La concentrazione geografica dell'industria in Italia: 1971-2001

In this work we analyze the spatial distribution of manufacturing industries in Italy using data on the number of employees in the local units localized in the Local labour Systems, as revealed by the decennial censuses from 1971 to 2001. We use the Exploratory Spatial Data Analysis, which integrates synthetic measures of concentration and of spatial dependence with nonparametric techniques for the density estimation. With regards to the total manufacturing activity, the results suggest the existence of a hierarchical model, centered between Piedmont and Lombardy, in 1971, and a more complex polycentric model in 2001. At sectoral level, the findings also highlight a strong heterogeneity in the dynamics of geographic concentration.Concentration, Italy, Exploratory Spatial Data Analysis.
