Abstract: Industry-university-research institute（IUR）collaborative innovation has become the leading-edge innovation mode to promote significant knowledge and technological innovation in China. IUR collaborative innovation process can be regarded as the flow of knowledge between enterprises and universities（or research institutions）two types of heterogeneous knowledge organization.Therefore， this paper divided IUR collaborative innovation process into three progressive evolution stages from the perspective of knowledge-flow， including knowledge sharing， knowledge creation and formation of knowledge advantage， analyzed internal operation mechanism and synergistic characteristics of the whole process， initially established a theoretical framework of industry-university-research institute collaborative innovation process based on knowledge flow
