摘　　要：作为我国落实科教兴国战略的重要组成部分,自20世纪末以来推行的高等教育规模扩张政策对我国高等教育数量、质量与结构的历史演进态势产生深远影响。基于1996—2016年省级面板相关数据,采用双重差分模型(DID)解析高等教育规模扩张政策对大学科研产出水平的影响。研究结果显示:高等教育规模扩张政策能显著提升大学的科研水平,对其贡献度为35.1%—66.1%;高等教育规模扩张政策对提升大学科研产出存在显著递增效应,在2003—2006年、2007—2010年、2011—2016年三个时间段的贡献度分别达到55.1%、64.3%、74.6%;高等教育规模扩张政策对西部地区大学的科研产出水平具有显著提升作用,贡献度达149.6%,对中部和东部地区的影响则不显著。As an important part of China′s strategy of rejuvenating the country through science and education,the policy of expanding the scale of higher education since the end of the 20th century has had profound influences on the quantity,quality,and structure evolution of higher education in China.With the provincial panel data from 1996 to 2016,this paper delves into the influence of the policy of expanding the scale of higher education on the level of scientific research output of colleges and universities by using the difference-in-differences(DID)model.The results show that this policy can significantly improve the scientific research level of colleges and universities with a contribution rate of 35.1%-66.1%.It has a significant increasing effect on improving the scientific research output of colleges and universities,with its contribution rate reaching 55.1%,64.3%,and 74.6%in periods of 2003-2006,2007-2010,and 2011-2016,respectively.In the context of this policy,a significant improvement is observed in the level of scientific research output of universities in the western region of China,with a contribution rate being as high as 149.6%.By contrast,the influence of this policy is not significant in the central and eastern regions.
