The primary result of these enquiries was to show that (a) capitalism could not survive without being geographically expansionary (and perpetually seeking out "spatial fixes" for its problems), (b) that major innovations in transport and communication technologies were necessary conditions for that expansion to occur (hence the emphasis in capitalism is evolution on
technologies that facilitated speed up and the progressive diminution of spatial barriers to movement of commodities, people, information and ideas over space) and (c) its modes of geographical expansion depended crucially upon whether it was the scratch for markets, fresh labor powers, resources (raw materials) or fresh opportunities to invest in new production facilities that was chiefly at stake.
