The landlord wants to publish core journals, but it is really difficult now, which is caused by multiple reasons: 1. Publishing a paper generally goes through the following processes: submission, review, employment/rejection, modification and polishing, final review, finalization, proofreading, typesetting, printing, publishing and mailing. The normal review time is 1-7 days or 1 month-1 year. 2. The State Administration of Press and Publication and the State Administration of Radio, Film and Television merged into the State Administration of Press, Publication, Radio, Film and Television, and the quality of periodicals became more and more strict, and the requirements of magazines for manuscripts also increased accordingly, which took time in the process of reviewing and revising manuscripts. Great changes have taken place in the external publishing environment, and a number of magazines with poor quality have closed down one after another. A number of articles that have been finalized cannot be published normally, and the number of periodicals that can be published is reduced, which leads to more intense publishing competition. 4. In order to review the core journals, most journals that want to develop are constantly compressing the layout and improving the quality of manuscripts, which greatly increases the probability of papers being rejected or revised. In the face of unexpected time such as annual review, the publishing cycle of magazines will suddenly change, and the articles that have been planned to be published may be postponed. The author should reserve time for various factors to avoid delaying publication due to unexpected circumstances. The normal review period of core journals is 1-3 months, and the review is strict, and the chances of rejection and revision are greater, which means that the process takes longer; Moreover, the layout of core journals is limited, and the competition for submission is more intense. Even if you are hired, the publication time will be much later than that of ordinary journals, so it is faster to find some agencies. I evaluated my professional title last year, and just now, Chinese periodicals went online and published an economic article, which was quite fast.
