Testing for spatial location patterns of Bogotá´s small and medium size manufacturing firms (2006-2008)

The purpose of this paper is to test the spatial patterns in small and medium size manufacturingfirms (11 to 50 employees for small size firms and 51 to 200 for medium size firms) inBogotá, Colombia, from 2006 to 2008. For this, the Ripley´s K(r) function distance based methodis used in order to measure the firms´ spatial concentration, using level of employment andfirm size as identification variables, for a sample of four ISIC digits industries located insidethe urban perimeter.In this case, the K(r) function allows the reader to establish clustering agglomeration tendenciesin each industry and additionally evaluate if dynamic spatial concentration, dispersion, orrandomness between firms thru time exists. Evaluating location by firm size would indicate ustrends of employment and predominant industry activity in the city, and its relation with otherurban features.
