  The aim of this paper is to analyze the relationship between inter-industry,
intra-industry and inter-regional clustering and demand for labor by companies
in Portugal. Is expected at the outset that there is more demand for work where
the agglomeration is greater. It should be noted, as a summary conclusion, the
results are consistent with the theoretical developments of the New Economic
Geography, namely the demand for labor is greater where firms are better able
to cluster that is where transport costs are lower and where there is a strong
links "backward and forward" and strong economies of agglomeration.
