Research and technology policies in innovation systems: zero tillage in Brazil uri icon

abstract

  • The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history. In this new environment, scientific and technology policies should: (1) foster interactions among agents (whether public or private), (2) increase the effectiveness of public research, extension and funding institutions, (3) give sufficient freedom to researchers to set their research programs, and (4) monitor the quality of research (rather of research outputs). The evolution of innovation networks is analyzed looking at the development and diffusion of zero tillage (ZT) in Brazil. (C) 2002 Elsevier Science B.V All rights reserved.
