隨著資訊科技與通信技術的快速發展，電子商務不但為企業帶來了創造財富的機會，更轉變了企業建立競爭力的模式。為因應國際環境改變所帶來的變革，政府相關部門正投入大量之人力與資源推動產業電子化，以期能夠提昇各產業在國際上之競爭力。為確實掌握國內產業電子化的現況與資源投入效益，應建立績效指標之衡量機制，評估目前電子化計畫的績效表現。

　　本研究之目的在建立一可與國際相比較之產業電子化績效衡量指標，以掌握國家產業電子化現況、國際之趨勢，協助政府了解產業電子化推動計畫之成效；並提出電子化績效指標架構，探討指標之間的關連及應用，以作為政府及企業推動電子化計畫績效評估之基礎。

　　本研究以國際性電子化指標為基礎，利用文獻探討及實務上電子化專案績效指標之蒐集整理歸納，提出階層式電子化績效指標架構，分別以經濟發展面及資訊科技發展面將架構分為國家、產業以及企業競爭力三個層次，並深入瞭解電子化之投入對於各個層次之影響。在企業關鍵能力與產業驅動力方面，由資料驗證參與D計畫企業之關鍵能力與產業競爭力有顯著的影響關係。進而以因果關係模型驗證近14年產業e化環境及國家總體經濟指標之關係，發現製造業之資訊科技採用佔總資本支出之平均水準為2.58%，對總體經濟指標績效則呈現三年的落後績效，而批發零售餐飲業資訊科技採用佔總資本支出之平均水準為9.97%，對總體經濟指標績效卻無顯著的影響，運輸倉儲通信業之資訊科技採用佔總資本支出之平均水準為4.95%，對總體經濟指標績效表現四年的落後績效。以國家層次而言，國家e化應用程度對於國家總體經濟指標績效並無顯著的影響。另一方面，產業層次（製造業與批發零售餐飲業）及國家層次資訊科技的投入皆會受到國家前幾年總體績效指標績效的影響，因此國家總體經濟績效之表現會促使國家及產業資訊科技投入產生效益。

　Internet technologies have been widely embraced by enterprises worldwide to conduct their business to dramatically improve their performance. Realizing the importance of e-business, government in Taiwan has proposed and supported many national policy initiatives in regarding to e-business projects and to improve the information and communication technology (ICT) infrastructure, expecting the industries can increase their international competitiveness thereafter. To justify the ranking of e-readiness in Taiwan and the realized benefits through the initiatives, it is necessary to formulate a framework with metrics on respective performance indicators in order to measure the e-business performance in a comparative level.

　One of the main objectives of this thesis is to formulate a framework in order to measure the e-business performance in a international comparative level. This research proposes the e-business performance metrics and justifies their relationship and interaction. The proposed framework can also serve as a reference for the government to evaluate e-business policies.
This research adopts the international practices as the foundation to develop the hierarchical framework of e-business performance indicators. The framework has two dimensions, economic and Information Technology (IT) development, and is separated into country level, industry level and firm level. Concerning the relationship of firm level and industry level, the key competences of enterprises which joined the D-plan demonstrated significant influence on industrial competitive indicators. Furthermore, the causal relationship models are utilized to verify the relationship between the industrial e-business environment and the macro economic indicators in the past 14 years, where the results suggest that the manufacturing industry averagely spent 2.58% of total capital investment on IT investments and has lagged for three years in the performance of the macroeconomic indicators. Similarly results for the wholesale, retail and food industry, which reaches 9.97% yet has no significant influence on the performance of the macro economic indicators, and for transportation, storage and communication industry it has invested nearly 4.95% and four years lagged. For country level, e-business applications have no significant impact on macroeconomic indicators. On the other hand, IT investment of the industry level (such as manufacturing, wholesale, retail, and food industry) and the country level are shown to be influenced by the performance of the macroeconomic indicators for the past few years. Accordingly, the performance of the macroeconomic indicators will produce benefits for the IT investments in the country and industries level.
