Abstract
Twenty first century is era of knowledge economy! The biotechnology is the star
industry of knowledge economy. Biotechnology falls squarely within the definition of
high technology because ‘high ’technology distinguishes itself from ‘low ’technology by
having three special characteristics: an intensive investment in R&D, a crucial role for
knowledge capital in creating value, and high growth opportunities (Liu, 2000). Broadly
speaking, biotechnology is the application of technology to the life sciences. More
carefully defined, biotechnology is a collection of techniques that use living cells or their
processes to solve problems and to perform specific industrial or manufacturing
processes. Applications include the production of drugs, synthetic hormones and bulk
foodstuffs, the bioconversion of organic waste, and the use of genetically altered bacteria
(Hand, 2001).
Porter proposes the concept of value chain in 1985.The value chain of biotechnology
industry spans over several segments from technology development to phase Ⅲ.
This study addresses two set of broad questions: (1) does R&D (knowledge)
expenditure have a positive impact on firm performance? And (2) does R&D (knowledge)
expenditure have spillover effect on enterprises in the same segment and in different
segments? The empirical evidence shows that the R&D expenditure has a positive effect on
biotech firms ’performances and firm values. The inter-segments externality effects on
the market value to book value ratio ( bv MV / ) found only in Biological products 、
Pharmaceutical preparations industries.
