This volume contains a collection of invited papers by an international group of experts who examine principal problems as well as recent re-orientations and country-specific developments in the field of technology policy. Drawing on evidence from Japan, the USA and several European states, the book covers a variety of contexts and policy styles. The main concerns are to provide an overview of changing paradigms and rationales concerning technology policy and to explore mode and extent of integration of social and ecological objectives into programs, organization and practice.
