Abstract:At present, domestic and foreign scholars on the research of enterprise innovation audit focus on technological innovation audit. And all the auditing methods take the form of self- evaluation tests based on the measurement of technological innovation in order to evaluate the ability of enterprise innovation flow and innovation. However, due to the complexity of innovation, the innovation of the technology is not able to truly reflect its innovation level, and it is difficult to achieve the purpose of audit. In this paper, a new method of enterprise innovation audit is proposed, which is based on the SECI model of knowledge transformation. The method includes four modules, which are related to the structure of the module. Through this kind of structure, more attention is paid to the hidden knowledge of enterprise employees. This method can find out the deep problems of enterprise innovation and propose effective solutions to promote the development of enterprise innovation ability.
