比特幣是第一個加密電子貨幣，隨著近幾年比特幣風靡全世界，比特幣的研究日益增長，但多聚焦在比特幣的特定領域。本研究利用全球最大的索引資料庫之一Scopus，以敘述性分析、網絡分析與文字採礦等方法探討在Scopus中所有比特幣相關研究之文獻分析，提供一個從各面向了解比特幣發展的脈絡。分析的研究結果顯示在2013年後研究數量有顯著的增長，國家發表數量以美國為主，主要研究的子領域為資訊科技領域，財務商管領域次之。在網絡分析中作者耦合(author coupling)的研究結果顯示經常合作的作者群，並觀察其作者群研究領域，提供往後研究者可針對特定作者群搜尋其關鍵文獻;共被引分析(co-citation)的研究結果顯示共被引之文獻在特定領域具備相似性質，以利往後研究者了解比特幣文獻脈絡及族群性;作者關鍵字耦合(co-occurrences word)和共現字(co-word)針對作者關鍵字(Author Keywords)與KeyWords Plus主要出現的字詞類別為比特幣技術面和比特幣資訊科技，主要在探討的關鍵字是技術面的議題。後續又針對摘要做文字採礦並以BITCOIN為主題，挖掘與主題具有高度相關的關鍵字，並且提供關鍵字之符合議題和文獻資料。了解作者關鍵字、KeyWords Plus與摘要所挖掘出現的字詞能更有延伸性的了解熱門關鍵字的範疇，亦可以提供後續研究者在查閱文獻時能從更多面向的搜尋。本研究目的是為了進一步了解比特幣各領域的關係和探討的議題，透過挖掘作者、研究、引用文獻與關鍵字之關係，整理出重要議題，並提供相關文獻，給予想要進入該新興領域的研究者能更有廣度來了解比特幣和掌握議題，也可以給予致力已久的研究者從不同的角度來檢視該特定領域的議題趨勢。;Bitcoin is the first electronic money that allows online payments without financial institution. To further understand how the academia investigated this emerging discipline, research papers with keyword bitcoin during 2011 to 2017 were collected from the Scopus database in this research. The objectives of this study are to provided different angles to understand the development of bitcoin research by using visual analytics, network analysis and text mining. From the results of visual analytics, the number of bitcoin researches started to grow after 2013. Analytics also indicate that the most productive country regarding bitcoin research was the U.S., and the most published research subfields was computer science. From the result of network analysis, bitcoin literature can be classified into three categories that include “bitcoin transaction and information security”, “bitcoin optimization” and “bitcoin network protocol”. The purpose of this study also focused on revealing the important topics which were transaction, currency, peer to peer, international, nature, innovation, economic in Bitcoin by assessing the correlation between Author Keywords, Keywords Plus and keywords. Through our study, scholars may find a more extensive point of view to understand the literature of bitcoin and develop research topics.
