Wireless communications materials are the niche industries worthy of development for SMEs in Taiwan. Leading manufacturers in this industry are more likely to gain long-term survival and development opportunities. Its development requirements, in addition to R & D technology, the business model is also very important. In this study, the System Dynamics (SD) is adopted for proposing a systems thinking framework with the buildup of a SD analysis model from holistic perspectives to explore the changing of the trend of operation which affected by the production policy, capital policy, capital reduction . the WIN Semiconductors Corp. will be the study case to proceed with the simulation and policy analysis. This model can be used for observing the dynamic change of the influence under different policies, and as recommendation for policy making.
