'Biotechlogy' - the integrated use of biochemistry, microbiology, and chemical engineering for the techlogical application of the capabilities of microbes and cultured tissue cells - is quickly becoming pervasive and challenging, rapidly developing both new techniques and industries. The Ecomic and Social Dynamics of Biotechlogy - a joint project between Statistics Canada, the Program of Research on Invation, Management and Ecomy (PRIME) at the University of Ottawa, and CIRANO at the University of Quebec in Montreal - brings together ecomic, social, and statistical views on the dynamics of this set of emerging techlogies. It examines the costs as well as the benefits - the challenges as well as the choices - of the rapidly expanding science-based world of biodiversity, biopharmaceuticals, and bioinformatics, and it provides suggestions for future work and research. This project fits into an ongoing research program at Statistics Canada to develop meaningful indicators for science, techlogy, and invation in a techlogy-intensive ecomy. This book tells the story of the inner workings of invation systems, techlogical systems, and competence blocs in the production, use, and diffusion of kwledge.
