Recently, the journal evaluation report World Journal Clout Index (WJCI) (2020 Science and Technology Edition) jointly launched by the Institute of Science and Technology Information of China and other institutions was released, and Journal of Time and Frequency sponsored by the National Time Service Center was indexed.
The World Journal Clout Index (WJCI) Report (2020 STM) is the research result of the “Research on the Comprehensive Evaluation Method of World Science & Technology Journal Impact” commissioned by the China Association for Science and Technology. This project aims to establish a new journal evaluation system and explore a global-oriented journal impact evaluation method on scientific, comprehensive and reasonable basis, with a view to contributing Chinese wisdom and Chinese solutions in the field of academic evaluation and promoting the fair evaluation and equal use of sci-tech journals worldwide.
The WJCI Report (2020 STM) determines the proportion of source journals in each country/region from four dimensions: R&D input, output of research papers, number of researchers, and the scale and level of journals. This report selects about 15,000 high-level journals representative of the region, discipline and industry as source journals from 63,000 or more active sci-tech academic journals worldwide. This novel system comprehensively covers all sci-tech fields and reflects the development of emerging and cross-disciplinary disciplines, following the general outline of the Classification and Code Disciplines of the People’s Republic of China, with reference to the Chinese Library Classification and Disciplinary Classification for Degree Granting and Talent Training, etc. Among them, 1426 Chinese sci-tech journals are included, and the average WJCI index is 1.185. After deliberation, experts generally believe that these journals, like other journals in the report, have reached the level of international excellent journals.
WJCI report more comprehensive, objective and comprehensive evaluates journals of science and technology in today's society to publishing communication service provided by the global science and technology innovation activity and its academic influence. As the only publication in China specializing in reporting on the work of time and frequency, Journal of Time and Frequency will take this as a new starting point to continue to forge ahead, run the Journal well, and promote the high-quality development of academic journals.
