技术壁垒环境下产业核心技术预见方法研究——以航空航天产业为例

Research on Foresighting Method of Industrial Core Technologies in the Environment of Technical Barriers——Taking the Aerospace Industry as an Example

中美贸易战以来,美国政府通过加强对中国的出口管制,设置了一系列技术壁垒。在此环境下,本文基于技术壁垒分析,采用专利对比分析法、词频逆文档法和内容分析法,找出中国航空航天产业劣势技术,然后进一步从微观层面竞争情报视角,结合美国出口管制清单深层次挖掘钳制中国航空航天产业发展、急需突破却受到技术壁垒的核心技术,尝试为产业核心技术预见提供一种崭新的视角和方法。

Since the Sino-US trade war,the U.S.government has set up a series of technical barriers by strengthening export controls.In this environment,based on the technical barriers analysis,using patent comparative analysis,Term Frequency-Inverse Document Frequency(TF-IDF)and content analysis method,the paper finds out the inferior technology of China s aerospace industry.Combined with the US commerce control list,the paper further excavates the core technical direction of suppressing the development of China s aerospace industry which urgently need to break through technical barriers from the perspective of micro-level competitive intelligence,and tries to provide a new perspective and method for the industrial core technology foresight.
