數位落差是資訊科技與數位化經濟快速發展下的產物。研究發現數位落差代表著機會的消失，更反映著社會基本素養、貧窮、醫療或其他社會問題存在的議題，只要數位落差存在，經濟的發展、國家競爭力的提升、人民生活的進步都將受到拖延而遲緩。事實上，有關數位落差如何發生、如何衡量、影響層面與嚴重性以及如何縮減數位落差的相關議題不斷的被討論，各國政府與國際組織或者自行組成研究小組，或者邀請學者專家針對縮減數位落差議題加以探討，期以建立一個公平共享數位化所帶來各項利益的社會。然而研究顯示縮減數位落差各方努力的成效仍不如預期。如何縮減數位落差的相關研究至今仍有許多缺口待彌補，包括數位落差現象觀察不完整、欠缺一個具有全方位評量的架構、縮減數位落差的方案與數位落差現象間的因果關係並無法提出一個對應的脈絡、如何檢討縮減數位落差策略的執行績效等等。 本研究由文獻探討、資料分析提出數位落差整體衡量架構，繼之由策略管理的角度建立以平衡記分卡為基礎之數位落差策略績效評比架構，確立縮減數位落差之願景、使命、策略、策略目標以及建立以BSC為基礎之數位落差評量指標。研究並提出縮減數位落差策略缺口之定義與檢視方法。數位差衡量指標以層級分析法求得權數，並將指標與策略結合，衡量縮減數位落差策略在數位落差整體表現的實質績效。研究獲得以下結論： 1. 研究提出一個國內與國際數位落差觀察與衡量整合架構，架構共分為ICT普及、均等機會、資訊社會與國家競爭力四個構面。 2. 研究結果認為縮減數位落差在策略上應考量受益群體、政府功能與流程、全國性學習與成長以及公共財政的支援。 3. 利用策略地圖所闡述的因果特性進行策略缺口分析。研究結果提出四類水平策略議題缺口、五類水平策略目標缺口、兩類垂直策略議題缺口與三類垂直策略目標缺口。水平策略缺口分析可確保策略議題之完整性，而垂直缺口分析則可檢視策略間之因果關係是否連結。最終目標則是保證縮減數位落差策略之品質。 4. 本研究將策略與數位落差評估架構結合，除了以AHP計算各指標權數，瞭解各指標之重要性，並於指標架構表中指出該指標為績效驅動指標，或為策略執行結果指標。 5. 實例分析發現，目前台灣在縮減數位落差議題上水平策略缺口包含遺漏策略議題、缺少因應台灣特質之策略與策略目標、策略議題不明、遺漏重要策略目標、缺少適當衡量指標以及無效的策略等等。垂直策略缺口情況較嚴重，表示策略間的邏輯性並未詳細檢討過。 研究最後對我國政府提出以下建議：1.重新檢討目前衡量數位落差之架構、2.擬定縮減數位落差的策略規劃與管理機制、3.借鏡先進國家的成功案例並進行跨國的合作、4.尋求質的改善。此外提出五項衍生之議題，值得後續繼續觀察與探討：1.考慮如何將本研究所提出之架構更精鍊。2.目前全球的趨勢已由觀察數位落差的移轉至數位機會的存在，在這樣的新思維下，策略上應有哪些重大的改變？如何將這種轉變以無縫的方式連接，是值得持續觀察的議題。3.指標術語或專用名詞更精確的解釋與規範。4.跨國應用與比較，實地訪談，徵詢更實際的意見與建議，增加本研究所提出架構之實務價值。5.設計問項、核定與統一衡量單位、定義問項目的與建立題庫。 / Digital divide (DD) is the byproduct of the fast development of information technologies and digital economy. Previous researches indicated that the existence of digital divide implies the vanishment of digital opportunities, and furthermore, it reflects the presence of servere social problems including literacy, poverty, medical systems, etc. As long as there is a gap, the development of economy, national competitiveness, and the advance of human lives will be affected. As the matter of fact, the issues of the causes, the measurements, the impacts as well as the reducing of digital divide have been constantly discussed over a decade. Governments and international organizations have put a lot of efforts in pursuit of establishing a society in which people would equally share the benefits of e-society by minimizing the gaps. Unfortunately, research findings have indicated that the efforts for reducing digital divides were inconvincible. Major themes, such as the observation as well as the evaluation of the status of digital divide in an integrated view, the establishment of cause-and-effect relationship between strategies and the outcomes, are still absent in the discussions or researches. By reviewing literatures and analyzing the documents collected, this research first provides an integrated framework for simultaneously analyzing domestic and international digital divides. The framework is later incorporated with the BSC to form the strategic management platform for reducing DD. To ease the process for a nation to build its own DD-BSC and to refine its DD strategies, this research also presents a systemized approach to locate strategic gaps. The AHP is adopted in this research to verify the consistency of the structure of the framework as well as to calculate the weights of the indicators. In summary, this research contributes the following results: 1. An integrated model, containing ICT Diffusion, Equal Opportunity, Information Society and National Competitiveness dimension for the measurement and evaluation of digital divide, is presented in this research. 2. Research findings suggest the strategies of reducing DD should be planned based on Beneficiaries, Governmental Functions and Processes, Nation-Wide Learning and Growth and Public Finance perspectives. 3. The research proposes and defines four types of horizontal strategic theme gaps, five types of horizontal strategic objective gaps, two types of vertical strategic theme gaps and three types of vertical strategic objective gap types. The ultimate goal of strategic gaps analysis is to ensure the qualities of the strategies of reducing DD. 4. The measurements proposed in this research can be used to measure the status of DD and to evaluate the performances of the strategies of reducing DD. 5. The case study of Taiwn reveals that in the issue of reducing DD, the government could initiate more effective strategies by referencing other developed countries. Major problems of Taiwan regarding to reducing DD include the lack of strategic objectives, the lack of proper measurement, the broken links among strategies as well as between strategy and its objectives. Suggestions proposed to the government including the reexamination the scopes and strutrucures of measuring the status of digital divide, designing a strategic planning and control system for reducing DD, seeking for cross-nation cooperations and focusing on improving the qualities of the DD strategies. Future studies may focus on the refinement of the frameworks proposed in this research; determine the changes that are affected by the new concept of digital opportunities; define more clearly and precisely the terms used in observing or measuring DD; design questionnaires and collect data regularly. Finally, more interviews and case studies are to be conducted to improve the practical values of this research.
