Abstract: The objective of this work is to highlight the impact of innovation adoption on the productivity of firms, with an emphasis on the simultaneous adoption of technological and non-technological innovations. This work uses a methodology consisting of two blocks of recursively structured equations applied to micro-data from 1,897 firms in Cameroon, Côte d?Ivoire, and Senegal. By estimating these equations using the bivariate probit method and two-stage least squares, the study finds that technological and non-technological innovations are complementary and have significant effects on the productivity of firms. This complementarity is evidence that technological innovation contributes more to productivity when it is accompanied by non-technological innovation and vice versa. The introduction of new products (or services), accompanied by new methods of organization and marketing, has a greater effect on the productivity of firms. JEL classification: Q55, O55, P12, J24, D24, O14.
