2008 年擁有158 年歷史的美國投資銀行，雷曼兄弟控股公司( Lehman Brothers Holdings Inc. )的破產，掀起全球性的金融風暴，進而促使全球經濟同時性大衰退。 曾經是美國、甚至全球最大的企業的通用汽車也蒙受嚴重波及，而宣告破產重整。 百年歷史的GM 公司的倒閉，使得『企業規模越大，越不會倒閉』的傳統觀念破滅 了！根據統計，一般企業的壽命，約在30 年，而世界上仍有許多維繫超過百年甚至 更久遠的企業。促使那些擁有百年歷史的企業，永續經營特質是什麼? 回顧1990 年，普拉哈(C.K. Prahalad) 和蓋瑞‧哈默爾 (Gary Hamel) 於「哈佛商 業評論」上發表了企業核心競爭力（Core Competence）模型的論文以及唐納．薩 爾 (Donald N. Sull) (2003) 在「成功不墜」所闡述企業永續經營模型。還有，日本 京都大學經濟學研究所的末松千尋教授於2002 年提出京都企業經營模式研究論 述。三者構成本論文研究的理論模型基礎架構。藉由NEC 的個案，以質化個案研究 的方式，對照這個模型架構，探討NEC 公司永續經營的特質，印證本理論架構基礎 的實用性與完整性。研究成果將可提供國內企業，邁向國際化、全球化、永續經營 上策略思考之參考。 本研究從NEC 個案中獲得企業永續經營準則、永續成功經營模式為： 一、 擬訂企業策略發展意圖，建構企業願景。 二、 藉由不斷創新，建構企業核心競爭能力。 三、 認識企業存在的意義，重視顧客滿意。 四、 建立開放平台，與供應商的水平分工。 五、 隨著經營環境變遷，勇於適時變革。 關鍵字：永續經營特質，企業核心競爭力，企業經營模式，成功經營模式 / A 158- year-old firm, the 4th largest investment bank in the USA, Lehman Brothers Holdings Inc. announced its bankruptcy in 2008.Rapidly stirred up a global financial credit crisis and became to a worldwide economic recession concurrently. The ever being biggest company in the USA and even in the world, General Motors Corporation was engulfed seriously and finally also sank into bankruptcy protection by the economic recession. Even having hundred years history company like GM Corp. was forced to reorganize by bankruptcy protection. The traditional concept, 「The larger of the scale of a company the less possibilty of the company will collapse」,was ruined！According to some statistics a company can last for about 30 years for average. But there are still many firms lasting for more than hundred years in the world. What is sustainable managerial essence of those firms? Let us review their theses of core compentence of the corporation in the article of Harvard Business Review in 1990 by Mr. C.K. Prahalad and Mr. Gary Hamel. and the theses of company`s sustainable managerial model in the book of「Revival of the Fittest」in 2003 by Mr. Donald N. Sull. Also let us review the theses of 「Kyo-siki strategic business model」in 2002 by Mr. Chihiro Suematsu, Professor of Kyoto University Graduate School of Economics. These three above expounding form the basic model of theory of this research. By the case study of NEC Corporation, taking antithesis of these expounding, a case study of qualitative research oriented, tries to find sustainable managerial essence of NEC and to prove the practicality and the completeness of the basic model of theory of this research. The research thesis is trying to offer some strategic references to the company in Taiwan during creating its sustainable managerial essence for company on the way of internationalization and globalization of company. From this research of NEC case study it has found some conclusions about company`s sustainable managerial priceples or company`s sustainable successful business model as the followings： 1. Implementing strategic intents and setting up visions for the company. 2. Building core competencies for the company by constant innovations. 3. Realizing the meanings of company`s existence and taking customer satisfaction as the first priority. 4. Constructting an open platforms for business collateral integration with vendors and partners. 5. Being brave in timly transfoming for the company fitting changes of the business environment. Key Words：sustainable managerial essence，core competence，managerial model，sustainable successful business model

本研究依據實際的經驗，與學術研究的探討分析整理，建構出一個符合實際 B2C 電子商務企業經營的「反饋循環電子商務模型」。此模型用以提供給電子商 務企業進行策略規劃，計劃執行時的決策依據，由於透過了整合企業核心競爭力 與成功的電子商務企業的關鍵成功因素，因此具備有良好的實際可行性。 模型的關鍵成功因素，係以整理學術界，業界實際經驗所得到的「完整版電 子商務成功因素表」做為基礎。「反饋循環電子商務模型」提供兩種提案評估方 式，第一種是透過「完整版電子商務成功因素表」的權重與分數協助企業進行提 案的評比選擇，第二種則是從核心競爭力與「完整版電子商務成功因素表」關鍵 成功因素契合度而得到的評比選擇。企業選擇的提案，如果能同時符合此兩種選 擇，則可以產生較強的正面績效。 第一種方式的權重配比，則可以透過對企業高層以德菲法方式獲得。最高分 數的提案被執行之後，也可以透過企業本身對於執行結果的檢討，調整權重配 比，進而反饋修正決策與計劃。因此本模型的另外一個特點是具有反饋循環的特 性，因應企業本身的狀況而調整，如此可以讓模型具有更大的彈性以因應經營環 境的快速變化。 然而，B2C 電子商務企業的成長是必須要在不同時間點投入不同的決策才能 獲得突破性的發展，第二種方式使用德菲法將企業核心競爭力與本表的關鍵成功 因素進行契合度的分配之後，也可以獲得單純從企業核心競爭力出發的決策結 果。此決策結果可以與透過權重評分的方式相印證，以確認透過模型所選擇的提案，與企業競爭力是契合的。 本研究透過實際的案例，將 Amazon 與PChome online 分別以歷史轉折點與 專案決策兩個角度來分析，透過大量的實際狀況來證明利用模型也可以得到與這 兩個成功企業的決策者的決策相同或接近的結果。同時在Amazon 分析中，也可 以看出決策者過度違反模型所羅列的電子商務關鍵成功因素時，企業將會暴露於 重大的經營風險之中。 / The goal of this research is to build a practically useful B2C e-commerce business model for decision making and project evaluation. The business model we proposed is “Cyclic B2C business model with feedback”, this new business model comes with lots of empirical and practical advantages to firms running B2C e-commerce. In this paper, the researcher integrates core competence and key success factors into decision making loop, and use a simple weighting method to calculate each proposal’s score for decision making. The author use Delphi method to enumerate B2C firm’s core competence as one input of the model. The other input of the model is a complete KSF (Key Success Factors) table which is sifted from previous researches and empirical KSF from success B2C firms. In the model, two simple methods are introduced to evaluate proposals developed by firm’s decision makers. After the evaluation process, we get score of each proposal, then we can choose the proposal with highest score as our final decision. Those two methods which are used to evaluate proposals are “sum of weighting” and “core competence & KSF matching”. Decision makers can examine top score proposals come from different evaluation methods and find out which can meet the criteria: “getting high scores in both method”, that is the answer. For KSF matching, a “Complete Success Factors Table” was developed by way of integrating research survey and empirical KSF from success e-commerce business. Combining this table with the proposed model, two cases, Amazon and PChome online are chosen to prove the accuracy of “Cyclic B2C business model with feedback”. After examined historical events and key strategy developed, we claim that the business model we developed in this paper is a practical and useful model for B2C firms.
