Introduction We have to consider two levels of the path of technology, when we talk about the technological change of a firm. One is the industrial technological trajectory' which is historically observed in the industry as a whole. The other is the corporate technology tradition' (CTT) which is seen in an individual company. A clarification of industrial technological trajectories and corporate technology traditions is very useful for elaborating the theory of industrial technological change and for drawing practical implications for the management of technology. There are, however, few empirical studies of industrial techno- logical trajectories or corporate technology traditions. One of the rare studies is Achilladelis' study (1993) of the technological innovation in the sector of antibacterial medicines. He found four technological trajectories in that sector, namely, sulphonamides, natural product antibiotics, semisynthetic antibiotics and synthetics. The most active period of each trajectory was the 1930s, the 1940s-1950s, the 1960s-1970s, and the 1980s-1990s respectively. He also found corporate technology traditions in some companies. For example, Upjohn, Pfizer and Lilly had CTTs in natural products antibiotics, Pfizer and Lederle had them in tetracyclines, Beecham and Bristol had them in semisynthetic penicillins, and Glaxo and Lilly had them in cephalosporins. According * The funding for this study was provided by the Japan Ministry of Education , Science, Sports and Culture (grants 08730071). 1. This is based on the concept of natural trajectory developed by Nelson and Winter (1977). However, we do not use their terminology because the words "technological trajectory" make the concept more concrete . Similarly, we do not use the concept of technological paradigm promoted by Dosi (1982), because any technological change in this case can be described without the concept. 2. This concept comes from Achilladelis (1993). He defined corporate technology tradition as the "concentration of a company's R & D resources on a particular technology for very long periods of time leading to the introduction of many innovations embodying this technology." (p. 281) 2 T. Hara to him, early entries with a radical innovation which was commercially very successful have led to the development of CTTs in antibacterial medicines. He also stated that CTTs are usually confined within a single technological trajectory, and that CTTs may extend over two successive trajectories when the two trajectories share some characteristics, or when the new technology can be easily appropriated. This study will develop Achilladelis' study into a more-detailed one and add more consideration of the construction process of industrial technological trajectories and corporate technology traditions. For this, we choose the development of antibacterial drugs as a research site like Achilladelis, although ours is limited only to the Japanese experience. The observation of the experience of a certain nation may produce another benefit, that is, the opportunity for international comparison. We may be able to derive some characteristics of the technological change of Japanese pharmaceutical firms, which were latecomers to the world pharmaceutical industry. In the next section, we will describe the case of the development of antibacterial drugs in Japan. In Section Three, we will interpret this case and extract some hypotheses. In the final section, we will point out some implications of this study and some issues for further study. II. The Development of Antibacterial Drugs in Japan It is since the middle of the 1960s that Japanese firms have become active in the development of antibacterial drugs. Although some antibacterial drugs were developed before the middle of the 1960s, for example, kanamycin (discovered in 1957, commercialized in 1958) and fradiomycin (discovered in 1948, commercialized in 1960) by the Hamao Umezawa group, leucomycin (discovered in 1953, commercialized in 1957) and mitomycin (discovered in 1956, commercialized in 1964) by the Hata group of the Kitasato Institute and colistin (discovered in 1950, commercialized in 1957) by Yasuo Koyama, they were developed mainly by researchers in universities or academic institutes. Pharmaceutical firms also developed some antibacterial drugs in the early 1960s. Sulfamethoxazole, commercialized in 1960 by Shionogi, and sulf a- monomethoxine, commercialized in 1961 by Daiichi, both of which were effect-lasting types of sulphonamide, are examples of those drugs. However, most of the antibacterial drugs of Japanese origin were Industrial Technological Trajectories and Corporate Technology Traditions 3 developed after the middle of the 1960s by firms. Therefore, we concentrate our analysis on the period since that time. Table 1 presents the antibiotics and synthetic antibacterial drugs of Japanese origin which were given approval for manufacturing by the Ministry of Health and Welfare (MHW)3 from 1967 to 1994. By categorizing these data and observing them historically, we can find at least five characteristics of the development of antibacterial drugs in Japan.

As is generally known, there is a seven to ten year gap between the discovery of a drug and its approval. In this study, we operationally regard the year of approval as the year of development. 4 T.
