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