Peking University Institute of Economics and Guanghua School of Management will no longer recruit in-service doctoral students in principle from this year. Professor Zhu, deputy dean of Guanghua School of Management, Peking University, said that the most important thing is to ensure the quality of doctoral education. Through several years' practice, we deeply realize that working doctors do not have enough time and energy to complete this process, and it is difficult to complete their studies. Doctoral students have to take dozens of credit courses, which are very strict, especially economic management courses. You can't pass the qualification examination if you don't attend class. An example of a working doctoral student is a government official. In order to obtain government resources, some schools hope to have a good relationship with the government. If government officials want to study for a degree, they may be flexible. Another situation is that some schools are short of money, so they may want entrepreneurs to study for degrees to get some sponsorship. Another situation is that some celebrities in the society recruit them to study for degrees, which can improve the visibility of the school. These phenomena of trading power and money damage academic dignity. Professor Wen Rumin, director of the Chinese Department of Peking University, said that the Chinese Department has never recruited in-service doctoral students outside the school in recent years, just to resist this unhealthy trend. Nowadays, students who are working at school basically have no classes and have no time to attend classes. It is said that the secretary has been sent to class. Finally, make a paper casually and put on a doctor's hat. He said, "one size fits all" may wronged some truly talented people who can't leave their jobs, resulting in their losing the opportunity to study for a doctorate. But this is only an individual loss, which is fair in terms of the overall interests of society. In the future, if the atmosphere is good and there is an effective management mechanism, a more flexible approach will not produce too many side effects.
