摘要
随着我国博士生规模的不断扩大,已婚博士生已经成为了不可忽视的群体,他们既面对着科研和家庭的双重压力,又感受着家人的支持与陪伴,但鲜少有严谨的实证研究能够阐明清楚结婚是否影响博士生科研发表。为此,本研究基于2016年首都高校学生发展状况调查博士生数据,采用倾向得分匹配法控制样本自选择内生性从而估计婚姻对博士生科研发表的影响。研究发现,结婚对博士生科研发表有显著的正向影响,相比未婚博士生,已婚博士生论文发表总篇数高出0.4篇,以第一作者或通讯作者发表的论文数高出0.47篇;结婚对博士生科研发表的影响主要集中于耗费个人精力和时间较多的以第一作者或通讯作者发表论文数上;性别差异上,结婚对男性博士生科研发表不具有显著影响,但对女性博士生科研发表有显著的正向影响,相比未婚女博士生,已婚女博士生论文发表总篇数高出0.75篇,以第一作者或通讯作者发表的论文数高出0.71篇。
With the continuous expansion of the scale of PhD students in China,married PhD students have become a group to be reckoned with.The students are facing the pressure from both academic research and family while enjoying the support from and company of their families.As of now,few empirical studies have clarified whether marriage affects the PhD students when they publish research papers.Therefore,based on the data of the PhD students from a survey on the student development at Beijing-based universities 2016 and with the application of the propensity score matching method to control the endogeneity in sample auto-selection,this study estimates the impact of marriage on the success of the PhD students in publishing papers.The study finds that marriage has a significant positive impact on paper publishing by PhD students.In comparison,the total number of the papers published by married PhD students is 0.4 more than those by unmarried PhD students,and the number of papers published by married PhD students as first author or corresponding author is 0.47 more than those by unmarried PhD students.The influence of marriage on the successful paper publishing by PhD students is mainly demonstrated by the number of the papers published by them as the first author or corresponding author,which cost more personal energy and time.When it comes to gender,marriage does not have significant impact on the successful publishing of research papers by male PhD students,but the impact on the successful publishing of research papers by female PhD students is obvious positive.In comparison,the total number of the papers published by married female PhD students is 0.75 more than those by unmarried female PhD students,and the number of papers published by married female PhD students as first author or corresponding author is 0.71 more than those by unmarried female PhD students.
