The Spatial Structure of Productive Systems and Agricultural Value Added in Italy The purpose of this paper is to show that, despite being strongly influenced by local factors, the agricultural sector shows a clustered spatial structure determined by regional spillover, homogeneous production technologies and weak competition between firms. To this end analysis will be carried out applying statistics and spatial econometrics methodologies to a reduced-Solow model. With quantification of the strength of the relationships between the different Italian provinces, it is possible to evaluate the spatial heterogeneity of the responses to development policies or to exogenous changes in agriculture.
