Ml. Possas et al., AN EVOLUTIONARY APPROACH TO TECHNOLOGICAL INNOVATION IN AGRICULTURE -SOME PRELIMINARY REMARKS, Research policy, 25(6), 1996, pp. 933-945
This article proposes an interpretation of the process of technologica
l innovation in agriculture. We begin with a criticism to the idea of
agriculture as a particular environment in economic analysis, We argue
that some dynamic concepts from economics of innovation, especially a
s seen by the evolutionary literature, can be used as an adequate theo
retical reference to study innovation in agriculture, We then suggest
an interpretation in terms of technological trajectories in order to e
xplain the complexity of the technological regime in agriculture. Fina
lly we discuss the present stage of transformation in this technologic
al regime and the perspectives of the arising new trajectories.
