Abstract: In considering the characteristics of high-tech industries and reference to the literature, a set of factors that may have effect on industrial technological innovation capability is collected. Then, by using the statistic data from the government, the factors are optimally selected such that an index system for technological innovation capability evaluation of high-tech industries is developed. Further, based on this system, a model for evaluation of technological innovation capability mutation in high-tech industries is presented by introducing the catastrophe progression method. It is applied to five major high-tech industries in China to demonstrate the effectiveness of the proposed method.

Key words: high-tech industries, technological innovation capability, catastrophe progression method
