Abstract

ABSTRACT This papaer analyzed the global MDF production and its concentration degree between 1995 and 2016. In order to measure and analyze this concentration, we used the Concentration Ratio [CR(k)], the Herfindahl-Hirschman Index (HHI), Theil Entropy Index (E), Hall and Tideman Index (HTI), the Comprehensive Concentration Index (CCI), and the Gini Index (G). Global MDF production grew 12.81% p.a. from 1995 to 2016, reaching 99 million m3 at the end of the time series. China took over the hegemony in 2001 and arrived in 2016 with about 60% of the world’s MDF supply. The CR(k) of the global MDF production inferred a high concentration, mainly in the CR(4) from 2009. The CR(8) remained with a moderately high average concentration. During this period more than 90% of the offer was retained in the CR(20). The HHI, E and HTI indices corroborate that there is high concentration in global MDF production, as well as the CCI in the studied period. The inequality indicated by G also presented increasing behavior and was classified as strong and very strong. The concentration indicators were efficient in evaluating the concentration degree of the world MDF supply.

Summary

Introduction

Wood and its by-products have several purposes for humanity. Among forest products, wood panels use a structure in sheets or disaggregated. To bond and to form the panel the wood undergoes pressure, temperature and resin action. Its main advantage comes from substituting solid wood in manufacturing furniture, doors, floors, baseboards, etc. There are two groups of panels, namely reconstituted and compensated panels, with the main difference being the processing form of the wood. While the former uses fibers or particles, the latter uses sheets (Biazus et al, 2013; IBÁ, 2014)
