摘要: 生技产业属产品周期长且高度资本集中的产业。在面对全球化的竞争下,提升厂商之经营效率,将成一门重要的课题。因此本文以资料包络分析法(DEA)为基础研究。运用方向性距离函数(DDF)并采Battese et al. (2004) 之共同边界法(Metafrotier),以2006年至2015年台湾共99家上市、柜厂商进行分析。先将以上决策单位(DMU)区分为应用生技产业、制药产业与医疗器材产业等三个子群体。计算出各子群体之技术落差比例(TGR)后,藉以比较、分析经营效率。实证结果显示:(1)在共同边界下,应用生技产业之平均纯粹技术效率高于制药产业与医疗器材产业。(2)制药产业为生技产业中,技术落后程度为最小,即制药产业之技术程度领先其他两个次产业。
Bio-technology industry is long product cycle and highly capital concentration. Faced with competition around the globe, improving firms’ efficiency is of surmount importance. Therefore, this paper applies the directional distant function combing with the metafrontier approach proposed by Battese et al. (2004), in order to analyze the efficiency and technology gap ratio of 99 Taiwanese biotechnology listed and listed companies during 2006 to 2015. The companies are divided into three groups: applied biotechnology industry, pharmaceutical industry, and medical device industry. The efficiency scores and technology gap ratios (TGR) are then computed by the data envelopment analysis (DEA). Our major empirical findings are as follows: (1) With respect to the metafrontier, the average efficiency score of applied biotechnology industry is higher than those of pharmaceutical industry and medical device industry. (2) The average TGR score of pharmaceutical industry is higher than those of applied biotechnology and medical device industries.
