Why do I have to pay for publishing a paper? This question is not very rigorous. The more accurate question is, why do you have to pay for publishing papers in many cases? Why do you use such wording? Because in fact, not all journals have to charge a page fee for publishing papers. There is also a part that does not charge page fees. Not only does it not charge, but it also pays the manuscript fee. It's just that this ratio is relatively small, or there are some, but you don't know if you can't touch it. Or know, for the average person is published. This is the specific situation now.

But most academic journals charge a page fee. Why do you charge a page fee? Well, if you look at foreign periodicals, such as SCI, the page fee is also more than 1000 yuan or several hundred euros, which is not very cheap according to our domestic situation. Therefore, the charge for publishing papers is the overall situation, not unique to us. So, why charge the page fee? Originally, I wrote a good article, and you hired it and published it in your journal. You should give me the manuscript fee, at least you can't let me pay it back. What about this situation you're talking about? Tao Tao newspaper tells you that it is actually another kind of periodical, that is, a periodical subscribed for publication, such as Reader, Novel Monthly, Story Club, Companion and so on. Such periodicals can survive or make profits by publishing and subscribing, and naturally have the ability to pay the authors. Academic journals are mainly aimed at professional groups, and ordinary people can't read them at all or can't understand them. At this time, he can no longer survive by publishing, but only by charging a certain page fee to maintain his daily expenses, office expenses, periodical editing expenses, editing wages and so on. Therefore, many academic journals charge a page fee. And why do some academic journals not charge publishing fees, but also return the manuscript fees? This is because people have allocated funds to him, and hundreds of thousands of millions of operating expenses will be allocated to the magazine every year. At this time, if they have no problem living, they will send a manuscript fee to an author, so the quality of the paper is also higher. This is the case now.

Well, I hope you know something about the fees for publishing papers. If you have the ability, you can find some free journals to publish, but this requires that your papers are of high quality. So this requires you to know your own situation.
