基于社会网络分析的我国芯片产业加权专利合作网络研究*

Research on Weighted Patent Cooperation Network of Chinese Chip Industry Based on Social Network Analysis

摘要:

芯片产业是现代产业体系中基础性、战略性和先导性的产业,基于合作专利数据研究芯片产业加权网络的结构特征,有助于揭示我国芯片专利合作网络的内在耦合机制以及互补机制,为决策者制定合理的产学合作政策和芯片产业发展战略提供理论依据。本文以中国芯片产业为研究对象,运用社会网络分析方法,通过构建芯片产业加权专利合作网络,从网络结构、关联性、社群和重要节点等方面,研究了芯片产业加权专利合作网络的结构特征。研究结果表明：中国芯片产业加权专利合作网络具有幂律分布的特性；企业在芯片产业的专利合作申请中占据主导地位,北京、上海和广东等经济发达地区是该网络节点的重要组成；度值较大的专利申请人呈现明显的连接偏好,节点的权重比度值增加的更快,网络具有同配性质；国家电网公司是该网络最为重要的节点,电子科大、台积电占据该网络中的重要位置。据此,本文对提升中国芯片产业发展提出了建议。

Abstract:

The chip industry is the basic, strategic and leading industry in the modern industrial system. Based on the data of cooperative patent, the research on the structural characteristics of the weighted network of chip industry will help to reveal the internal coupling mechanism and complementary mechanism of the cooperative network of chip patent in China, and provide a theoretical basis for decision makers to formulate reasonable policies and development strategies of the chip industry. By establishing a chip industry"s weighted patent cooperation network and applying social network analysis methods, the structure of Chinese chip industry"s weighted patent cooperation network is studied from the aspects of network structure, correlation, agglomeration subgroups and important nodes. The research results show that: Chinese chip industry weighted patent cooperation network has the power-law distribution characteristic; enterprises occupy a dominant position in the chip industry"s patent cooperation applications, and economically developed regions such as Beijing, Shanghai, and Guangdong are important components of the network node; Larger patent applicants show obvious connection preferences, the weight ratio of nodes increases faster, and the network is of the same nature; the State Grid Corporation of China is the most important node of the network, and the Electronic Science and Technology University and TSMC occupy important positions in the network. position. Based on the conclusion, this article puts forward suggestions for improving the development of Chinese chip industry.
