Abstract：With the rapid development of the global economy and the continuous promotion of scientific and technological innovation，technological innovation has become an important force to promote economic growth and enhance industrial competitiveness.As a key field of technological innovation，it is particularly important to improve the innovation eficiencyof patent一intensive industries.Based on the patent一intensive industry data from 20l2 to 2O22，combined with the Statistical Classification of Pa. 1 tent一Intensive Industries （2Ol9）and China Science and Technology Statistical Yearbook，this paper screened eight patent-intensive industries as the research object，and used the double fixed一effects model to investigate the relationship between the intensity of governmental R^amp;.D inputs，the intensity of corporate Ramp;D inputs，and the intensity of foreign R^amp;.D inputs and the innovation efficiency of patent一intensive industries.The relationship between government Ramp;D investment intensity，enterprise R^amp;.D investment intensity and foreign Ramp;D investment intensity and the innovation efficiency of patent-intensive industries is analyzed empirically by using the double fixed efect model，and the moderating roleof intellectual property protection level is explored.The results of the study show that there isa positive U- shaped relationship between government Ramp;D investment intensity，enterprise R^amp;D investment intensity and foreign R^amp;.D investment intensity and innovation efficiency of patent一 intensive industries，and the level of intellctual property protection can strengthen the positive U- shaped relationship between enterprise Ramp;D investment intensity and innovation efficiency. The level of intellectual property protection can strengthen the positive“U”-shaped relationship between Ramp;D investment intensity and innovation efficiency of enterprises.Therefore，government R^amp;.D investment should focus on optimizing the structure and improving the eficiency，comprehensively strengthen the protection of intellectual property rights while effectively guiding foreign R^amp;D investment，while enterprises should pay more attention to the combination of technology accumulation and market demand. Key Words：Patent-Intensive Industries；Innovation Efficiency; Ramp;D Investment Intensity；Intellectual Property Protection Levels

随着全球经济格局的深刻变革，技术创新已成为各国经济发展的核心动力。从“资本驱动”到“创新驱动”，经济发展的核心模式正经历由传统工业型经济向科技驱动型经济转型。在这一背景下，知识产权密集型产业的发展已成为各国经济发展战略的重要组成部分。根据美国商务部和专利商标局在2012年发布的《知识产权与美国经济：产业聚焦》报告，知识产权密集型产业被定义为高度依赖创新和专利保护的行业，此类产业在全球范围内得到了高度重视，并成为推动国家经济转型与升级的重要动力。

在推进经济转型的过程中，我国逐渐认识到知识产权密集型产业在推动经济高质量发展中的关键作用。随着中央及地方政府对专利密集型产业政策支持力度的不断增强，知识产权已成为我国发展战略的重要资源。《知识产权强国建设纲要 （2021-2035 年）》提出，“到2035年，我国知识产权综合竞争力跻身世界前列，知识产权制度系统完备，知识产权促进创新创业蓬勃发展，全社会知识产权文化自觉基本形成，全方位、多层次参与知识产权全球治理的国际合作格局基本形成，中国特色、世界水平的知识产权强国基本建成”。因此，提升知识产权保护水平和创新能力，对于我国经济高质量发展具有重要的战略意义。国家统计局和国家知识产权局发布的最新数据显示，2023年中国专利密集型产业的总产值已达到168713亿元，占国内生产总值（GDP）的13.04% ，较上年增长了0.44个百分点，这一数据进一步验证了专利密集型产业在推动我国经济增长中的关键作用。……
