ABSTRACT

This study analyzed the regional concentration of the gross production value (GPV) of firewood
in Paraíba from 1994 to 2014. It measured the concentration by means of the Concentration Ratio
[CR(k)] of the Herfindahl-Hirschman Index (HHI), Theil’s Entropy (E), the Hall-Tindelman Index
(HTI), and the Gini Index (G). From the analyses performed, it was concluded that there was
growth in the GPV of firewood in Paraíba from R$ 2.59 million to R$ 10.39 million (in current
terms). The CR(4) and CR(8) of the municipalities indicated low concentration; the CR(4) in
the microregions presented a moderately low concentration, and the CR(8) had moderately high
concentration. The HHI of the municipalities and microregions has a competitive market, and the
HHI of the mesoregions has moderate concentration; E corroborated the evidence of HHI; HTI
presented low regional concentration; G showed medium to strong inequality for mesoregions,
weak to medium in microregions and zero to weak in municipalities.

Keywords: forest economy, biomass, regional competitiveness.
