Regional industrial specialization (Gini-Hirschman coefficient)

Aim of the method/technique	The Gini-Hirschamn coefficient is a coefficient of regional specialization (and concentration) of economic activity, which is used to indicate if sectoral activity is homogeneously distributed or concentrated in space.
Scale – spatial and temporal	The coefficient is calculated at the regional and the national level (but also at the supranational level).
Brief description	Ar: value of characteristic in region (or spatial unit) r (e.g. employment, income, etc.) An: value of the characteristic in the ‘country’ (study area, the set of all spatial units) Varies between 100 – the case of complete concentration – and in the case of uniform distribution (n is the number of spatial units)
Data requirements	Sectoral employment, income, investments or other economic data at local, regional and national level.
