出国留学对博士生能力发展的影响OA北大核心CHSSCDCSSCI

In the era of globalization and knowledge economy,the internationalization of higher educa-tion is constantly deepening and the scale of international flow of doctoral students is expanding.The ability development of doctoral students studying abroad has become a topic worthy of attention and discussion in the field of higher education.Based on the data of the 2019 Nature Global Doctoral Survey,the methods of ordinary least squares regression,propensity score matching and quantile regression were used to study the influence of studying abroad on the ability development of doctoral students.The empirical results show that studying abroad has a significant negative effect on the academic ability development of overseas doctoral students,and the negative effect shows a weakening trend with the increase of doctoral students'ability level.On the contrary,studying abroad has a significant positive effect on the general ability development of overseas doctoral students,while the positive effect shows a trend of strengthening first and then weakening with the increase of doctoral students'ability level.From the perspective of different countries,in China,the academic ability development of overseas doctoral students is better,but the general ability development is insufficient.On the contrary,in the United Kingdom and the United States,the general ability develop-ment of overseas doctoral students is better,while the academic ability development is lower.In addition,supervisor's guidance plays an important role in the overseas academic training of doctoral students.It is found that supervisor's guidance has a significant positive influence on the development of doctoral students'academic ability,and it can weaken the negative impact of studying abroad on the academic ability development of them.However,the main effect and moderating effect of supervisor's guidance on the general ability development of overseas doctoral students are not significant.It is suggested that university in China should optimize the doctoral cultivation model to improve the general ability of overseas doctoral students;the supervisor should transform their cultivation concept and adopt targeted training arrangements;overseas doctoral students also should clear their own development orientation and enhance the adaptability of cross-cultural learning.
