Based on the concept of think tank policy influence and a large number of empirical cases， this paper reveals that the phenomenon of "instruction-centric" is prevalent in the evaluation of think tank policy influence in China. Based on the theory of policy process, this paper makes a bibliometric analysis of the internal references and instructions in the "China Think Tank Index", analyses the main problems brought about by this phenomenon, and preliminarily explores the method of breaking the "instruction-centric" method in the evaluation system of think tanks, with a view to providing reference for the evaluation and construction of new think tanks with Chinese characteristics in the new era.
