Abstract:In order to study the synergistic development of hi-tech industry innovation system, based on the synergistic degree model of composite system, this paper uses the data of Statistical Yearbook of China's High-tech Industry from 2009 to 2016 to measure the order degree of subsystems and the synergy degree of composite system, and clusters the analysis results of various industries, then analyzes the results for clustering. The results of the study show that: the innovation system of high-tech industry in China has a relatively low degree of cooperation, and the gap between the industries is more significant, and the two types of industry co-evolution levels represented by the manufacturing of communication equipment and the manufacture of chemicals are higher, and the order degree of the innovative absorption subsystem of the spacecraft is relatively low. On the basis of the existing research, the paper further refines the development status of cooperative innovation in various industries and puts forward corresponding suggestions in order to continuously promote the cooperative development of innovation system in high-tech industries in China.
