The study suggests that the question of whether the world economy can
move to a new and sustainable pattern of growth remains open. It is bo
th a question of methods of regulation, economic incentives, and other
institutional changes and a question of technological innovations. Al
though more attention has been paid to incentives and institutions, th
e potential offered by continuous technological change has been rather
neglected. This emerges as a central issue in the ''limits to growth'
' debate and its resulting world models. The study argues that, to rea
lize large technoeconomic system transitions, society needs to develop
a new model of innovation, combining some features of the much critic
ized linear model with features of the systemic innovation model.
