Based on the value criterion on personal level of core socialist values, this paper makes a questionnaire survey of doctoral students in 35 universities in China from four dimensions:patriotism values, dedication values, integrity values and friendship values, and makes a comprehensive survey of the current value situation of doctoral students in China. The results show that, on the whole, the current level of doctoral students' values in China is optimistic, but there is still much room for improvement:the lack of political expression will of doctoral students, the different level of patriotism values in different age groups, the structural contradiction of dedication values, the construction of academic ethics, the inadequate initiative of friendship values. Therefore, it is necessary to stimulate the political expression willingness of doctoral students by establishing multi-channel political expression channels, and do a good job in inheriting and educating patriotism values of doctoral students; formulate research plans in combination with the interests of doctoral students, stimulate their intrinsic motivation for scientific research, and maintain a better value of devoting themselves to scientific research; strengthen the role of tutors in the process of morality cultivation through strengthening the construction of tutors' academic ethics and academic communities; stimulate the initiative of doctoral students' friendship values through friendly academic communities, and promote interdisciplinary exchanges and personnel training.
