碩士 === 逢甲大學 === 科技管理研究所 === 97 === Aerospace and aircraft technology, structured by numerous cutting- edge basic sciences, needs support of plenty of industries. Most countries possessing advanced aerospace and aircraft technology also superiorly hold other non-military industries, such as automobile, information, communication industries, and so forth. This study mainly investigates how these cutting-edge technologies diffuse to the application of civil industry and still expand to totally different new technologies. In the past there were some papers utilizing patent citation to measure knowledge diffusion, this study will further explore the relationship between multi-generation patent citation and knowledge diffusion. This research employs each generation, concentration of assignee countries and technology proximity to present scope and rate of knowledge diffusion. This research takes Hughes Aircraft Company as a case study, and applies its related patents of Very Small Aperture Terminals to be research target. As the result of empirical analysis, these 21 patents successfully diffused to 33 countries and 115 varied technology fields. In addition, in the diffusion scope, every citation generation generate more extensive range of diffusion, and Japan is the most prompt country of absorbing knowledge in spite of US, but Taiwan and Korea is relatively backward.
