    Abstract: 隨著軟體發展與演進，「軟體危機」因應而生，而軟體再用是解決「軟體危機」重要因應之道，因此探討軟體再用效益的演變將有助於產官學研在推動軟體再用相關政策之研擬參考。以往的軟體再用效益的研究大多強調局部性財務效益，而且是橫斷面研究。本文則較廣泛的就系統、程式、應用、管理、組織與產業等七大構面 42 個關鍵效益進行縱貫性研究。經由比較 1997 年上半年和 2000 年下半年兩個時期，國內主要軟體業者和專家學者的訪談和階層程序分析法問卷，歸納並探討軟體再用關鍵效益在國內的變化趨勢。本研究結果顯示(1) 軟體再用效益七個構面中，在重要性變化以系統屬性增加最多(0.068)，其次為產業屬性(0.021)；專案屬性的重要性減少最多(-0.054)。(2) 42 個關鍵效益中，減少系統出錯及跨平台的成本，增加元件品質等關鍵效益更受到重視。另一方面，專案中發展人數減少、開發類似軟體時間減少等效益的重要性則逐漸減少。亦即軟體再用的效益中，系統的穩定性、元件質的提昇和量的增加等關鍵效益更加重要，而且逐漸從重視個別專案效益，到組織外的跨專案效益乃至於整個產業的效益，以跨組織合作和軟體產業整體資源來面對日漸擴大和複雜軟體市場需求。 Software reuse plays a vital role when software crises occur along with the evolution of software development. It is expected that policy makers of software reuse in software industry will be benefited by this study. As most researches in terms of software reuse effects focus on project and cross section effects, the objective of this paper, however, involves a longitudinal study of the evolution of software reuse effects. It compares the outcome of analytic hierarchy process drawn from the questionnaire done with experts in 1997 and 2000. In addition, an evaluative model of software reuse effects with 7 dimensions and 42 criteria is included in this study. The findings indicate that (1) the system (0.068) and industry (0.021) dimensions are the leading main proportions; meanwhile, the project (-0.054) dimension is one of the main proportions that are decreasing in the evolution process among 7 dimensions. (2) Low frequency of system errors, low porting costs and high components quality are more emphasized. The size of team members working on the projects and the time spent on the project are losing their importance in the evolution among 42 criteria. In other words, more stable systems, high quality and quantity components have got more emphases than ever. Furthermore, the effects of industry levels are evaluated prior to those of project levels. The corporations among the software industry are about to ally to meet the more complicated and extensive market needs.
