1. Publishing fee: This is the fee charged by a periodical for publishing articles, including editing, typesetting, printing and distribution. The cost of publication is usually borne by the author, but some journals will provide partial or full funding.
2. Open access fee: Open access (OA) refers to the way that the author chooses to let readers read for free when publishing a paper. Open access journals usually charge authors a certain fee to make up for the publishing cost. These fees may include article processing fee (APC), article reading fee (ARF) or subscription fee.
3. Research funds: Some journals will set up research funds to fund research projects in specific fields. Authors can apply for these funds to pay for publishing. To apply for research funding, it is usually necessary to submit detailed research plans and budgets, as well as research results related to the project.
4. Sponsorship and donation: Some periodicals will accept sponsorship and donation from enterprises or individuals to support their publishing activities. These sponsorships and donations can be used to pay part or all of the publishing costs, or to set up scholarships, bonuses and other incentives.
5. Support from academic institutions: Some academic institutions will provide financial support for their members to publish SCI papers. Such support may include direct payment of publication fees, provision of research funds or reimbursement of open access fees.
In a word, the calculation method of SCI manuscript fee varies from journal to journal, which may include publishing fee, open access fee, research fund, sponsorship donation, academic institution funding, etc. The author should fully understand the relevant expenses when selecting periodicals and make appropriate choices according to his own economic situation and research needs.
