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.
