廠商在進行研發並透過吸收他人技術之知識,從而內化成為核心能力,並建構不同組合的技術能力;然而,如何辨識公司之間的技術優勢以進行技術之研發,為所有管理者的一個重要的經營議題。本研究從專利統計量觀點,透過檢索的專利資料以專利統計量的方式,使用專利後向引用分析,經由網絡中心性之指標,將其進行分組,得出知識中介者之角色,並建立中介者之間的專利引用網路以及相對專利引用傾向,以便測量技術之來源與移動方向,以及探討套筒行業廠商的產業技術優勢。最後,透過技術吸引力、相對專利優勢與技術相對地位三項專利統計量,分析套筒行業知識中介者公司的研發組合在產業間的優劣勢,使中介者的公司能夠有效監控自身的技術能力,並且瞭解公司的技術優勢以進行研發方向之調整。
Manufacturers invest in research and development, absorb the technical knowledge of competing operators, to become the core competencies, and further construct a different portfolio of technical capacities. However, how to identify the technical advantages of competing companies to carry on research and development of technical , is an important topic for business operations of managers. This study, from the perspective of patent statistics, examines retrieved patent information and formulates patent statistics to use patent backward citation, then group the information of the knowledge betweenness is obtained. The patent between the citation network and the relative citation propensity in order to measure the source of technology and direction of movement, explore the industrial technical competitive advantages of Socket Wrench Industry. Finally, using three patent statistics, namely technical attractiveness, technical relative position and relative patent advantages, this study analyzes the strengths and weaknesses of the research and development portfolio of knowledge betweenness of Socket Wrench Industry. Knowledge betweenness companies can effectively monitor their own technical capabilities, and understand the company's technological advantages to adjust the direction of R & D.
