隨著人工智慧（Artificial Intelligence, AI）與高效能運算（High Performance Computing, HPC）市場快速成長，記憶體模組產業正面臨需求擴張與供應鏈結構變動的雙重挑戰。在台灣市場中，本土模組廠憑藉成本優勢與產業群聚效應形成高度競爭環境，使外資模組廠必須透過差異化策略建立競爭優勢。因此，美系記憶體模組廠如何透過價值鏈活動整合與策略性資源配置提升競爭能力，成為值得探討的重要議題。
　　本研究採用個案研究法，透過次級資料分析與半結構式訪談蒐集研究資料，並結合Porter（1985）之價值鏈理論與邱志聖（2020）提出之4C策略行銷分析架構，探討企業內部價值活動如何轉化為顧客成本結構之競爭優勢。研究結果發現，個案企業透過生產與研發能力提升產品可靠度並確保長期穩定供應，得以降低顧客之外顯單位效益成本（C1）；透過早期Design-in導入與技術支援服務，降低顧客之資訊搜尋成本（C2）；透過穩定的顆粒採購策略與供應鏈管理，降低顧客之道德危機成本（C3）；同時藉由韌體客製化與固定料號（Fixed BOM）設計，提高顧客轉換供應商之專屬陷入成本（C4）。上述價值鏈活動之整合，使企業得以在不依賴價格競爭的情況下建立結構性競爭優勢。
　　本研究整合價值鏈理論與4C架構，建立企業內部能力與顧客成本結構之分析框架，說明企業如何透過價值活動整合形成市場競爭優勢。研究結果除驗證4C架構於記憶體模組產業之應用價值外，亦為外資企業在競爭激烈之在地市場中制定策略提供管理意涵與實務參考。

With the rapid growth of Artificial Intelligence (AI) and High-Performance Computing (HPC), the memory module industry is facing significant market expansion and supply chain volatility. In Taiwan, local module manufacturers benefit from strong cost advantages and industrial clustering, creating intense competition. Consequently, how U.S.-based memory module companies establish differentiated advantages through value chain optimization and strategic resource allocation has become an important research issue.
This study adopts a case study approach and collects data through secondary sources and semi-structured interviews. By integrating Porter’s (1985) Value Chain framework with Chiu’s (2020) 4C strategic marketing analysis, this research examines how internal value chain activities can be transformed into competitive advantages through changes in customer cost structures.
The findings indicate that the case company reduces the Cost per Unit of Benefit (C1) through high-reliability production and stable component supply. Early design-in engagement and technical support reduce customers’ Information Searching Cost (C2). Stable procurement strategies mitigate Moral Hazard Cost (C3), while customized firmware and fixed BOM configurations increase Asset Specificity Cost (C4), strengthening long-term customer relationships.
This study demonstrates how value chain activities influence customer cost structures and provides strategic insights for multinational firms competing in local markets.
