台灣地區行動網際網路服務之可用性評估

劉明宗, Ming-Tsung, Liu Unknown Date (has links)
針對行動網際網路服務,本研究先根據文獻建構出一評估可用性之初步架構,認為影響可用性的因素包含了「使用者個人特質」、「通訊基礎建設」、「服務廠商因素」及「行動裝置易用性認知」,接下來透過問卷調查以及統計分析的方式,進一步驗證此架構的正確性,建構出適於描述台灣地區行動網際網路服務可用性之評估架構。 本研究發現,使用者對於行動網際網路服務的觀感皆透過行動裝置而來,亦即「通訊基礎建設」與「服務廠商因素」之效果皆須透過中介變數「行動裝置易用性認知」才能發揮作用,而「行動裝置易用性認知」再影響到可用性,亦即「行動應用服務可用性認知」因素,而此結果代表使用者對於「通訊基礎建設」與「服務廠商因素」兩者的觀感必須透過行動裝置才感受得到,也就是說,如果沒有行動裝置存在,使用者對於後端之人文因素(服務廠商)與技術因素(通訊系統)一無所知,而這樣的結論反映在整個架構的意義,是「行動裝置易用性認知」對於可用性來說具有舉足輕重的地位;本研究進一步發現,可用性本身對於滿意度有著正面的直接效果,代表可用性愈高也會有較高的滿意度,而在同時,「使用者個人特質」代表著不同的使用者特性,如使用經驗、服務相關知識與人口統計變數,而就不同特性而言,對於「行動裝置易用性認知」與「行動應用服務可用性認知」亦有顯著差異。 就「通訊基礎建設」而言,良好的網路訊號與服務後端系統是提升可用性的主要效果來源之一,而「服務廠商因素」則需以產品策略與服務提供品質作為策略主軸;在「行動裝置易用性認知」中,軟硬體操作與使用者支援程度對「行動應用服務可用性認知」有著最大的效果來源,顯見行動裝置是否容易操作,使用者是否能得到適當支援乃為提升可用性的主要直接原因;最後,本研究發現使用者的知識多寡在「行動裝置易用性認知」與「行動應用服務可用性認知」上皆有顯著差異,並顯示知識愈豐富的使用者往往認為行動裝置愈好用、行動網際網路服務的可用性愈高;因此,維護良好網路品質、擬定正確產品策略、改善行動裝置軟硬體操作、適時提供使用者支援與教育使用者皆可大幅提升整體服務的可用性水準。 / This study aims at building a framework to evaluate the usability of Taiwan’s mobile Internet services. An initial conceptual model is first constructed by a thorough literature review. It includes four influencing constructs: User Characteristics, Backend Infrastructure, Service Provider Aspects, and Ease of Use of Mobile Appliances. With the concepts of each construct defined, a survey is then conducted to verify the relationships among the variables. The analysis results show that User Characteristics and Ease of Use are directly related to the perceived usability, whereas Backend Infrastructure and Service Provider Aspects are indirectly related to the perceived usability. This implies that users perceive the usability through the mobile appliances’ ease of use. It is also concluded that fast and stable network connection, effective products strategy, superior service level, user-friendly mobile appliances, sufficient customer support and education for users are the keys to a successful mobile Internet service.

未來寬頻行動服務的發展策略

韓文卿, Han, Wen-ching Unknown Date (has links)
本研究以第三代行動通訊(3G)技術標準之提出與應用,影響所及的相關產業活動的變化下,企業在經營策略發展上最佳的規劃方向為題。在無線通訊與網際網路持續交相演化發展,從前的窄頻已升級到寬頻,從前的有線已提升到無線、行動;顯然行動網際網路已取得未來發展的主流地位。由於寬頻行動網路的未來影響既深且廣,舉凡個人生活、企業經營、社會制度,及經濟活動都將出現解構與重組的變化模式,企業應如何掌握機先及變化的軌跡,調整企業的營運策略,將是企業成功的關鍵因素之一。 因此本研究從無線通產業發展的匯流趨勢出發;1)探討寬頻行動服務的技術與產業應用的發展架構;2)探討寬頻行動網路的生態演;3)整理有關的策略選項、解析產業結構的轉移,企業願景及核心競爭優勢的基礎。從而,運用解構與重組理論及動態的策略觀點,提出未來寬頻行動服務的策略發展規劃方向,以為企業策略管理研究之參考。 / Abstract This study is based on the application of the recent launched 3G technology standards to explore the impact on the related industrial activity and the strategy of optimizing the managerial benefits. Due to the recent fast development of the wireless communication and internet; the narrow band internet has been replaced by the wide band internet and the wire internet service has been replaced by the wireless and mobile internet service. The mobile internet will soon lead the industry in the near future. Since the broad band mobile internet is going to results in a huge impact on the personal lifestyle, industrial operation, social infrastructure, and even the economical activity. It becomes a key factor for an enterprise to face on the model and change of the upcoming disaggregation & aggregation and then adjust the current operational strategy to pursuit the sustain success in the future. Therefore, this thesis starts from the analysis of the future trend of mobile internet industrial development and then study on 1) the framework of broad band mobile service V.S. industrial application, 2) the Eco-revolution the broad band mobile internet, 3) the basis of strategic options, shifting of industrial infrastructure, industrial vision, and core competence advantage. Thus, this study utilizes the theory of the disaggregation & aggregation and the dynamic strategic point of view, to propose the strategic planning direction of future wide band mobile service, so as to be the research reference of business strategic management.
