Much of the debate over the spatial setting of innovation has now resulted in the recognition of the region as a principle framework for knowledge creation and use. Little attention has been given to knowledge activities in the region from an integrated point of view, and to policy approaches...

This paper studies the impact of physical distance and different relational proximity types on the formation of the Internet infrastructure. Although there is some anecdotal evidence on the 'end of geography' effect of the Internet, the relationship between physical space and the Internet has...

Low levels of infrastructure quality and quantity can create trade impediments through increased transport costs. Since the late 1990s an increasing number of trade studies have taken infrastructure into account. The purpose of the present paper is to quantify the importance of infrastructure...

The majority of cities in our world is not only connected through conventional physical infrastructure, but increasingly through modern digital infrastructure. This paper aims to test whether digital connectivity leads to other linkage patterns among world cities than traditional infrastructure....
