For the level of journal comparison, journal self-citation rate, impact factor, immediacy index, and journal h-index were analyzed under the conditions of containing as well as eliminating the self-cited data. On the other hand, the correlation between author self-citation and number of co-authors, age of reference article, location of reference in original articles, and author h-index were examined in the aspect of author difference.esults suggested that moderate significant correlation existed between the journal frequency self-citing and frequency self-cited rates. Those journals with higher self-citing rate tended to be more productive. The journal self-citation rate had no significant correlation with both impact factor and immediacy index. Under the conditions of containing or eliminating journal self-cited data, a high significant correlation between impact factor and 5-Year impact factor was identified but with a significant difference in the value. Analysis on longer period of h-indices showed similar pattern as on the analysis of impact factor. With shorter citation window of h-indices, self-citation rate and h- values were observed to be moderately correlated in some years.n the aspect of author difference, the self-cited rate of multi-authored articles was higher than single-authored ones. The correlation coefficient between the number of authors and author self-citation rate was law. Self-citing references were found to be more recent than those citations to others. Authors tended to cite their own previous published works in the introduction, result, and method sections. In the sections of method, result, and conclusion, self-citing references are more common than citing to others. No matter containing the self-cited data or not, insignificant effect was found on the author h-values and h-index. However, the correlation coefficients were strong between the author h-value and both their productivity and the number of total cited times.ased upon the results, suggestions were made as follows. When evaluating the environment technology related journal publication, using 2-Year impact factor and 2-Year h-index instead of longer period ones would be adequate in the citation window setting. Impact factor, immediacy index, and journal/author h-indices seemed all robust enough against self-citation. Thus, it is not necessary to eliminate the self-cited data when doing environmental technology related journal or author evaluation. The journal productivity should be taken into account when measuring journal self-citation rates. For surveying the self-citing rationality, each article’s introduction section could be a priority target.中文摘要 i文摘要 iii次 v次 viii次 xi壹章 緒論 1一節 問題陳述 1二節 研究目的 8三節 研究範圍與限制 9四節 名詞解釋 11貳章 文獻分析 15一節 引用文獻分析 15二節 自我引用 24三節 作者自我引用 33四節 期刊自我引用 50參章 研究設計與實施 63一節 研究設計 63二節 研究對象 68三節 研究步驟 73四節 資料處理 77肆章 期刊自我引用分析 79一節 自我引用率與被自我引用率 81二節 自我引用與期刊影響係數 97三節 自我引用與期刊立即指數 110四節 自我引用與期刊 h 指數 118五節 綜合討論 134伍章 作者自我引用分析 145一節 自我引用與合著者數 145二節 自我引用與參考文獻新穎程度 153三節 自我引用之位置 160四節 自我引用與作者 h 指數 169五節 綜合討論 178陸章 結論與建議 183一節 結論 183二節 建議 188三節 研究貢獻 190四節 進一步研究之建議 192考文獻 195錄錄一：期刊歷年研究論文數 211錄二：期刊歷年參考文獻數 212錄三：期刊歷年被引用篇數(當年) 213錄四：期刊歷年自我引用篇數/次數 214錄五：期刊歷年被自我引用篇數/次數(當年) 215錄六：各期刊歷年自我引用率 (%) 216錄七：各期刊歷年被自我引用率 (%) 217錄八：各期刊影響係數 218錄九：各期刊影響係數排名 219錄十：各期刊五年影響係數 220錄十一：各期刊五年影響係數排名 221錄十二：各期刊立即指數 222錄十三：各期刊立即指數排名 223錄十四：各期刊1年h指數 224錄十五：各期刊2年h指數 225錄十六：各期刊5年h指數 226錄十七：文章作者數、引用與被引用次數 227錄十八：作者自我引用/引用他人文獻位置 236錄十九：作者作品數、被引用次數及 h 指數 245application/pdf2169187 bytesapplication/pdfen-US作者自我引用期刊自我引用影響係數立即指數h 指數author self-citationjournal self-citationimpact factorimmediacy indexh-indexthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/179706/1/ntu-98-D91126003-1.pdf
