硬科技是国家科技竞争力的核心载体、产业升级的底层动力、经济高质量发展的压舱石，以及国家安全的战略屏障，近几年逐渐成为研究的热点。以“硬科技”为主题，选取CNKI核心期刊数据库近十五年的中文文献、借助CiteSpace6.4R1软件生成发文作者、机构、研究热点及趋势的可视化知识图谱。发现近五年的研究热度显著提高，但缺少有引领作用的核心作者群和规模化研究机构，研究热点集中于技术创新从基础突破走向产业化落地、硬科技企业培育以及认定标准、适配硬科技成长规律的金融生态构建、人工智能推动硬科技企业转型升级等方面。智能化转型、耐心资本、政策赋能、跨域融合是硬科技领域未来的研究趋势。

As the core carrier of national scientific and technological competitiveness, the underlying driving force for industrial upgrading, the ballast stone for high-quality economic development, and the strategic barrier for national security, hard tech has gradually become a research hotspot in recent years. Taking “hard tech” as the theme, Chinese literatures from CNKI core journal databases in the past 15 years were selected, and visual knowledge maps of authors, institutions, research hotspots and trends were generated with CiteSpace 6.4R1. It is found that the research enthusiasm has increased significantly in the past five years, but there is a lack of leading core author groups and large-scale research institutions. The research hotspots focus on the industrialization of technological innovation from basic breakthroughs, the cultivation and identification standards of hard tech enterprises, the construction of financial ecosystems adapting to the growth law of hard tech, and the transformation and upgrading of hard tech enterprises driven by artificial intelligence. Intelligent transformation, patient capital, policy empowerment, and cross-domain integration are the future research trends in the field of hard tech.
