基于专利数据的中美新能源材料创新态势研究

Research on the Innovation Trend of New Energy Materials in China and the United States Based on Patent Data

从专利价值度、专利发展态势以及专利创新价值的视角出发,基于专利数据对中美新能源材料进行比较研究。研究结果显示:(1)中国新能源材料领域已经在创新规模、创新增速上实现了“弯道超车”,但在创新价值、高价值专利占比上仍处于劣势,呈现出“高量低质”的特点,且缺乏专利保护意识。(2)现阶段,中国新能源材料技术的发展主要集中在先进基础材料和前沿新材料领域,而美国以其先发优势,着重保持其在关键战略材料领域的优势。鉴于此,中国需要在继续保持自身优势领域的基础上,针对弱势材料领域,通过政策引领、创新激励等方式,缩短与美国的差距。

Based on the perspectives of patent value,patent development trend,and patent innovation value,a comparative study of new energy materials between China and the United States is conducted using patent data.Results show that:(1)Chinese new energy materials sector has achieved“overtaking on a bend”in terms of innovation scale and new patent application speed,but still lags behind in innovation value and the proportion of high-value patents,showing a“high quantity with low quality”feature and lacking patent protection awareness.(2)At present,China’s new energy materials technology is mainly focused on advanced basic materials and frontier new materials,while the United States,with its first-mover advantage,focuses on maintaining its advantage in key strategic materials.Therefore,China needs to continue to maintain its advantages in existing fields,and narrow the gap with the United States in its weak areas through policy guidance,innovation incentives,and other measures.
