摘要 本研究之目的在透過實政研究方法回答兩個關於破壞式創新研究問題，首先，產業延續性創新速度與企業破壞式創新程度之關係為何？其次企業的破壞式創新程度對其績效影響為何？本研究透過文獻探討，設計問卷並以台灣資訊電子產業公開發行之企業進行問卷調查蒐集初級資料。經由統計分析，本研究得出兩重大發現，首先，產業延續性創新速度與企業破壞式創新程度為負相關，而企業對新產品開發專案之決策資訊充足要求程度會弱化此關係。其次，企業規模與財務績效有正相關，而企業破壞式創新程度會強化此關係。 / The aim of this research is to answer two research questions about disruptive innovation with empirical methodology. First, what is the relation between industrial sustaining innovation rate and a company's disruptiveness. Second, does a company’s disruptiveness impact firm financial performance? By collecting primary data, this research developed the questionnaire based on literature review and collected data from the publicly-listed companies in the Taiwan IT industry. With statistic analysis, this research has two significant findings. First, industrial sustaining innovation rate has a negative impact on an incumbent company’s disruptiveness and the accuracy of company investment decision on NPD project will weaken this relation. Second, firm size has a positive impact on firm financial performance and a company's disruptiveness will strengthen this relationship.
