Abstract:Technology brokers can strengthen the coupling relationship between the participants of scientific and technological achievements, and are important implementers to promote the effective transformation of scientific and technological achievements. Based on the theory of information asymmetry, this study clarifies the characteristics of the main elements in the transformation of scientific and technological achievements, and proposes the coupling relationship between technology brokers in promoting the transformation of scientific and technological achievements. The main conclusions are: The process of transformation of scientific and technological achievements is essentially a process of knowledge and information flow , and technology brokers play the role of "service" and "catalyst" in the process of transformation of scientific and technological achievements; technology brokers take scientific and technological achievements as the service object, which can promote the effective connection between the supply and demand of scientific and technological achievements, and strengthen the interaction between various subjects. ;Technology brokers adjust information and knowledge differences between subjects, uncoordinated goals, conflicts of interest and other issues through information coupling mechanism, knowledge coupling mechanism, target coupling mechanism and interest coupling mechanism, and strengthen communication and coordination among multiple knowledge innovation subjects. Effectively promote the efficient transfer and transformation of scientific and technological achievements.
