The main purpose of this associational study is to determine whether the most productive journals in library and information science are related positively to the most productive authors in the same field. A second purpose is to determine whether these same most productive journals are related positively to readability levels of articles contained in the journals.

本研究旨在探討1989至2008年間，台灣、香港、大陸地區工程類文獻作者之共同合作情形，透過兩岸三地被SCIE資料庫蒐錄之文獻數量，進一步觀察十四類工程學門中作者人數、作者合作對象、高產量機構及其合作對象、以及作者人數與文獻被引用次數間是否相關。 研究結果得知在十四類工程學科中，兩岸三地皆以免疫生物醫學工程之平均合作作者人數為最高，環境工程亦同樣在三地都有較高平均作者人數的表現，由此可見，免疫生物醫學工程及環境工程都是較多學者共同合作研究產出的學科。兩岸三地之多作者文獻比率皆在90%左右，單一作者文獻數較少。在高產機構方面，台灣則集中於台灣大學、成功大學、清華大學、交通大學，並發現台灣大學的研究者最常與同校研究者共同合作。此外，兩岸三地之跨國合作對象皆以美國為最多。最後探討作者人數與文獻被引用次數間是否相關，發現兩岸三地單一作者產出之文獻的被引用次數普遍較低，但皆無法明顯看出作者人數與文獻被引用次數間的關係。 本研究結果在為兩岸三地工程學門文獻之作者生產力提供一個概括呈現，以了解不同的工程學門間之差異，並協助高等教育評鑑對於工程領域的學術生產力概況有一背景瞭解，作為日後之評鑑參考。 / The purpose of this research is to discuss the degree of collaboration among engineering literature authors within Taiwan, Hong Kong, and Mainland China from 1989 to 2008. We use the quantity of literatures that are collected from Taiwan, Hong Kong, and Mainland China by the SCIE database to further observe the number of authors in fourteen engineering subjects, the people with whom the authors collaborate, the high production organizations and the people with whom they collaborate, and the correlation between the number of authors and the frequency of being cited. The findings are as follows. Biomedical engineering has the highest average number of author collaboration in Taiwan, Hong Kong, and Mainland China. Environmental engineering also has high average number of author collaboration in relation to other subjects in Taiwan, Hong Kong, and Mainland China. Therefore, we can see that immunity biomedical engineering and environmental engineering are the subjects that require more scholars to collaborate. The percentage of multi-author literature is approximately 90% in Taiwan, Hong Kong, and Mainland China. There are fewer sole-author literature. For high-production organization, the majority of author collaboration has higher concentration in National Taiwan University, National Cheng Kung University, National Tsing Hua University, and National Chaio Tung University in Taiwan. In addition, the researchers from National Taiwan University collaborate mostly with the researchers from the same university. In addition, Taiwan, Hong Kong, and Mainland China has the most international collaboration with the United States of America. Finally, we discuss the correlation between the number of authors and the frequency of being cited. The finding is that the sole-author literature in Taiwan, Hong Kong, and Mainland China has lower frequency of being cited in general, but we cannot find the correlation between the number of authors and the frequency of being cited. The findings of this research is to provide a general representation of literature author productivity in engineering subjects in Taiwan, Hong Kong, and Mainland China, to understand the differences in different engineering subjects ,and to assist higher education institute with background understanding in evaluating the academic productivity of engineering areas in the future.
