在資訊科技與網際網路的快速發展下,政府為了提昇行政效率與國際競爭力,正積極建置電子化政府相關設施。我國於1998年開始建置公開金鑰基礎建設(Public Key Infrastructure,PKI),並於2002年推動「自然人憑證發證計畫」。政府所簽發的自然人憑證,即是透過政府機關PKI驗證機制,對網路使用者進行身份確認,並確保其資料傳輸時的安全。由於自然人憑證能有效地解決網路身份辨識不易與資料傳輸安全性不足等問題,因此被視為是電子化政府的基礎建設。但依據內政部憑證管理中心的統計資料顯示,自然人憑證的發卡量僅有一百多萬張,其與政策預期目標仍有一段差距。 為了有效瞭解自然人憑證的採用因素,本研究以Rogers的「創新擴散」(Diffusion of Innovations)為主要參考架構,並結合其他相關理論與資訊,例如:科技接受模型、信任模式,針對「自然人憑證」的採用者與潛在採用者進行探討。而本研究目的如下:一、瞭解「自然人憑證發證計畫」的推行現況;二、探討自然人憑證的「認知屬性」在採用者與潛在採用者之間的差異;三、探討採用者與潛在採用者對於「宣傳管道」與「信任」的看法;四、以採用者與潛在採用者的角度,尋找出影響自然人憑證政策擴散的因素。 本研究利用T檢定、單因子變異數分析與邏輯斯迴歸等量化分析方式,對自然人憑證採用因素進行研究,其研究發現如下:一、自然人憑證缺乏通盤及縝密的宣傳計畫;二、採用者與潛在採用者之間具有顯著差異的變項:相容性、相對優勢、認知易用性、人際溝通、大眾媒體、對政府信任與對網路信任;三、採用自然人憑證之正面顯著因素:相容性、相對優勢、認知易用性與大眾媒體。
As information technology and the Internet advance rapidly, in order to increase administrative performance and international competitiveness, our government actively establishes e-government implement. Our government started to build PKI in 1998 and promoted 「The Project of Citizen Digital Certificate」 in 2002. Citizen Digital Certificate which is assigned by the government is through the verification of the PKI mechanism to confirm the identity of Internet Users, and ensure the security of data. Citizen Digital Certificate successfully resolve the identification problem of Internet users and data transmission security. Therefore, it is regarded as the most important foundation of e-government implement. However, according to the statistics of the MOICA, the number of Citizen Digital Certificate still does not achieve the expected policy goal. In order to understand the application factors of Citizen Digital Certificate, this research is based on of Innovations Diffusion theory of Rogers and combines with other theories and frameworks such as Technology acceptance model and Trust model so as to examine the users and sub-users of Citizen Digital Certificate. The purposes of this research are as follows. First, to understand the popularization of Citizen Digital Certificate; second, to investigate the differences between users and sub-users in perceived attributes of Citizen Digital Certificate; third, to examine the perspective of users and sub-users toward publicity and trust; and last, to find the affect factors of diffusion of Citizen Digital Certificate policy. All the data of valid samples were analyzed by using T-test, one way ANOVA, and Logistic Regression Analysis. The findings of this research go as follows: (a) Citizen Digital Certificate lacks overall and deliberate promotion plans. (b) users and sub-users have critical different variables: compatibility, relative advantage, perceived ease of use, communication, mass media, credibility of our government, and confidence of the internet. (c) positive prominent factors of using Citizen Digital Certificate include compatibility, relative advantage, perceived ease of use, communication, and mass media.
