Strictly speaking, replication rate and repetition rate can be understood as the same concept in the publication of academic papers. Strictly speaking, the replication ratio directly affects the repetition rate. The higher the copy rate of a paper, the higher the repetition rate. The reproduction ratio refers to the ratio of the author quoting other people's literature without any modification.

2. In the writing of academic papers, we generally don't encourage such large-scale direct quotation. Large-scale direct quotation itself will increase the repetition rate of articles. Once the repetition rate of an article exceeds the safe range, the article will be identified as plagiarism, which is extremely unfavorable to the publication of the article and the author's personal development. Therefore, paper writing can quote other people's literature, but it needs to control the proportion, reduce invalid quotations and improve the originality of the article.

3. The high repetition rate is sometimes caused by the author's large-scale direct citation, and sometimes by the nonstandard citation of literature. In fact, when quoting literature, on the one hand, we should reduce the length of direct quotation, on the other hand, we also need to master certain citation skills. Skilled citation will not only lead to high repetition rate, but also improve the level and readability of the article. Of course, the use of any small skill is not as good as improving the originality of the article, and the repetition rate of originality will not be high, and the innovation of the corresponding article will also be improved.

4. Different publishing levels have different repetition rate standards. Generally speaking, the higher the value of a publication, the higher the requirements for articles and the lower the standard line of repetition rate. Ordinary journals may be lower than 30%, and core journals may need to be lower than 15% or even lower.
