本研究探討台灣民眾對於「行動支付」的接受度及使用意願,採用Venkatesh (2003)的整合性科技接受模式(unified theory of acceptance and usage of technology, UTAUT),並結合任務技術配適模型(task technology fit, TTF),一個人不只將其感知作為對技術的選擇,他們對新興技術的接受程度可以由好的任務技術配適度決定,此外,將性別及年齡視為調節變數,希望能從研究的結果得到更多的實證意涵。研究結果顯示:就直接效果而言,社會影響、個人創新性、認知風險、信任、技術任務配適均會影響使用意願,而兩項傳統因子「績效預期」、「投入預期」並不會顯著影響行動支付的意願。就間接效果而言,「信任→認知風險→使用意願」、「技術特性→技術任務配適→使用意願」、「任務特性→技術任務配適→使用意願」、「績效預期→技術任務配適→使用意願」及「投入預期→技術任務配適→使用意願」共五條中介效果的路徑獲得支持。納入調節變數的討論,男性樣本屬於務實主義,會考慮到任務與技術的配適狀況,女性則受信任感、風險影響;至於年齡的調節效果,年輕族群認知風險、社會影響適意願的主要解釋變數,非年輕族群則在乎績效預期與投入預期。研究結果可供發展行動商務時市場行銷策略的參考。
The study strives to examine the role of technological and behavioral variables in predicting behavioral intention of individuals to adopt mobile banking by integrating three pre-established frameworks of UTAUT and TTF. CFA and SEM analyses have been used to analyze the data collected from Taiwan mobile phone users. The statistical results support the significant association of social influence, personal innovativeness, trust, perceived risk, task technology fit (TTF) with intention to adopt mobile payments. The empirical findings also established the significant contribution of task (TAC) and technology characteristics (TEC) in facilitating TTF. Social influence and facilitating conditions don’t directly impact behavioral intension, but can influence TTF then indirectly affect the acceptance of mobile payment. We then consider the moderating effect of gender and age. These findings have important theoretical and practical implications, particularly for the development and marketing of mobile payment, which will support the long-term success of mobile commerce.
