Abstract:Public opinion governance research is a typical think tank research driven by big data, which should deal with the "five major challenges" faced by China's economic transformation, social transformation, and reform challenges, namely, risk intertwined challenges, modeling complexity challenges, interdisciplinary challenges, social impact challenges, and scenario uncertainty challenges. The Think Tank Double Helix Methodology provides an effective research paradigm to guide the whole process of public opinion governance and think tank research. Based on this methodology, opinion research could effectively respond to the five significant challenges and serve the demands of national governance. This paper demonstrates a deep understanding of the relationship between the risk and value of the public opinion. It is also explained how to use the Think Tank Double Helix Methodology to promote the interdisciplinary integration of theoretical methods of public opinion academic research, improve the scientific and professional level of the logical framework of think tank research, and break down the cognitive barriers of the transformation from academic research to think tank research. This methodology provides thinking, process, operation, and organizational guidance. Under this guidance, we adhere to the problem-oriented, evidence-oriented, and scientific-oriented to conduct opinion think tank research. We establish a full-chain risk response mechanism, including public opinion collection, judgment, disposal, and response. We improve the risk rating system, including public opinion monitoring, early warning, prevention, and resolution, build a value shaping system including public opinion dissemination, guidance, influence, and credibility. This methodology promotes the research of public opinion think tanks from empirical to scientific research, from discrete to systematic approach, from a single discipline basis to comprehensive and consistent research from pure academic-oriented to integrative studies fitting both academic and practical requirements. These research transitions improve the quality and effectiveness of public opinion governance and think tank research for servicing decision-making.
