ABSTRACT
Major shifts in the scales, spaces, and contents of economic activity are engen - dering novel spatial formats. The more prominent of these include global cities and megaregions, both of which are contributing to a whole series of old and new global intercity geographies. In turn, these shifts call for changes in our interpretations and policy frameworks to adjust to these novel spatial formats and maximize their benefits and distributive potential. Rather than reviewing all the components of this transformation, I will examine the spatial features and economic contents of megaregions and global cities. The policy issues are sufficiently complex and diverse across administrative units to warrant a separate discussion; they are not addressed here.1
