In PABalland/EconGeo: Computing Key Indicators of the Spatial Distribution of Economic Activities

Compute the Hachman index from regions - industries matrices

Description

This function computes the Hachman index from regions - industries matrices. The Hachman index indicates how closely the industrial distribution of a region resembles the one of a more global economy (nation, world). The index varies between 0 (extreme dissimilarity between the region and the more global economy) and 1 (extreme similarity between the region and the more global economy)

colnames(mat) <- c ("I1", "I2", "I3", "I4")
