The objective of this study is to evaluate the productivity of industries of the textile and clothing industry in Cameroon. The study methodology is based on the Hicks-Moorsteen productivity index measured.

For the textile sub-sector, the average variation of productivity is 72.96%. Secondly, firms of the clothing industry witness an increase of 13.19% in the average productivity during the study period. Thirdly, for the informal sector, the analysis of the productivity of textile companies reveals a significant drop in productivity as a whole. In fact, the average variation of the total productivity of the factors is 47.06%, showing a fall in productivity of approximately 52.03%. In the case of companies of the clothing industry, the variation of the average productivity is 56.69%, that is to say a fall of 43.31% in productivity.
