As the second author of a paper, he is usually responsible for the authenticity, accuracy and legality of the content of the paper. If there are academic misconduct such as plagiarism in the paper, the second author also needs to bear the corresponding responsibility. The specific responsibility allocation and degree of commitment need to be judged and handled according to different situations and actual conditions.

When academic misconduct occurs, the second author may be held indirectly responsible. However, academic misconduct involving the signature of the paper, if the authenticity of the second author is wrong, the second author will bear the same main responsibility as the first author.

In the process of academic research, relevant researchers should supervise each other to ensure the scientificity and legitimacy of paper creation.
