Abstract:There are few studies on the science and technology (S&T) innovation of Marine strategic emerging industries from the perspective of the Industry-University-Research Institute (IUR) collaboration. To fill this research gap, the IUR collaboration adopted by maritime powerful nation in western to promote the development of Marine bio-pharmaceutical industry was taken as the research sample, this paper adopts the research perspective of the S&T innovation value chain to clarify the impact mechanism of IUR collaboration in the process of S&T innovation of Marine strategic emerging industries, and finds that the IUR collaboration is disjointed in the innovation value chain in China. Specifically, the favorable situation of "the basic research on the front end of the innovation chain promotes the development of industrial technology and production management on the back end of the innovation chain, and the back end feeds the front end" has not yet formed. Finally, this paper analyzes the existing problems of IUR collaboration innovation in China's Marine strategic emerging industries from the perspective of three steps of Marine S&T innovation (i.e., knowledge generation, knowledge development and knowledge commercialization) and puts forward some corresponding suggestions and countermeasures.
