Abstract

The biotechnology has served as a basic knowledge on which several bio-related industries are based. The bio-related industries include ‘agricultural and fishery industry’, ‘bio-industry’, ‘food and beverage industry’, ‘chemical industry’, ‘health industry’, and ‘environmental industry’. Using firm-level micro data, this study carries out an empirical analysis to classify firms into above-mentioned six technology based bio-related industries. Korean Standard Industrial Classification System(KSICS) is commodity or output based industrial classification system which cannot be used in such studies that deal with technology-related issues. In order to investigate technology-related issues among industries we need to classify industries into knowledge or technology based category. In this study, industrial technological location of each firm is determined by applying LDM(Linear Discrimination Method) to IPC(International Patent Code) of Korean granted patent data of firms. The result shows that the industrial classification of firms based on output(KSICS) is quite different from that based on technology.
