摘要：The geographic concentration of economic activity occurs because transport costs
for goods, people and ideas give individuals and organisations incentives to
locate close to each other. Historically, all of these costs have been falling.
Such changes could lead us to predict the death of distance. This paper is
concerned with one aspect of this prediction: the impact that less costly
communication and transmission of information might have on cities and the urban
structure. We develop a model which suggests that improvements in ICT will
increase the dispersion of economic activity across cities making city sizes
more uniform. We test this prediction using cross country data and find
empirical support for this conclusion.
