本研究是單一、縱斷面的質性個案研究，目的在探討企業發展過程中如何形成網絡關係，以達成多角化策略的目標，進而幫助企業創造成長之績效。為闡述此一論點，本研究以東貝做為單一個案研究對象，東貝是台灣發光二極體(LED) 眾多廠商中的一個獨特案例，它以發展利基市場為重心並成功獲利，而其有效地透過發展多元網絡以利多角化策略的作法，將可做為台灣高科技廠商創造經營績效時的重要參考依據。經由此個案研究，本研究提出依賴型、功能型、共生型三種網絡類型，以解釋網絡動態性的發展可有效地幫助廠商多角化策略之執行。整體而言，研究結果不僅豐富了網絡理論，同時對於廠商如何透過網絡促進多角化策略進而創造績效，提供一個嶄新的詮釋觀點。

This is a single, longitudinal, and qualitative case study research to understand how network development facilitates diversification strategy leading to performance growth. We use Unity Opto Technology Company, a Taiwanese LED package company, as the research setting. This company is a unique case focusing on niche market to successfully create value. Specifically, its outstanding network development conducing to diversification strategy can offer practical contribution for high-tech businesses. In addition, this research proposes the three types of network, i.e., dependent, functional, symbiotic networks, to elaborate on the relationship between network development and diversification strategy. Consequently, this study not only expands the explanation of network theory but provides a new perspective of how network development helps diversification strategy and thereby brings about high performance.
