This article provides a review of selected researches on the mechanism, spatial scale and spatial distribution of economic agglomeration. It starts with a classification of the existing models of agglomeration in terms of the sources of agglomeration force suggested by the Spatial Impossibility Theorem by Starrett (1978). It then discusses the tension between economies and diseconomies of agglomeration. Finally it briefly touches on the measures of agglomeration and dynamic aspect of agglomeration.
