本研究在以分析層級程序法(Analytic Network Process; ANP)觀點，探究專家與消費者對於綠色產品的關鍵因素，並以發光二極體(LED)燈泡為對象。透過整合性科技接受模式(UTAUT)的構面與因素定義，建構具備利益及成本考量之分析網路程序法 (BC-ANP)的架構與其因素，包括四個有關產品的構面以及其十四項因素。經過專家討論及內容效度分析刪除不合適之因素，再透過專家深度訪談決定構面間與因素間的相依及回饋關係。接著發放專家成對比較問卷以及分析網路程序法的運算，以獲得各因素與方案的優先順序。並對模型進行敏感度分析，以確保分析的穩健。 研究結論顯示，績效期望及效能期望影響結果較大，而社會影響與促進因素的外在影響層面相較之下略小。(i)人們對於產品能給予的益處或增加績效程度的特性感到最為重要，其次則為是否提供良好的效能；(ii)專家認為LED所帶來的主要利益為低耗能特質，而消費者則為LED在低污染方面的特性；(iii)專家及消費者均有強烈購買意願。另以「節省電費」準則對購買意願進行敏感度分析，結果顯示其的變動範圍穩定而不敏感。 This study tries to Investigate the critical factors in the adoption of LED (Light Emitting Diode) Illumination Lights based on Technology Acceptance Model from the aspect of BC-ANP. First we clarify influential factors through Unified Theory of Acceptance and Use of Technology (UTAUT), and then fit them to the structure a BC-ANP analytical framework, including four product-related dimensions and 14 factors. Second, we adopt experts’ opinions and content validity ratio to delete inappropriate factors, and determine the interdependent and feedback relationships for the dimensions and their factors. After that, we calculate the priorities of factors including alternatives according to the results derived from pair-comparisons, and execute sensitive analysis to ensure the stability of the proposed model. We observed that values of performance expectation and efficiency expectation are higher than the values of social influence and promoting factor. The major results are: (i) Consumers think that given benefits or performances of products are the most important, and the next is the produce efficiency; (ii) Experts view the main advantage of LED lights is its low energy-consumption, and consumers consider the low pollution of LED lights; and (iii) Experts and consumers have high intention of purchasing LED lights. Besides, the results of the sensitivity analysis on the factors of "electric bill" are rather stable.
