| Summary: | 碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 99 === The main purpose of this study was to explore the evolution and convergence of nanofibers based on patent citation network analysis. Besides, this study investigates the relationship between patent characteristic and citation network characteristic on nano-convergence.
This paper mainly collected patent information in the United States Patent and Trademark Office (USPTO) database. This study data consisted of 262 key patents in the nanofibers technology and further constructed a patent citation matrix; finally, UCINET software was used for nanofibers technology network analysis. Finally, hierarchical regression analysis are used to analyze the nano-convergence
The primary findings indicate that the convergence degree of nanofibers’ technologies with other technologies is low in current stage. Moreover, some of patent characteristics including “Reference citing”, “Claim”, “Patent Family”, “Foreign Patent”, and “Self-citation” have significant effects on Nanofiber convergence. “Degree”, “Closeness”, “Betweenness” in citation network characteristic has significantly positive effects on nanofiber-convergence.
