With the dawn of the twenty-first century comes the awareness that current rapid political-economic-social and technological transformations will affect our of living, by producing new forms of information, communications, common way market, work-style and leisure. In this context, human behaviour will certainly change its ''fixed'' parameters. It is likely that the relationships between internal structures and external influences, between individual components and collective behaviour, as well as between multi-scale networks and interrelated dynamics, will show spatio-temporal patterns which will be difficult to predict by means of our usual tools. As a consequence, academic research is increasingly being required to play an active role in addressing new ways of understanding and forecasting the sets of interacting structures, ranging from the technical to the organizational, and from the social to the economic and political levels, while at the same time incorporating concerns about the ''new'' economy, environment, society, information and technology. It is now evident that social science - especially spatial and economic scienc- needs innovative ''paths'', together with continuous cross-fertilization among the many disciplines involved. In order to investigate these intriguing perspectives, we seem to have embarked on an era of methodological reflections - rather than developing strong theoretical foundations. This volume aims to provide an overview of these new insights and frontiers for theoretical/methodological studies and research applications in the space-economy.
