資料包絡分析法應用於圖書館電子資料庫使用績效之研究

Abstract

圖書館電子資源之購置成本逐年增加,如何評估電子資源之使用績效為一重要之課題。本研究應用資料包絡分析法(DataEnvelopmentAnalysis,DEA)進行電子資源的使用績效評估,包括電子資源之效率分析、差額分析與敏感度分析等,並以台灣某大學圖書館2010-2011年所購買的資料庫作實證分析。結果發現,資料包絡分析法可根據電子資料庫各項投入產出項的變數,進行各電子資料庫最大化效率值的計算,並提供效率值的比較、未達效率之電子資料庫改善方法等,較過去評量方法提供更多元且客觀的資訊給予決策者參考。

The cost of e-resource for library gradually increased every year. How to evaluate the using efficiency of e-resources had become one of the most important issues. This study applied Data Envelopment Analysis (DEA) method to evaluate the using efficiency of e-resources in the library. It included the efficient analysis, slack variable analysis, and sensitivity analysis of e-resource. This study took the database purchased by University A as the research target for empirical analysis. The results showed that DEA method could generalize the variables of each input and output based on the evaluated unit to calculate the maximum value of efficiency of each database then provide the comparisons and suggestions for improvement. The information provided by DEA was more diverse and objective than past evaluating methods.
