Correspondents often refer to the general person in charge of the project, who is responsible for the funding, design, writing and check of the project. He is also a contact person for articles and research materials. Most importantly, the correspondent is responsible for the reliability of the article.

The first author is generally the researcher who has made the greatest contribution to this work. This author not only has the most important charts (that is, physical contributions), but also is the author of the first draft of the article (that is, the contribution of intelligence to this article).

2. Different in nature

The correspondent is the head of the article.

The first author is the executor of the article.

3. Ownership of results

Generally speaking, the author of a communication and the first author are the same person. But as far as intellectual property rights are concerned, the research results belong to the communication author, not the first author.

"Three Admits and Three Negations" in Academic Evaluation System

Zhao, a member of the Chinese People's Political Consultative Conference (CPPCC) and director of the National Nanoscience Center, said, "At present, there are three ways to identify scientific research achievements in China: only the first author, only the first author unit, only the correspondent author, but not the non-first author, non-first author unit and non-correspondent author. This is a short-sighted and narrow-minded approach. "

Objectively speaking, for the evaluation of scientific research talents, the ranking and quantity of papers and the grade of published periodicals are indeed an intuitive and easy-to-judge standard. This standard has also played its positive role, such as making the talent evaluation standard objective and not giving room for black-box operation.

However, with the strengthening of the administration of colleges and universities, the standards are distorted in the implementation, which seriously hurts the enthusiasm of researchers and stifles the vitality and motivation of innovation. And "three denials" is a typical phenomenon.
