Abstract: 【Purpose/significance】Existing studies focus on the components and operation mechanism of the knowledge service capa⁃bility of science and technology think tanks in a stable policy environment. However, with the change of policy environment and eco⁃nomic situation, science and technology think tanks need to improve dynamic knowledge service capability to meet the diverse and het⁃erogeneous needs of policy consultation.【Method/process】Based on the theoretical research and operation practice of the science and technology think tank, the connotation and characteristics of the science and technology think tank are clarified, and the dynamic knowledge service capability system of the science and technology think tank is constructed based on the dynamic capability theory.
【Result/conclusion】Based on the operation process of science and technology think tank, dynamic knowledge service capability is di⁃vided into environment scanning capability, opportunity identification capability, resource integration capability and achievement dis⁃semination capability. The micro basis of dynamic knowledge service capability of science and technology think tank is put forward from three aspects: organizational structure, personnel skills and communication mechanism.【Innovation/limitation】This paper inno⁃vatively proposes the dynamic knowledge service capability of science and technology think tanks, and constructs the dynamic knowl⁃edge service capability system around the constituent elements and micro basis. Cross-field comparative analysis and large sample em⁃pirical test are the further research direction.
