Abstract: Abstract: The construction of “Double First Class” is an important strategic deployment for China’s higher education reform. Since its implementation in 2017, the central and local governments at all levels have provided a large amount of resource support for selected universities, which has had a significant impact on the quantity and quality of scientific research work in universities. Use the double difference research model to compare and analyze the panel data of two equal time periods (2011-2021) before and after the launch of the “Double First Class” construction, and explores the impact of the first round of “Double First Class” construction on the scientific research work of 107 comprehensive and science and engineering universities from the two dimensions of the quantity and quality of scientific research output of universities. The research results indicate that the “Double First Class” policy has achieved significant construction effects in both promoting the quantity and improving the quality of scientific research output in universities; In addition, the study further found that the construction of “first-class disciplines” has formed significant positive spillover effects in the first round of construction through policy demonstration effects and local supporting incentives, especially in quality dimensions such as highly cited papers, top 1% papers, and the Category Normalized Citation Impact. The catching up speed of non-selected universities has exceeded that of experimental group universities. The paper recommended to better leverage the systematic impact and driving role of the “Double First Class” construction on national higher education, strengthen top-level policy design, deepen the reform of higher education evaluation in the new era, and promote the realization of the strategy of building a strong education country at a high level.

摘要： 摘要：“双一流”建设是我国高等教育改革的重要战略部署，自2017年实施以来中央和各级地方政府为入选高校提供了大量资源支持，对高校科研工作的“量”与“质”都产生了重要影响。运用双重差分（DID）研究模型，将“双一流”建设启动前后两个同等时间周期（2011-2021年）的面板数据进行比较分析，从高校科研产出数量与质量两个维度，探究了第一轮“双一流”建设对107所综合性和理工类高校科研工作所产生的影响。结果表明，“双一流”政策在促进高校科研产出数量与提升高校科研产出质量双重维度都取得显著建设成效；此外，进一步研究发现，“一流学科”建设通过政策示范效应和地方配套激励，在首轮建设中形成了显著的空间溢出效果，特别是在高被引论文、前1%顶尖论文、学科规范化引文影响力等质量维度上，非入选高校的追赶速度反超实验组高校，有效推动了高等教育系统科研产出的整体质量跃升。面向未来，建议更好地发挥“双一流”建设对国家高等教育的系统性影响与带动性作用，加强政策的顶层设计、深化新时代高等教育评价改革，高水平推动实现教育强国战略。
