本研究主要探究企業運用自製或外購的方式，增加企業的經營彈性並提升產業競爭力，建立彈性生產做法，供應自製磊晶片原物料，同時適時調整對外購的需求，使得庫存水位及成本控制調整適宜，來因應各種生產產品組合的生產程序。本研究透過訪談及實際參與，運用核心競爭力及五力分析，並透過平衡計分卡提出評量項目，探討企業於決策自製或委外採購時所考量的因素，建立自製與外購的策略性決策模式，以因應市場需求變化對企業獲利所造成的衝擊。; Both the phones, wireless LAN, high-frequency base stations, fiber optic, satellite and other necessary specifications or under a few of the latest generation of wireless RF applications, you need to provide sufficient capacity and technical support to keep the best partner for our customers. GaAs wafer fab production model is very similar with the silicon wafer manufacturer, but cannot achieve economies of scale of production due to the complexity of products and technologies are high. On the GaAs industry, the goal is to provide the global wireless communications solutions to customers, while reducing costs to attract customer orders has been the focus approach. But the stability of the current market demand is gradually disappearing, in order to improve the enterprise's ability to respond to customer needs, supply chain management improvement, the use of flexible supply chain strategy to make vertical integration has become a necessary condition for survival GaAs industry.
This study explored the use of make or outsourcing model to increase flexibility and enterprise management to enhance industrial competitiveness, creating flexible production practices, supply in-house wafers, while the demand for timely adjustment of outsourcing, making appropriate adjustments inventory level control and costs, to cope with a variety of production portfolio production process. Through interviews and actual participation, the use of core competencies and five forces analysis, assessment made by the Balanced Scorecard project to explore the factors that the enterprises consider if make or outsourcing to establish strategic decisions, in response to changes in the market for corporate profits caused by the impact.
