近年來，資訊社會的典型現象紛紛浮現，資訊量爆炸對於人類在經濟、政治與文化等生活各層面上的重大影響性，皆促使人類對於網路頻寬和傳輸速度的渴求程度越來越強烈。於是，窄頻網路已無法再滿足龐大且多元的資訊傳輸，取而代之的是寬頻網路的應用。在許多國家陸續推動寬頻網路建置與接取政策的同時，也重新關注普及服務的定位以及其所能發揮的功能，開始思考是否可運用普及服務機制以達到寬頻網路普及接取的目標。OECD早在2003年就曾探討將寬頻網路接取制定為普及服務義務的先決條件。歐盟自2005年起也開始正式討論是否要修改普及服務指令以將寬頻網路的接取納入普及服務的義務當中。瑞士、芬蘭、英國和美國則已經陸續開始推行寬頻普及服務的相關政策。而我國國家通訊傳播委員會則於2007年開始相繼推動「村村有寬頻」與「部落(鄰)有寬頻」政策，要求普及服務提供者提供偏遠地區居民2 Mbps的寬頻網路接取服務。 然而，將寬頻接取定義為普及服務目前卻受到廣泛探討與爭論，最關鍵的問題就是寬頻網路究竟是不是資訊社會中的基本電信服務。因此，本研究旨在探討普及服務機制在各國推動寬頻網路建置與接取政策上的定位，以及目前寬頻普及服務的相關推動方式。這其中牽涉的範圍廣泛，包含寬頻普及服務接取速率的認定、政策推動單位、業者的範圍界定、經費來源的規劃與調整等，在在都牽動著國家寬頻網路的發展。 本研究歸納我國目前數據普及服務與寬頻政策之間的關係，並依據國外推動寬頻普及接取政策的綜合經驗，對於我國未來推動寬頻普及服務的政策提出以下研究建議：（一）確立我國寬頻普及服務的政策目標，政府應該將寬頻普及接取的目標納入「數位匯流發展方案」，確立在2012年之前可以讓我國所有家庭都能接取基本的寬頻網路服務；（二）整合各部會資源，由NICI負責統籌與協調各部會的力量與資源，最重要的是要求各部會配合以達到資源整合的效果；（三）政府與業者合力推動寬頻普及服務，數據普及服務提供者負責建置寬頻網路，政府則負責電腦設備或是網路教育訓練等的後續補助；（四）整合有線與無線技術達成目標；（五）考量是否挹注公共經費以促進寬頻建置的目標。 / With the advent of information society, people become eager for the greatest degree of bandwidth and highest transmission rate on the Internet. Obviously since narrow bandwidth can neither meet the service demands of the masses, nor transmit all data efficiently, broadband has taken on ever greater importance. When implementing policies in regard to broadband infrastructure and access, many countries start to pay their attention again to the role and function of universal service and the feasibility of promoting universal broadband access by universal service mechanism. Starting in 2003, OECD has debated the preconditions for widening the scope of universal service obligation to include broadband. The EU also began in 2005 the formal public consultation to discuss the possibility of revising Universal Service Directive to include broadband as part of universal service obligation. However, redefinition of the scope of universal service to include broadband now faces many challenges. Among them, whether broadband is an essential telecommunications service necessary for information society has become the most crucial issue. Therefore, this study aims to explore the role of universal service in policies of promoting broadband infrastructure and access, as well as current approaches to accelerate implementation of universal broadband access in different countries. Relevant issues include determination of data transmission rate, involvement of government and service providers, sources of funding, among other issues yet to be resolved. By comparison of the approaches among foreign governments with that of Taiwan, this study suggests the following: (1) The Government should include the goal of universal broadband access into its “Digital Convergence Development Plan,” providing every household in Taiwan access to basic broadband service by 2012. (2) NICI should take charge of coordinating resources among Governmental Departments so as to make effective use of all resources. (3) The Government and telecommunications operators should cooperate closely and strive to deliver broadband universal service. (4) Both wireline and wireless technologies should be fully utilized. (5) The role of public funding for this goal should be highly considered.
