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 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.

Differences between National Periodicals and Provincial Periodicals

The difference between provincial periodicals and national periodicals: in fact, the state has never classified publications, which means that there is no difference in influence and professionalism between provincial periodicals and national periodicals. The so-called distinction between national periodicals and provincial periodicals is mainly for the convenience of management, according to the level of periodical authorities. That is, the periodicals in charge of state units are national periodicals, and the periodicals in charge of provincial units are provincial periodicals.

1。 Domestic legal periodicals and illegal periodicals

Domestic periodicals are divided into formal periodicals and informal periodicals. Regular sci-tech periodicals are approved by the State Press and Publication Administration and the State Science and Technology Commission within the agreed number and incorporated into the "unified domestic serial number". The application for running a journal is relatively strict, and the editor-in-chief and deputy editor-in-chief must be held by senior professional and technical personnel. There are certain requirements for the quality of editors, and regular periodicals have independent publishing policies. An informal periodical refers to a periodical that is approved by the administrative department to receive the "approval of internal newspapers and periodicals" as internal communication (generally limited to internal communication and not publicly issued), but it is also a legal periodical. Generally speaking, formal journals have gone through the process of informal journals. Illegal periodicals refer to illegal publications that are not registered as "internal publications" without the approval of the Press and Publication Administration and the State Science and Technology Commission. Their primary purpose is to make a profit and charge a high page fee. They are technically and politically irresponsible and cannot be issued publicly or internally in China. They usually spend 300 yuan to buy an ISSN number abroad to cheat teachers.

2. Number of domestic periodicals

All the official periodicals approved by the State Press and Publication Administration and the State Science and Technology Commission are incorporated into the "Domestic Unified Number". The serial number of official periodicals consists of two parts: the international standard serial number (ISSN) and the domestic unified serial number (CN) (the legal distribution of overseas periodicals in China must be filed by the Press and Publication Administration and approved by China Library Corporation, etc.). ). "CN" is the country code of China, lacking "domestic unified serial number (or domestic recognized serial number)".

Three Methods of Identifying Official Periodicals Publicly Published in China

Domestic public periodicals are allowed to be distributed at home and abroad, with a unified domestic serial number. Their serial number structure is: CN newspaper registration number/classification number. Only ISSN international serial numbers without a unified domestic serial number are not allowed to be publicly issued in China, and some are printed with CN(HK) or CNXXX (HK)/R, which are domestic serial numbers fabricated by domestic lawless elements to deceive readers who are eager to publish papers. The legal domestic unified serial number shall be indicated. Generally speaking, domestic official periodicals have the competent units of domestic state organs (non-China/China XX Association), and there are detailed editing and publishing mailing addresses and printing and publishing places in China. In addition to self-issuance, most of them are subscribed by post offices, so there are often postal codes. However, illegal periodicals only have international standard serial numbers or domestic CN serial numbers, even if they are "internal newspaper certification".

To sum up, papers published in international journals and magazines that have certain international influence and domestic approval numbers can be used by authors to improve their international popularity and influence. Of course, papers published in illegal journals may not be recognized in China. It should be said that it is meaningless to evaluate professional titles. As for how to resist the prevalence of these "illegal periodicals", on the one hand, the domestic press and publication departments should seriously investigate and deal with these "periodicals" to prevent legitimate newspapers from becoming such "periodicals"

The standard format of CN serial number is: CN XX-XXXX, in which the first two digits are the area numbers of provinces, autonomous regions and municipalities directly under the Central Government, and CN(HK/H) or CNXXX(HK)/NR/R is printed, which is not a legal domestic unified serial number.

The first two XX codes in the format are as follows: 1 1. Beijing 12. Tianjin 13. Hebei 14. Shanxi 15. Inner Mongolia 2 1. Liaoning 22. Jilin 23. Heilongjiang 365448. 35. Fujian province Jiangxi province 37. Shandong province 4 1. Henan province. Hubei province. Hunan province. Guangdong province. Guangxi Zhuang Autonomous Region. Hainan province. Alternate number 48. Alternate number 49. Alternate number 50. Chongqing 5 1. Sichuan province. Guizhou province 54. Xizang Autonomous Region.

According to state regulations, it is illegal to run a magazine in different places. If the friends who submitted the journal find that there is no serial number in the above area, they should be able to compare and judge.
