Abstract:Based on the view of the complex system theory, this article divides the regional sci-tech innovation complex system into 4 subsystems, including scientific research and development institutions subsystem, higher education subsystem, science and technology enterprise subsystem and supporting environment subsystem. Based on the statistics of 31 provinces of China from 2009 to 2015, the synergy degrees of complex system and the order degrees of the 4 subsystem are measured by using the synergy degree model of the complex system. It is found that the synergy degree of science and technology innovation complex system is low in China, there are variations in the order degrees of the 4 subsystems of the regional sci-tech innovation complex system, and the regional sci-tech innovation complex system of each province has appeared "the short plat phenomenon" to different degrees, which seriously restricts the coordinated development of the science and technology innovation complex system of provinces.
