First of all, the review targets are different. External audit is usually conducted by the editorial department of the journal or special reviewers, who are usually experts in this field and evaluate the quality, innovation and scientificity of the paper. The peer review is conducted by the journal editorial board or senior editors, who make a more in-depth and comprehensive evaluation of the overall quality and academic value of the paper.
Secondly, the purpose of review is different. External audit is mainly to ensure the basic quality of the paper, including language expression, data accuracy, research methods and so on. If the external audit passes, the paper will usually be accepted and go to the next stage. The summary is to further confirm the academic value and influence of the paper, including its innovation, research depth and theoretical contribution. If the paper is approved, it will usually be officially published.
Finally, the content of the review is different. External audit mainly focuses on the specific content of the paper, including research methods, data analysis and interpretation of results. The review pays more attention to the overall structure and logic of the paper, including whether the introduction, literature review, research methods, results discussion, conclusion and other parts are consistent and whether the theme of the paper is clear and prominent.
Generally speaking, external review and peer review are important links to ensure the quality of papers, but the emphasis and requirements are different. External audit pays more attention to the technicality of the paper, and evaluation pays more attention to the academic nature of the paper.
