Abstract:The purpose is to explore a new theoretical model of collaborative innovation, and to establish the model of knowledge interaction influencing factors in collaborative innovation process; It provides a theoretical basis and guidance for enterprise collaborative innovation activities;Through the literature reading method, the paper summarizes the previous research on collaborative innovation theory, and comments;A new theoretical framework for collaborative innovation is put forward; It will be divided into three stages of collaborative innovation. In the process of collaborative innovation, the effect of knowledge interaction has a direct impact on innovation performance. This paper further explores the elements of knowledge interaction in collaborative innovation. This paper reviews and reviews the research viewpoints of each knowledge interaction influencing factor, and establishes the influencing factors model in different stages of collaborative innovation. This paves the way for the empirical study of the weights of the influencing factors.
