| Popis: | 97 In Taiwan, the semiconductor industry is the key industry supported by government, and has been one of the main cornerstones of the economic development. It also plays an important role in the global semiconductor market. However, the outbreak of the US subprime crisis and over-optimism of Vista system in 2007, plus the global financial crisis and substantial depreciation of the Korean won in 2008, lead Taiwan DRAM Industry to a crucial competition. Thus, we will adopt the concept of Fried et al.(1999) Four-stage DEA model and Färe, et al.(1994) Malmquist Productivity Index to construct a three-stage Malmquist Productivity Index model to discuss the current development of Taiwan's semiconductor industry and comprehend further the resources allocation of different firms efficient or not. At last, it would give some production decision for producers in order to improve the competitiveness of the whole industry and firms. Empirical results show that efficiency scores and productivities become better after considering the possible effect from environmental variables. Therefore, in order to truly reflect the operating performance that considers the environment variables impact on decision-making is necessary. The efficiency scores that consider the impact of environmental variables are between 0.726 and 0.844. It implies that 92 semiconductor firms averagely waste 15.6% to 27.4% factor inputs with the result of pure technical inefficiency. During the research period, the Malmquist TFP of the whole semiconductor industry has little deceased and the decrease of TFP in semiconductor industry mainly results from that the degree of technical efficiency improvement is more than technical regress. Thus, if firms could not keep up with technological progress under the rapid development of semiconductor processing, it will be eliminated through competition. |
