中文摘要 中文摘要 高新技术企业创新是我国掌握核心科技的“破局之要”。高新技术企业知识产 权保护保障了企业创新主体的权益，激励企业进行持续的创新活动，在提升企业 创新绩效方面作用明显。本文在文献梳理及理论推导的基础上，以我国 30个省、 自治区、直辖市 2009-2020年的高新技术企业数据为实证样本，检验我国高新技术 企业知识产权保护对创新绩效的直接影响效果，并探索 R&D投入在两者关系中发 挥的中介效应，从而厘清高新技术企业知识产权保护对创新绩效的传导路径和作 用机理。实证研究结论表明：高新技术企业知识产权保护强度的提高能够促进创 新绩效的提升；高新技术企业提升知识产权保护水平能够有效促进研发经费投入 和研发人员投入，进而提升企业创新绩效，即 R&D投入发挥中介作用；高新技术 企业知识产权保护对创新绩效的影响存在一定的区域性差异。根据研究结果，本 文结合高新技术企业实际情况给出了对策建议：高新技术企业与相关部门共筑良 好的外部创新环境；强化企业内部知识产权保护意识；完善企业内部知识产权保 护体系；制定差异化的知识产权保护策略；加大企业 R&D投入力度。本研究为高 新技术企业相关部门制定知识产权保护策略、促进企业创新发展提供了有益启示。 关键词：高新技术企业；知识产权保护；创新绩效；R&D投入 -I- 黑龙江大学硕士学位论文 Abstract Innovations in high-tech companies are the “key to breaking the ground” for China to master basic science and technology. Intellectual property protection for high-tech firms protects the rights and interests of subjects of corporate innovation, encourages firms to engage in ongoing innovation activities, and plays a clear role in improving firm innovation performance. This paper draws on literature combing and theoretical derivation to take as an empirical sample data on the direct impact of the intellectual property protectionof high-tech firmsin 30 provinces,autonomous regions, and municipalities directly under the central government from 2009 to 2020 on innovation performance in China, and explores the mediating effect of R&D investment in the relationship between the two, in order to clarify the transmission path and mechanism of protection of high-tech firms’ intellectual property on innovation performance. The results of empirical research show that improving the intensity of intellectual property protection for high-techfirms can promote improved innovationperformance; By improving the level of intellectual property protection for high-tech companies, R&D investments and investments in R&D personnel can be effectively promoted, and then promote the innovation performan
