This study through interviews applied to residents, managers, customers and cartographic interpretation, characterized the social, economic and territorial effects generated by two Walmart stores (Adolfo Lopez Mateos and Alfredo del Mazo) in peri-urban areas of the city of Toluca. The penetration of commerce determines the reduction of the costs of peripheral location, the formation of a market place of regional scope, the organization and use of the technology that keeps competitive advantages. In this logic the intensity of land use shows the multiplicity of productive agents, economic activities, human settlements and cultural elements that identify the commercial agglomeration as a determinant of the urban fact and, notwithstanding that externalities strengthen the comparative advantages of the place and respondents qualify them positively, the negative effects are the increase of the local social and economic vulnerability, and urban degradation.
