Improvements in productivity based on co-authorship: a case study of published articles in China. Scientometrics, 85(2), 463-470. **Keyword** - ==Abstract== 在中國的科學技術研究領域,較高關係資本的研究者,也有較高的知識(期刊論文發表)生產力。 越多共同發表的期刊論文,研究者越成功(發表越多期刊論文)。不論是國內或國際的共同發表都與研究者個人的學術生產力正相關。 == Content == * 資料來源: ** 1998-2007 obtained from the Statistical Yearbook on Science and Technology in China ** ISI SCI expanded database ** 抽樣 240 觀察(不知道是論文或是研究者數量) * 邏輯 ** 原始生產力函數(Cobb-Douglas functional)://P(K,L) = bKαLβ// \\ //P// = 總生產量 total production, \\ K = 資本投入 capital input, \\ L = 勞動投入 labor input, \\ b = 總生產因子 total factor production, \\ α 與 β 是資本與勞動產出的彈性係數。 ** 學術生產力函數:Publication = //F(K)A//(RI, KB, COD, COI) \\ F(K) = 研究支出 is research expenditure on higher education, \\ A = 知識生產力 a group of knowledge productivities \\ RI = 研究者知識生產力強度 knowledge productivity of researcher intensity \\ KB = 出版國際論文數量 \\ COD & COI = 國內共同發表關係資本 與 國際共同發表關係資本 per capita domestic co-authorship capital and per capita international co-authorship capital == Note == 沒有交代生產力各項參數的定義與實際意義。如,如何量化「更高教育程度」。以及各參數間在實際意義上互相涵蓋並導致重複計算的問題(總論文發表數必然涵蓋共同作者出版的數量)。抽樣的學術領域差異也未交代。 == Metadata/Backlinks == {{backlinks>.}} {{tag>scientometrics}} **file link** - [[google.s>cho c. hu m. liu m. 2010 . improvements in productivity based on co-authorship|Google Schloar]], [[xxcfile>cho c. hu m. liu m. 2010 . improvements in productivity based on co-authorship|XXC]]
