Abstract: Taking the evolution of enterprise independent innovation dynamic mechanism as the main line and Jiangxi Zhengbang Technology Co., Ltd as the sample, this paper adopts the SPS case study method to analyze the evolution path of enterprise independent innovation driving factors, so as to explore the dynamic mechanism structure, the phase characteristics and the operation mechanism of enterprise independent innovation. The findings indicate that the evolution of enterprise independent innovation mechanism can be divided into three stages: variation, replication and selection. And a certain evolution path is followed, that is, from the exogenous drive during the process of the technological innovation, to the endogenous drive during the process of the institutional innovation, finally to the coordinated drive during the process of the coordinated innovation. Meanwhile, during such processes, the dynamic mechanisms of enterprise independent innovation at different evolution stages are different in the innovation levels, methods, features and so on.
