Abstract
The chapter addresses the question of how open should a city region be? The approach is rooted in the literature on Spatial Interaction Models enlarged to integrate a productive space conceptualized as interconnected channels in which size can change instead of a space if inert links. The argument begins with the formulation of an open spatial interaction model with two channels: Cardo for the internal interaction and Decumanus for the external connection; both constrained by energy, environmental, technological, and economic restrictions. Results indicate that the optimal openness depends on relative structural centrality of the city region, or the length of Cardo and Decumanus, on the environmental capacity of the channels and on the multiplier effect of external connections.
