In this paper we have shown how social network analysis could be used to evaluate the opportunity that government subsidize Innovative Networks (NPP policy). Our analysis are has shown that social network methodology could be helpful to evaluate the efficiency of transfer of information in different networks but does not allow a clear evaluation of the policy toward innovative networks. In this paper the experience of Italian policy toward technological industrial districts has been discussed and social network analysis applied to evaluate the ex post results of this policy. Two are the main results of our analysis. The first one is that we have shown the necessity to integrate the social network index with a more appropriate to measure the welfare effects of NPP policy.The second one is that we have not found clear effects of the policy toward innovative networks in Southern Italy.
