    Abstract: [Purpose/Significance] Carrying out research on emerging research topics(ERT) identification and scientifically and effectively discovering their characteristic correlation laws can better serve practical needs and give play to the innovative supporting role of sci-tech information research on the development of disciplines. Aiming at discovering emerging research topic(ERT) and its characteristic correlation effect scientifically and effectively, this paper carries out ERT identification and feature analysis, while realizing the innovative supporting role of sci-tech information work. [Method/Process] Starting from the definition of the features of ERT, this paper established the methodological framework of ERT identification by using natural language processing, global principal component analysis and time series analysis. Based on the relevant theories and practices of emerging topic identification and scientific impact assessment, this thesis quantified the characteristics of the topic’s consistency, novelty, influence, and growth. On the basis of emerging themes identification, the law of the development of emerging themes in the target field is deeply excavated. Granger causality test and cointegration analysis were used to explore the long term equilibrium and the correlation effects of their characteristics. [Result/Conclusion] This paper proposes a method to identify ERT and their correlation feature analysis. In order to verify the effectiveness and feasibility of this method, the field of wetland was selected to carry out empirical research. Combined with the topic identification and feature correlation effect analysis, the final result depicted the dynamic development path of subject science influence in this field, while putting forward some advices on developing emerging topics from the perspective of associated characteristics.

    Abstract: Achieving carbon peak and carbon neutrality goals is a major strategic decision made by the Chinese government, which will bring extensive and profound systemic changes for the economy and society. S&T is the core driving force that supports the goal of carbon neutrality. On the basis of the related concepts of carbon neutrality, this study analyzes the strategic actions and the characteristics of technological layout of carbon neutrality in developed countries/regions and international organizations. Major countries have promoted carbon neutrality through legislative regulation, energy strategies, technology roadmaps, carbon markets and other policy actions. They focus on deploying transformative green low-carbon technologies, such as hydrogen, CCUS, renewable energy, energy storage, nuclear energy, and clean power, to seize the technological commanding heights of the future green industrial revolution. Based on the two fundamental paths of achieving carbon neutrality — “emission reduction”, “increasing sinks”, and three research directions—“building a zero-carbon energy system”, “rebuilding low-carbon industrial processes”, and “ecological carbon sequestration and increasing sinks/negative emissions”, this study puts forward 14 important scientific issues aiming to guide more than 70 key technological breakthroughs. On the basis of all findings, 6 suggestions are proposed for China’s carbon neutrality strategy and technological layout as they are (1) strengthen the top-level design and scientific planning of the action plan for carbon neutrality; (2) accelerate the construction of the technology supporting system for carbon neutrality; (3) establish a zero#2;carbon energy system and a new power system; (4) accelerate the construction of the low-carbon industrial system; (5) promote the prospective applications of negative carbon emission technologies and the ecological carbon sequestrations; (6) Enhance the application of systematic solutions in carbon neutral strategic actions.

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-03-14

    Abstract: Purpose/significance Fundamentally, the core of the university-affiliated think tanks construction is the capability building. This paper systematically constructs the university think tank capability system, provides guidance and enlightenment for its improvement, and accelerates its construction in China. Method/process Based on the decision-making theory, policy process theory and its operating characteristics, this paper constructs the operating framework of university-affiliated think tanks constructs the capability system, and summarizes the current situation. Result/conclusion The elements of university think tank capability system includes basic capability, intelligence capability, achievement output and innovation capability, political capability
    and service capability. The basic capability of that is strong, but the others are insufficient. Therefore, it is important for university-affiliated think tanks to emphasize intelligence, persist academic orientation with academic research and policy research together, take policy consultation as the main direction, and establish service concepts and improve service capability at multiple levels.
