Abstract: This paper examines the decomposition of Malmquist productivity indexes as the African countries cotton producers by Data Envelopment Analysis (DEA) method. The author could calculate 1990-2009 on a sample of 17 countries over period the average growth rate of the productivity, 6.2 % for the complete productivity of the factors, 4.8 % for technical efficiency, 1.3 % for technical progress. Technical efficiency decomposes into 1. 8 % for pure technical efficiency and 3 % for scale efficiency. One of the conclusions important is that total productivity is more explained by technical efficiency than technical progress. The improvement of technical efficiency is more generated more by scale efficiency than pure technical efficiency. These results provoked recommendations of economic policies tending to ameliorate the productivity of the African cotton sector.
