本研究提出一個測量期刊引用影響的整合式概念模型,並應用結構方程模式方法在圖書資訊學相關領域的50種期刊資訊進行以「期刊屬性」、「期刊易取性」及「期刊多樣性」等三項為「期刊引用」的前置因素理論模型的實證。整體模型的可解釋變異量為39.4%,其中測量模型的結果:以文獻篇數測量「期刊屬性」,以文件獲取性測量「期刊易取性」,及主題多樣化來測量「期刊多樣性」具顯著效果;而影響係數、立即指數及全部引用數來測量「期刊引用」,則均具顯著效果。結構模型的結果:「期刊引用」受到「期刊多樣性」的影響,但「期刊屬性」與「期刊易取性」則不具顯著性影響。The study proposes an integrated conceptual model to assess the journal citation impact. The antecedent factors include journal attributes, journal accessibility, and journal diversity. The structural equation modeling (SEM) with partial least square (PLS) is applied to conduct the empirical study within the fifty journals in the field of library and information science. The result shows that the antecedent factors account for 39.4% of the variance in journal citation. The result of measurement model shows that the number of articles is a good indicator for journal attributes; document availability is a good indicator for journal accessibility; and subject variety is a good indicator for journal diversity. As for the journal citation, three indicators include impact factor, immediacy index, and total citations are all good indicators. Moreover, the result of structural model shows that journal citation is significantly influenced by journal diversity, while there is no significant effect of journal attributes and journal accessibility.
