State-level periodicals, that is, periodicals sponsored by the Central Committee of the Communist Party of China and the State Council and their subordinate departments, or periodicals sponsored by China Academy of Sciences, China Academy of Social Sciences, democratic parties and national people's organizations, and periodicals sponsored by national professional societies. In addition, publications clearly marked with the words "national journals" and "core journals" can also be regarded as national journals. But the above is just the general situation, and there are many local journals with high academic value and great influence that also belong to national journals. Such as Yunnan Botany, huazhong architecture and Journal of Harbin Institute of Technology. Please refer to the documents issued by relevant government departments. Note that there are also national key periodicals and periodicals with higher level, such as SCI, which should not be confused with national periodicals.
