Abstract:With the in-depth exploration of think tank construction, the rational development of think tanks and the output of high-quality research results have received increasingly attention in China. Nevertheless, the existing think tank research generally focuses on the part of the think tank problem, and it lacks the systematic thinking and cognition of the whole process of think tank research. To this end, based on the principle of think tank Data-Information-Intelligence-Solution (DⅡS), this study proposes a three-dimensional theoretical model of think tank DⅡS from the perspectives of research process, think tank orientation and method tools. Furthermore, the proposed model is analyzed from different views, including the main view of the research process and think tank orientation, the top view of the research process and method tools, and the left view of the method tool and the think tank orientation. Through the research, this study aims to explore the systematic methodology of think tank research and make contributions to the construction of high-quality think tank in China.
