Abstract: Original innovation is the driving force for the development and progress of science and technology, and an important factor in determining the success or failure of science and technology and even economic competition among countries. China has always taken the enhancement of original innovation ability as a major strategy for national science and technology development in the new era. This paper focuses on the original innovation policy documents issued by the state in the context of the innovative national strategy (2006-2019), and through the establishment of the PMC evaluation index model and topic model, it evaluates and analyzes China's original innovation policy in three dimensions: the overall quality, the distribution trend of indicators and the evolution of topics. The results show that, in the context of the innovation-oriented national strategy, the original innovation policies are rich in types, comprehensive in content, mainly encouraging and guiding policies and focusing on innovation resource supply policy tools. However, there is still room for improvement in the supervision and evaluation, the coverage and implementation, and the role of guiding the transformation of innovative achievements. In view of the existing problems of the national original innovation policy under the background of the innovation-oriented national strategy, this paper proposes relevant suggestions for our government to formulate and implement the original innovation policy more scientifically and effectively.

摘要： 原始性创新是科学技术发展与进步的源动力，是决定国家间科技乃至经济竞争成败的重要因素，我国一直把增强原始性创新能力作为新时代国家科技发展的重大战略。本文围绕创新型国家战略背景下（2006-2019年间）国家出台的原始性创新政策文件为研究对象，通过建立PMC指数模型与主题模型，从政策整体质量效果、指标分布态势和主题演化规律三个维度对我国原始创新政策进行评价分析。结果发现，在创新型国家战略背景下国家发布的原始性创新政策类型丰富、内容全面，以鼓励引导型政策为主，重点围绕创新资源供给政策工具展开，但在政策的监督评估、政策覆盖面和实施力度、引导创新成果转化作用等方面仍存在需要完善的空间。针对创新型国家战略背景下国家原始性创新政策的现存问题，为我国后续更加科学有效地制定与实施原始性创新政策提出相关建议。
