Summary: | 「行動革命」到來,智慧型手機、平板或各式行動載具滲透人們日常生活,對人類的傳播模式產生了極大的變化。同樣的,這場行動革命,也襲捲到了公部門,「行動化」趨勢改變了政府現有的傳播方式。
在臺灣近年的行動媒介環境中,Line成為最普及的大眾化通訊程式,臺灣公部門也藉Line此行動平臺,試圖突破過往的傳播方式,公部門在Line平臺中的公共服務類官方帳號也先後上線。隨著行動裝置成為不可或缺的工具,這樣的行動官方帳號,更已成為臺灣政府在行動媒體時代資訊發布的重要管道。
基於上述研究背景與動機,本研究擬達成之研究目的為:(1)瞭解臺灣Line公共服務類官方帳號使用者的輪廓形貌;(2)調查臺灣群眾對於Line公共服務類官方帳號的使用行為;(3)瞭解影響臺灣群眾採用Line公共服務類官方帳號的因素;(4)建立並驗證描述「知覺實用性」、「知覺易用性」、「資訊內容品質」與「使用滿意度」之因果關係的假設和觀念性架構。
最終,以436份網路問卷資料,經結構方程模型驗證,本研究的5項假設均成立:Line公共服務類官方帳號中,使用者的「知覺實用性」、「知覺易用性」和「資訊內容品質」,皆對Line公共服務類官方帳號使用者的「使用滿意度」有正向且顯著的相關性。此外,研究中也檢驗出Line公共服務類官方帳號的「知覺易用性」以及「資訊內容品質」皆對於其「知覺實用性」有正向且顯著的關係。其中「知覺實用性」,是影響使用者採用Line公共服務類官方帳號的最重要因素。
本研究構建並驗證影響臺灣群眾對Line公共服務類官方帳號採用之因果模型,當中各構面之間皆具顯著相關,因此,以TAM為基礎,並加入「資訊內容品質」 的擴增模型,在預測臺灣群眾對Line公共服務類官方帳號的採用上,具有顯著效果。 === The development of mobile access technologies and the rapid growth of mobile broadband along with explosion of the mobile application ecosystem have created a new communication channel between the public administration and citizens. With mobile devices being one of the main tools of communication, Taiwan government agencies are increasingly using Line, one of the most popular messaging Apps in Taiwan, in a bid to increase effective communication with their citizens. Therefore, the purpose of the paper is to (1)understand the behavioral and demographic attributes of the Public Service Line Official Account users; (2)propose an integrated model of Public Service Line Official Account acceptance by integrating perceived usefulness, perceived ease of use from Technology Acceptance Model(TAM), information quality theory and user satisfaction theory.
The model and relationships were tested and validated with the Structural Equation Modeling(SEM), using data gathered from 436 users of Public Service Line Official Account in Taiwan. The results suggest that user satisfaction is directly influenced by perceived usefulness, perceived ease of use and information quality, whilst perceived usefulness is directly influenced by perceived ease of use and information quality. In addition, perceived usefulness to be a major influence on the adoption of Public Service Line Official Account in Taiwan.The implications of these findings are discussed.
