There is no uniform regulation on the consequences of not publishing a doctoral thesis for six years, and the requirements of each school are different. Judging from the current situation of doctoral thesis publication in China, long-term non-publication of the thesis will generally lead to delayed graduation, and in serious cases, the doctoral diploma will not be obtained.

For example, Dr. Liu Chunyang of China University of Science and Technology has not published a paper for six years, and his postgraduate degree is five years. Liu Chunyang should have received his doctorate in June 20 17, but he did not meet the requirements for doctoral graduation, so he delayed his graduation during his doctoral study.

The Guiding Principles for the Revision of Doctoral Degree Standards of China University of Science and Technology stipulates that the requirements for the scientific research achievements awarded the doctorate in geochemistry are: "Graduate students are the first authors (excluding the signature of the tutor), and our institute (School of Earth and Space Sciences, China University of Science and Technology) is the first signer.

Publish (or be admitted to) research academic papers related to dissertations "and" at least one English article must be published (the influence factors are not limited). The document also stipulates the continuous study period of master's and doctoral students: "The study period is generally five years, of which the doctoral study period is not less than three years.

Tutors can adopt flexible academic system according to the actual situation, and the longest study period of doctoral stage is no more than 6 years (including suspension). "This is very important.
