The World Journal Clout Index (WJCI) Report of Scientific and Technological Periodicals is the research result of the series project“Research on the Comprehensive Evaluation Method of World Science & Technology Journal Impact” commissioned by the China Association for Science and Technology. These projects aim 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 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 about 60,000 sci-tech academic journals being published worldwide. On the basis of thorough research on the journal classification systems of different citation databases, our research group creates a novel journal classification system. 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.The project has also established the World Citation Database, under the support of CrossRef and Digital Science, for calculating indexes and obtained the web usage data on CNKI, Wanfang, Chinese Medical Journal Full-text Database, Chinese Journal Network for Optics and Altmetric. Furthermore, a new journal impact evaluation index that integrates citation and web usage—World Journal Clout Index (WJCI) is formulated.

This website has detailed descriptions of report development methods in the "Research Report" and "Discipline" modules, and you can access the list of WJCI journals and their indexes through the "Journal Index" module and download the WJCI certificate in journal details page.
