There has never been any classification between provincial periodicals and national periodicals, that is to say, there is no difference in influence and professionalism between provincial periodicals and national periodicals. The authoritative order of different journals is: SSCI source journals >; EI source magazine > Chinese core (Nantah core, Peking University core) > EI conference, CPCI conference > international and national journals > provincial journals > other general journals.

When submitting a manuscript, remember to search which databases this journal is included in and whether it meets the graduation requirements. In addition, many schools have established their own journals list, so we should not only look at the official database, but also take the list published by the school as the standard.
