Chinese core journals have relatively strict requirements for paper duplicate checking rate, which is generally between 5%- 10%.

The specific standards may vary according to the types of journals and papers. For the core journal papers of medicine, law and other majors, the duplicate checking rate may be lower, generally within 5%.

In addition, some core journals in China are relatively easy to publish, and the duplicate checking rate can be within 15%.

It should be noted that different core journals may have different requirements for repeated retrieval rate, but most core journals will take 5%~ 10% as the reference threshold.

Therefore, the author needs to read the submission guide or requirements of the journal carefully before submitting, understand the specific requirements of the journal for the duplicate checking rate of the paper, and make targeted amendments and improvements. At the same time, we should also pay attention to choosing a regular duplicate checking system to ensure the accuracy and reliability of duplicate checking.
