我国航空发动机产业基础创新现状及提升建议 ——基于专利计量视角

Present Status and Suggestions of Aeroengine Industry Foundation Innovation in China: Patentometrics Perspective

摘要:

本文采用专利计量分析法对国内外航空发动机产业基础领域专利进行统计，对国内外创新现状从技术和市场两个维度进行比较分析。研究发现：中国在叶片制造等领域具备创新数量优势，轴承和超高强度钢等领域尚有空白；产学研主体创新活跃程度高，但合作比重低；专利数量优势逐渐显现，但影响力有待提高，存在转化率低和海外布局不足的问题。基于分析结果，总结中国航空发动机产业的“长板”和“短板”，提出面向需求加强协同创新、增强优势技术影响力、着力突破关键技术等对策建议。

Abstract:

Based on the statistical information of global patents of aeroengine industry foundation, this paper compares and analyzes the current situation of different countries in two dimensions of technology and market with patentometrics methods. The study discovers that China obtains numerical superiority in the areas such as blade manufacturing while leaving blanks in bearing and ultra-high strength steel, its applicant types contains industry, university and scientific institution with a low ratio of IUR cooperation, its innovation influence lacks despite numerical rising with a low rate of technology transfer and a nearly blank international patent portfolio. According to analysis results, the advantages and disadvantages of China’s aeroengine industry foundation innovation are concluded, the suggestions that demand-oriented collaborative innovation should thrive, advanced technologies should expand their reach and crucial technologies should make breakthroughs are put forward.
