First of all, "completely use the indicators and models of other people's papers and then analyze them yourself" is not plagiarism in theory, after all, there are differences. But this affirmation is very unwise, because at least we can synthesize the indicators and models of many literatures to improve the scientificity and credibility of our articles. Secondly, from the current literature, almost no articles directly apply other people's models and indicators, and will be adjusted according to their own articles. If you directly apply other people's models and indicators, it may mean that your research topic is consistent with the overall structure, which will increase the possibility of suspected plagiarism. Finally, the indicators and models of students' papers must be adjusted and determined according to the indicators and models of high-quality literature, and the original indicators and models of students are not convincing. However, it should be noted that references are not direct copies of documents. We must adjust the number of variables, measurement methods and model types according to our own research topics, and learn the skills of changing data intervals (years) and data intervals (regions).
