Abstract

This paper introduces the second volume of the special issue edited to celebrate the 40th Anniversary of AISRe. It presents different contributions ranging from the analysis of knowledge spillovers, the use of microdata in the spatial context, the application of machine learning tools for regional policy evaluation studies, the assessment of smart specialization and inner area strategies, the role of the evolutionary approach in regional planning and that of urban planning instruments in land rent measurement. The common denominator of the different essays may be found in the increasing diffusion of approaches dealing with heterogeneity of firms, geographical spaces and territories in modern regional science.
