专利分析视角下我国集成电路产业“卡脖子”问题研究

A Study on the Bottlenecks Technologies of Integrated Circuit Industry in China from the Patent Analysis Perspective

[目的]剖析当前我国集成电路发展的主要问题,提出技术创新的对策建议。[文献范围]53篇学术论文、行业研究报告和新闻报道,IncoPat专利数据库。[方法]综合运用文献调研、专利分析、专家研判多种方法,围绕集成电路产业链的材料、设计、制造与封测四个环节,开展技术自给能力分析与国际差距对比研究。[结果]我国在集成电路材料领域的高价值专利占比持续攀升,设计领域核心技术积累不足,制造领域技术创新稳步前行,封装与测试领域创新效能降低。[局限]专利检索策略不同得出的结果可能不同。[结论]我国集成电路领域存在“原始创新能力不足、核心技术积累匮乏、市场集中度不高”的问题,建议以开放式创新思维积极融入国际创新网络,突破潜在颠覆性技术实现关键技术自主可控,借助新兴产业蓬勃发展契机培育壮大国内市场。

[Objective]This paper aims to analyze the main problems in the current IC development in China and make recommendations for technological innovation.[literature Scope]53 documents including academic papers,industrial research reports and newspapers,and IncoPat patent database are studied.[Methods]In this paper,we use multiple methods such as literature research,patent analysis,and expert analysis to conduct the study,focusing on the key elements of the IC industry chain:materials,design,manufacturing,and packaging/testing.A comparative study on technological self-sufficiency and gaps to the international level is carried out.[Results]We found that the share of the high-value patents in the field of materials is rising;the accumulation of core technologies in the field of design is insufficient;the technology innovation in the field of manufacturing is being promoted steadily,and the efficiency of innovation in the field of packaging and testing is declining.[limitations]The patent analysis results obtained by different search strategies may be different.[Conclusions]The main problems in the China’s IC development are identified,including "insufficient capacity for original innovation,lack of core technology accumulation;and low market concentration".We recommend more active participation in the global innovation network with open and innovative thinking,striving for breakthroughs in potential disruptive technologies and ensuring the safety of key technologies,and taking the opportunity of emerging industry development to cultivate and expand the domestic market.
