Basing his study on in-depth interviews with more than 130 companies across Canada, Jorge Niosi analyses the scope of collaborative research activities - both domestic and international - in the fields of biotechnology, electronics, advanced materials, and manufacturing of transportation equipment. He describes successful patterns of collaboration, obstacles and limitations, and the role of public policy, universities, and government laboratories in technological alliances. He compares Canadian partnerships and public policy with similar patterns in the United States, Europe, and Japan.
