The requirement of duplicate checking rate of published papers varies with the type of papers and the level of journals. Generally speaking, the duplicate checking rate of published papers of periodicals is below 5%~30%, that of ordinary periodicals is below 20%~30%, that of national periodicals is below 10%~ 15%, and that of core periodicals is the most stringent, and the duplicate checking rate is usually required to be between 5% and 65438.

For papers with different titles, the requirements are different. Generally speaking, the examination rate of primary thesis topics < 30% is qualified; Intermediate/provincial papers with duplicate checking rate < 25% are qualified; Senior/national papers with duplicate checking rate < 20% are qualified; The duplicate checking rate of papers in advanced/core journals is less than 8% ~ 15%.

It should be noted that different journals and institutions may have different requirements for duplicate checking rate of published papers. Therefore, it is necessary to understand the specific requirements and standards of journals or institutions in order to better complete the writing and revision of papers. At the same time, paper duplication checking is only a preliminary screening of paper quality, and it can not completely guarantee the quality and academic value of the paper. Therefore, when writing a thesis, we need to pay attention to academic integrity and norms, and abide by academic ethics and laws and regulations in order to obtain better academic results.
