The Influence of Interdisciplinary Dissertation Research on Delayed Graduation for Doctoral Students:Analysis Based on the National Survey of Doctoral Graduates
Interdisciplinary dissertations are an important way for promoting interdisciplinary academic training of doctoral students,but interdisciplinary research generally has the characteristics of high challenge and long cycle.Doctoral students conducting interdisciplinary dissertation research may face higher risks of delayed graduation.Based on the analysis of data from 2022 National Survey of Doctoral Graduates,it found that interdisciplinary dissertation research brings more pressure and require more time cost to doctoral students,and have a significant positive effect on their probability of delayed graduation.In terms of heterogeneity of the effect,interdisciplinary dissertation research is more likely to increase the risk of delayed graduation for doctoral students in natural science or with single disciplinary backgrounds.Based on this,it is recommended to provide the total process and multi-dimensional support for interdisciplinary doctoral dissertations.By providing delayed project funding and flexible school system,it aims to assist reasonably delayed doctoral students in completing high-level,long-term interdisciplinary research.And we should focus on supporting interdisciplinary research for natural science doctoral students and actively recruit students with interdisciplinary educational backgrounds.
