First of all, from the purpose, the preliminary examination mainly examines the format, content and logic of the paper to ensure the basic quality of the paper and meet the requirements of the journal. The final evaluation is to evaluate the academic value, innovation and depth of the paper in order to ensure the academic level and influence of the paper.
Secondly, from the content point of view, the preliminary examination mainly focuses on the form of the paper, including whether the structure, language and quotation of the paper are standardized, whether the theme of the paper is clear and whether the argument is sufficient. The final evaluation pays more attention to the content of the paper, including whether the research method of the paper is scientific, whether the data is accurate and whether the conclusion is reasonable.
Thirdly, from the standard point of view, the standard of preliminary examination is relatively loose, mainly depending on whether the paper meets the basic requirements of the journal. But in the end, the standard of peer review is stricter, which requires not only that the paper meets the requirements of journals, but also that the paper has certain academic value and innovation.
Finally, from the process point of view, the preliminary review is usually carried out by editors or experts of periodicals, and the process is relatively simple and fast. The final audit is usually carried out by the editor-in-chief of the journal or external experts, and the process is relatively complicated and rigorous.
Generally speaking, the preliminary examination and final examination of a thesis are aimed at ensuring the quality and academic level of the thesis, but they are different in purpose, content, standard and process.
