The aim of the study is to present the diversity of return on sales, assets and equity of the wood industry enterprises in Poland in the years 2006-2012 and to identify the strength and direction of the influence of selected factors affecting the variability of return on equity. It has been found in the deterministic and stochastic analysis that changes in the level of return on equity in the wood industry were driven primarily by changes in return on sales, while to a lesser extent they resulted from changes in the asset turnover and financial leverage.
