1, nationwide, such as: national periodical award, national 100 key social science journals, Chinese science citation database source journals, China humanities and social sciences core journals selected, Chinese academic journals comprehensive evaluation database source period, China humanities and social sciences citation database source journals, China scientific papers statistical sources, etc.

2. Provincial periodicals, such as * * provincial first-class periodicals, * * provincial top ten periodicals and * * provincial periodicals.

4. Classification of periodicals formulated by institutions of higher learning, such as Core Journals of Nanjing University, Catalogue of Domestic Journals of Hunan University, Catalogue of First-class Important Academic Journals of Hubei University, etc.

As the periodical is the main garden for publishing scientific research achievements, the periodical level involves many aspects such as periodical management, editing, author award, selection, professional title, promotion and so on. In real life and work, the division of periodical level is much more complicated than the above. For example, there are several ways for the evaluation conditions of senior professional titles in a province to involve periodical grades:

(1) Publications at or above the provincial level

(2) Professional academic journals at home and abroad

(3) Academic journals at home and abroad

(4) Academic journals above the provincial level

(5) provincial publications

(6) ministerial newspapers and magazines.

At present, the academic institutions that recognize the comparison of periodical grades in China are:

(1) Overview of Chinese Core Journals of Peking University Library and Peking University Library Journal Work Research Association.

(2) The source journal "Citation Index of Chinese Social Sciences" jointly developed by Nanjing University and Hong Kong University of Science and Technology.

(3) Awards for Social Science Journals of Colleges and Universities sponsored by the Research Association of Liberal Arts Journals of Colleges and Universities.

(4) The source journals of China Academic Journals (CD-ROM) Electronic Magazine, China Academy of Sciences Literature Information Center, Chinese Academy of Social Sciences Literature Information Center, Peking University Library, China Academic Journals Comprehensive Evaluation Database, China Science Citation Database and China Humanities and Social Sciences Citation Database.

(5) China Core Journal of Humanities and Social Sciences, Document Information Center of Chinese Academy of Social Sciences.

(6) Periodical classification catalogue formulated by key universities, etc.
