摘要: | 2000年台湾DRAM产业产值占台湾记忆体产业总产值的70%,以及全球DRAM市场的17.3%。2001年在全球高科技产业不景气的冲击下,因供过于求且存货过多,造成DRAM价格崩跌。DRAM产业具有资本密集、技术密集、产品差异性小、价格波动大、以及景气周期循环的特性,并对全球供需的变化非常敏感。本文比较本国DRAM制造业者与外国(美、德、韩)主要业者的经营绩效,并分析造成不同公司经营绩效差异的可能原因。传统绩效评量多仅采用财务指标,未能就公司其他重要指标作总体之衡量。本研究运用资料包络分析法(CCR、A&P和D&G三种评量模式),除了考量1998-2001年相关财务资料:研发费用、利息支出与折旧之外,并针对DRAM产业的特性增加月产能作为非财务之投入要素;本研究并尝试以三种产出要素来评量厂商的经营绩效,一是以税后损益为营运绩效之代表、二是以Gross Die (每8寸晶圆片可生产的DRAM颗数)为技术绩效之代表、三是同时考量税后损益与Gross Die作为整合营运绩效与技术绩效之综合绩效。 In year 2000, the Taiwan DRAM revenue made up 70% of all Taiwan semiconductor revenues, and 17.3% of worldwide DRAM market share. However, in year 2001, global DRAM prices plunged abruptly to below cost level and pushed all manufacturers into heavy losses. The DRAM industry has the characteristics of capital intensive, technology intensive, commodity product, cyclic business and vulnerability to price fluctuation to demand changes. Using the CCR, A&P, and D&G models from the DEA (Data Envelope Analysis) methodology, this research compares the operating performances of Micron (US), Infineon (Germany), Hynix (Korea) and five Taiwan DRAM Manufacturers for the period from 1998 to 2001. The DEA method can compare the relative efficiency of these eight companies based on the outcomes of multiple operating outputs with respect to the inputs of multiple operating resources. Four input parameters considered in this study are R&D expenses, interest expenses, depreciation, and monthly production capacity. The net profit is used as a measure of the business return, and the gross die count (the number of equivalent 64MB DRAM on a single 8” wafer) is used as a measure of the technology sophistication. Each of the two output parameters is analyzed individually to compare the business return efficiency and the technology efficiency separately. Moreover, the two output parameters are considered simultaneously to compare the joint output efficiencies. |
