摘　　要：[目的/意义]既有技术资源的丰富性及行业先发优势,使部分国家和企业占据了技术领先地位。提出核心技术发现与国内外企业技术差距识别方法,能够为我国企业探寻技术突破机会提供借鉴。[方法/过程]根据产品组件构成关系,构建“产品—组件—企业—专利”四维关系图,在技术网络性和技术重要性的基础上挖掘产品核心技术,根据企业在核心技术领域的“技术领域份额”指标对比国内企业与国外企业之间的技术差距,并应用手机摄像头产品2011—2021年专利数据进行实证分析,提出手机摄像头产品各组件的核心技术及国内外技术差距。[结果/结论]我国在对焦马达、保护膜、红外滤光片和镜头镜片领域与国外企业技术差距较大,而在图像传感器和线路连接基板领域占据优势。[Purpose/significance] Due to the abundance of existing technical resources and the industry’s first-mover advantage, some countries and enterprises form the industry’s technical barrier.This paper puts forward the method of detecting the core technology and identifying the gap between domestic and foreign technology, which may provide reference for Chinese enterprises to seek technological breakthrough opportunities.[Method/process] According to the product components, the paper builds four dimensional diagram(product-component-enterprise-patent),and mines products’ core technology on the basis of network-performance of technology and importance of technology.Then the paper identifies the technology gap between domestic enterprises and foreign enterprises based on TSA(Technology Share in the Area).Finally, the patent data of phone camera products from 2011 to 2021 are applied to empirically analyze the core technology of each component of phone camera products and the technology gap at home and abroad.[Result/conclusion] There is a big gap between Chinese and foreign enterprises in the fields of focusing motor, protective film, infrared filter and lens, while in the fields of image sensor and circuit connection substrate, Chinese enterprises has advantages.
