近年來平台商業模式席捲全球，Google、Amazon、Facebook、Airbnb、Line等平台領導者們，改變了人與人之間的互動、翻轉現代的生活，並從平台中取得價值、獲得優勢，進行一場以生態系為主的競爭遊戲。此股炫風吹向經濟體中的不同環節，讓企業與企業、產業與產業之間的互動關係發生變化，同時造成許多無法因應平台經營模式與競爭策略的企業快速衰退。因此，在此股潮流之中，舊有企業如何成功轉向平台經營為本研究之重點。 有別於分析成立之際即以平台模式為主的個案公司，本研究結合了價值鏈經營模式、以及平台經營模式的觀點與相關學術理論，採用縱斷面研究方法探討典範企業—台積電30年來經營模式的轉變歷程，分析其如何一步步重塑半導體產業結構、佈局平台策略並成功轉型，成為半導體產業的巨頭之一，並形成台積大同盟的生態系與兩大IDM對手展開全面競爭。 透過本研究之分析與歸納，發現「價值鏈」與「平台」兩者的商業模式要素內涵與經營思維迥異，前者專注本業、著重內部優化，以低成本或差異化為主要的競爭策略；後者則強調擴張營運範圍、槓桿外部資源，共同創造更多價值獲得雙贏局面。而價值鏈模式之企業可從建立內部平台開始、轉變到供應鏈平台，接著發展至雙邊平台的演化方式進行轉型，但不是所有企業都具備成為雙邊平台領導者的潛力，必須確認自身提供的價值是否為整個技術系統所需、以及能否同時為產業中許多企業解決商業問題。當企業成功轉為雙邊平台之際，即可專注於提高平台的網路效應與轉換成本等策略行動上，追求大者恆大及生態系競爭之目的。 / In recent years, the platform business model sweeps the world. Google, Amazon, Facebook, Airbnb, Line and other platform leaders not only changed the way people lived but also obtained values from the platform’s network. These values are key competitive advantages for platform leaders to win the game of business. However, the new type of business model is threatening pipeline business, and some pipelines even rapidly declined after attacking by platforms. Therefore, how pipelines can survive and turn successfully to platform-based business is the main discussion in this research. This study combined the academic theories of two business model: value chain and platform to explore the transformation of business and strategy of TSMC, which is one of the leading semiconductor companies in the world, in the past 30 years. The case study followed by analyzing how TSMC reshaped the semiconductor’s value chain and then adopt the platform strategy for enterprise transformation. Now, TSMC has its own ecosystem that can beat with other two giant IDM competitors. With the in-depth case study of the changing in TSMC’s business model, we had three conclusions. Firstly, we find out that the business model of “value chain” and “platform” has the different connotation and strategic thinking. The former enterprises focus on its own business, pay attention to internal optimization, and take advantage of differentiation or low cost for competition. However, the later ones emphasize the expansion of operating scope, leverage external resources, and co-create with partners for more values to pursuit the win-win situation. Secondly, enterprises with the value chain business model can develop the platform business model by establishing the internal platform at the initial and then expand to supply chain platform and two-sided market platform. But it's worth noting that not all enterprises have the potential to become a platform leader. It must satisfy two prerequisite conditions: (1) the own value is essential within an industry, and (2) can solve the business problems of different companies at the same time. Thirdly, when enterprises successfully become the platform-based business, enlarging network effect and switching cost are two primary actions to pursue and keep platform leading strategy.
