Hello, there are no clear and specific provisions in relevant laws, but in practice it is generally believed that teachers have no copyright. According to the regulations of degree management, students' papers must have an "original explanation", which means that the students created them independently. Unless the paper is plagiarized, its copyright belongs to the students themselves.

In practice, there are many cases in which tutors use students' papers. If the tutor can't produce evidence to prove that he has the same creative agreement with the students and has paid direct and substantial creative labor, then the tutor will infringe the copyright of the students.

In addition to the "original statement", there is also a "power of attorney for copyright use of dissertation" in front of the text of college students' dissertation, which is signed by students and tutors. Some experts believe that this shows that the school has regarded the copyright of the paper as a student's, and the signature of the tutor has played an informed role. However, due to the needs of social public interests, it is beneficial to maximize the utilization efficiency of academic resources and inherit academic traditions to reasonably limit the author's personal rights and allow schools to use dissertations in a certain range. In addition, tutors and schools, after all, provide some help for students' thesis writing. If students' papers are published, students should show their tutors' works in appropriate positions.
