This work seek to apply SIG to the spatial analysis of economic flows to local level. It turns
out to be a first methodological approach that responds to the necessity of focusing the
public investment of productive development, under the approaches of increasing the benefits.
This work begins with a theoretical revision to the space patterns and the economic
nets. Later it shows the methodology that implies the SIG application (ArcView 3.2).
Finally the flows are analyzed in two cases: flows of hand of work in Santa Juana and sale
of grapes in Nacimiento.
