As far as the administration of periodicals is concerned, there are no criteria for distinguishing between provincial and national periodicals. The national press and publication administration has long stated that chinese publications are of a formal and informal nature, that there is no so-called hierarchy between national and provincial levels, and that they are of the same level, regardless of whether they are hosted, run by or in charge of the province, autonomous regions, or national institutions, departments and groups, and that they are open to distribution across the country. In practice, however, many often describe a publication as national in nature, one that is provincial, provincial, municipal and internal, a division that is of some practical relevance. Especially in the case ofReview of functional titlesAt times, it is possible to evaluate the academic standards of authors. From this academic point of view, periodicals are classified academicly into ordinary journals andCore periodicalsMore appropriate. Universal issues usually refer to periodicals other than core periodicals, which generally refer to north chinese core periodicals, csci-source periodicals and statistical-source core journals, and also include cscds. As a result, the division of provincial periodicals in the usual sense is more in the main administration of the head of the journal. Usually, national periodicals refer to directors and sponsors as national units, while provincial periodicals refer to directors as provincial units, which usually cover a wide range of subject areas such as natural sciences, social sciences, engineering technology and humanities。
