovation ability of dynamic process, this paper to build China"s High-tech industry technology innovation ability of dynamic evolution of three-dimensional dynamic model, based on classical mechanics model. Starts from the logical thinking leading dynamic technological innovation ability via three angles including capability span , capability depth , life cycle of ability , to dimensional analyse High-tech industry technology innovation ability of dynamic evolution model. Found that the High-tech industry technology innovation ability of dynamic evolution process forms a curved surface similar to S type in space.
