Summary: | 各國視生技產業為未來發展的關鍵產業,並積極推動各項政策,使生技產業能快速成長,而生技醫藥市場是促成全球生技產業成長的主要動力,為了增加我國的競爭力,希望藉由與鄰近國家醫藥產業的比較,能更了解台灣生技醫藥產業經營績效。
本研究採用Battese and Coelli (1995)隨機成本邊界法,針對2002-2007年間,日本、南韓、中國、印度與台灣等五個國家,共61家生技醫藥廠商進行實證分析,研究結果如下:(1)研發密集度增加使成本效率降低,五個國家裡,日本最具成本效率。(2)產業平均成本效率值為0.855,且有逐年惡化的趨勢。(3)整體產業平均處於遞增規模報酬階段。(4)整體而言,總要素生產力(TFP)的提升主要是因為規模成分的貢獻,其次為技術的進步,而技術效率變動率對TFP成長率為負影響。(5)各國間雖然TFP變動率不存在顯著性差異,但在規模成分、技術變動率與技術效率變動率等方面存在著顯著的差異。
=== Many countries regard biotechnology as a key industry for the future development. Governments often implement a variety of policies to help it grow rapidly. The biotech pharmaceutical industry is the main momentum for the growth of the global biotech industry. The objective of this paper is to measure the productivity and efficiency of the industry among Asian countries, and investigates the sources of the performance changes, and then hope to give some insight into the enhancement of the industry’s productivity.
To pursue our goal, we adopt Battese and Coelli’s (1995) stochastic frontier approach to assess 61 biotech pharmaceutical firms during 2002-2007. The main empirical results can be summarized as follows: (1) The R&D intensity is negatively related to cost efficiency; in five countries, Japan has the highest cost efficiency. (2) On average, the cost efficiency is about 0.86, and has become worsen year after year. (3)Most of time, the industry is characterized with the increasing returns to scale. (4) The growth of total factor productivity (TFP) is mainly attributed to the scale efficiency change, and technical progress accounts for a minor source. However, technical efficiency deteriorates over time. (5) Among countries, the TFP growth rates have no significant differences, but the components show apparent differences.
