摘 要:[目的/意义]打破聚类分析法关系分析的固有模式,从关键词共现网络的结构出发,探讨关键词网络位置对技术间关联关系的影响。[方法/过程]基于ESI数据库2017年5月的更新数据,以电子信息领域的高影响力论文为研究对象,在对该领域进行宏观分析的基础上,依据结构洞和桥结构两种媒介角色理论,基于关键词共现网络分析电子信息领域内各技术的媒介角色,识别各技术之间的内在关联。[结果/结论]研究结果表明,优化研究、智能电网、功率控制、非线性系统、时间延迟、稳定性、同步技术等技术的媒介作用较重要,与多种技术存在关联,对电子信息领域的技术发展有至关重要的作用。媒介角色理论从结构角度出发,将微观的个体间关系与整个网络的宏观结构相结合的分析思路为技术间关联关系的探讨提供了新的视角。[ Purpose/significance] Breaking the inherent model of the cluster analysis, this paper discusses the influence of network location on the relationship between technologies, starting from the network structure. [ Method/ process] Based on the updated data of the ESI database in May 2017, this paper takes the top papers in the research field of Engineering, Electrical & Electronic as the object. On the basis of the macroscopic analysis, this paper analyzes the media roles of each technology based on the theory of Structural Holes and Brokerage roles in the keyword co-occurrence network to identity the internal relationship between each technology. [ Result/conclusion] The research resuh shows thal the technologies of optimization, smart grid, power control, nonlinear system, time delay, stability, synchronization are more important as the media role, and con'elate with a variety of technologies. The theory of Structural Holes and Brokerage roles provides a new perspective for the discussion of the con'elation between technologies because its analysis idea which analyzes from the point of structure and contacts the micro-individual relationship with the macro-structure of entire network.
