Abstract:It will provide relevant decision support for discipline development and science and technology policy formulation in Carbon Peaking and Carbon Neutrality (CPCN) to concern professional scholars which are relatively stable research groups, and analyze the current situation in science and engineering disciplines which are important scientific and engineering foundations for carbon emission reduction, carbon reduction and carbon sequestration. From the perspective of scientific productivity, the concept of professional scholars is introduced, and 11 science and engineering disciplines related to CPCN are identified according to literature survey and suggestions of experts. Afterwards, scientific papers are collected from 67 important journals based on the mapping table between journals and disciplines. The analysis dataset is created based on keyword statistics, expert experience, and classification algorithms. The professional scholars among authors are determined according to the characteristics of publication counts. Then, personnel investment indicators, scientific output indicators and knowledge innovation efficiency indicators are designed to discover prominent problems by analyzing and comparing the development characteristics of professional scholars in various disciplines. The results show that the overall growth of authors and publications in CPCN disciplines in China is relatively fast. As for professional scholars, their scientific publications are clearly dominant and they are the main contributors to new knowledge in CPCN disciplines. However, their speed of creating new knowledge is slower than that of ordinary authors. Their scientific productivity is also much higher than that of ordinary scholars, and their growth speeds in scientific productivity is significantly better than other authors in all disciplines with the exception of the discipline of petroleum and natural gas engineering. At the same time, two prominent problems are found. The first problem is that there are some obstacles in the development of CPCN science disciplines. The second problem is that the declining of scientific productivity has emerged in four CPCN engineering disciplines, namely environmental science and engineering, transportation engineering, oil and gas engineering, and mining engineering. In particular, the scientific productivity of professional scholars has significantly decreased in four engineering disciplines, namely chemistry, atmospheric science, oil and gas engineering, and environmental science and engineering. In response to this, some constructive suggestions are proposed, such as attaching importance to CPCN science disciplines, improving the scientific productivity of scholars, and fully leveraging the talent and achievements advantages of CPCN engineering disciplines.
