By the end of 20001,there were 8,889 kinds of periodicals in China, all of which were approved by the General Administration of Press and Publication and issued under the unified domestic serial number. Journals with unified numbers in China are all official publications. The General Administration of Press and Publication has never classified these periodicals according to their academic level. Only from the perspective of publishing management, according to the different permissions of periodicals, can periodicals be divided into central periodicals and local periodicals, and effective administrative management can be carried out according to the different permissions of periodicals. Some periodicals publish the words "national first-class periodicals" on the cover, which is not selected by the General Administration of Press and Publication, nor is it a government act.

According to the most authoritative press and publication administration, there is no standard for distinguishing between countries and provinces for periodicals and magazines. If the unit has no special regulations, there is really no need to pay too much attention to the level difference between countries and provinces.

However, in practical application, some units still have different divisions of national and provincial publications, and these standards are used to some extent in the evaluation and employment of professional titles.

To sum up, it is generally believed that "national" periodicals refer to periodicals sponsored by the central authorities, ministries and commissions in the State Council, Chinese Prefix Society (like china law society), China Academy of Sciences, China Academy of Social Sciences, democratic parties and national people's organizations, as well as periodicals sponsored by national professional societies. "Provincial" periodicals, that is, periodicals sponsored by provinces, autonomous regions and municipalities directly under the Central Government and their subordinate ministries, commissions, departments and bureaus, and journals (periodicals) sponsored by colleges and universities.

For what CN publications, this problem should really attract our attention.

A formal publication generally has two serial numbers, one is ISSN, also called international serial number, and the other is CN serial number, also called domestic standard serial number. International serial numbers are not difficult to achieve, because magazines are loosely managed abroad, and registering a magazine is as simple as registering a company. However, the CN number is different. In China, the management of magazine registration is very strict. Private people are not allowed to run magazines, and neither are enterprises. Only state organs and institutions should register with the press and publication bureau and accept the annual review. All publications registered with the Press and Publication Bureau have CN numbers. This is the most important thing for most professional titles and colleges, otherwise it will be regarded as a local publication or an internal publication and cannot be regarded as an academic achievement.

1. What is a national journal? Provincial periodicals?

Generally speaking, "national" periodicals refer to periodicals sponsored by the Central Committee of the Communist Party of China, the State Council and their subordinate departments, or 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 as "national journals" and "core journals" can also be regarded as national journals. "Provincial" periodicals, that is, periodicals sponsored by provinces, autonomous regions and municipalities directly under the Central Government and their subordinate ministries, commissions, departments and bureaus, and journals (periodicals) sponsored by colleges and universities.

2. What is an academic journal?

Academic journals mainly publish academic papers, while non-academic journals mainly publish documents, reports, speeches, experiences, knowledge, etc., which can only be used as materials for academic research, but not as articles of papers. Because the selection of "General Introduction" is based on "a large number of articles published", "a large number of articles included" and "a large number of citations", it does not emphasize the boundary between academic journals and non-academic journals, and naturally there is no strict distinction. Specifically, the summary is academic and non-academic, mainly in two aspects, one is the nature of the journal, and the other is the purpose of the journal.

3. What is a CN publication?

The so-called CN publications refer to publications registered in China and publicly distributed in China. The serial numbers of these publications are all marked with the letter CN, and people are used to calling them CN publications.

4. What is an ISSN journal?

The so-called serial number publications refer to publications registered outside China and publicly distributed at home and abroad. The serial numbers of such publications are preceded by ISSN letters.

. Now many magazines have CN and ISSN numbers.

5. What is a core periodical?

To put it simply, core journals are the most important core journals, which are tracked and evaluated by academic circles through a set of scientific methods and classified and graded according to the theory of information science.
