Research On The Current Status Of Integrated Circuit Technology Development In My Country Based On Patent Measurement And Social Network Analysi

In the information age,integrated circuit is an important cornerstone of electronic information engineering,plays an important role in the development of national high-tech industry,and supports the development of national economy.However,at present,China has a high degree of dependence on overseas integrated circuit technology,and the "ZTE Incident" and Huawei’s case of being sanctioned by the US government have exposed the current situation where China is still constrained by high-tech,with a "bottleneck" phenomenon.At the same time,with the development of economic globalization,integrated circuit technology has been widely penetrated into various fields,especially in cloud computing and the Internet of Things,The 5G industry and other industries have an urgent demand for integrated circuit technology,so it is urgent to attach importance to the development of integrated circuit technology in China.Integrated circuit technology has become a research focus for research institutions in various countries.Therefore,it is necessary for research institutions and researchers in the field of integrated circuit technology in China to understand the current research status in other countries and China,and actively explore the strategic layout of integrated circuit technology development in ChinaThe article first analyzes the patent data of global and Chinese integrated circuit technology,mainly analyzing the geographical location of patent applications,information of important applicants,and related technologies.The analysis results are presented in a visual way,and the current status of global integrated circuit technology and Chinese integrated circuit technology is understood in a clear and intuitive way from the perspective of patent measurement,Clarify the international position of China’s integrated circuit technology.And based on rough set theory,a core patent comprehensive index system is constructed for five patent indicators in China’s integrated circuit technology patent selection,including the number of claims,the number of patent citations,and the number of patent literature pages.Based on the CICP value,core patents are identified to grasp the layout of China’s integrated circuit technology core patents.Based on patent data with authorized legal status,a social network analysis is conducted on China’s integrated circuit technology patents.The main focus is to construct a cooperative applicant relationship matrix and a technical cooperation relationship matrix for patent applicants and patent classification number information,respectively.The social network analysis method is used to analyze the overall social network,network centrality,and structural hole analysis Core edge analysis explores the overall cooperation network of integrated circuit technology in China,as well as the important innovation entities and research and development priorities of this technology.Finally,based on the analysis results and current technological situation,the overall situation of global integrated circuit patent applications and the development characteristics of integrated circuit technology in China are summarized.Relevant development suggestions are proposed for the development of integrated circuit technology in China: increasing the number of patents while improving the quality of patents,strengthening different innovative entities,achieving the integration of integrated circuit technology industry,academia,and research,strengthening cooperation between enterprises,and strengthening information resource exchange Establish corresponding intelligence teams to promptly monitor new developments in research and development.
