What's the difference between a core journal and a C journal?

Core journals and C journals were two different academic journal classification systems. The main differences between them were in the evaluation criteria, scope of coverage, and reader groups. Core journals are a type of core academic journals evaluated by the China Academic Periodical Evaluation Foundation. They are an important platform for academic research and communication in the academic community, with a high academic reputation and influence. The evaluation criteria for core journals were mainly based on the quality of academic journals, academic influence, number of journals, and other factors. The C-journal referred to the academic journals included in the China Academic Periodical Comprehensive Evaluation database (CCN). It was a classification method for Chinese academic journals and an important part of Chinese academic journals. The journal covered a wide range of academic research fields, including natural sciences, social sciences, engineering technology, and so on. Magazine C's readers were mainly professionals from academia, research institutes, and companies. Core journals and C journals had different evaluation standards, coverage, and reader groups, but both were authoritative and influential academic platforms. They were of great significance for academic research and academic exchanges.
