Résumé
Dans quelle mesure les investissements dans les technologies de l’information et de la communication (TIC) ont-ils contribué à la croissance de la productivité au Cameroun ? Cet article explore la relation entre la productivité et l’investissement dans les TIC au Cameroun au sein des entreprises en 2004. Sur la base de données transversales et en appliquant la fonction Cobb-Douglas, l’étude révèle que les investissements dans les TIC n’ont pas d’impact sur la productivité, parce que l’impact estimé de l’investissement dans les TIC sur la productivité n’est pas significatif. En outre, l’investissement dans les TIC n’a aucun impact sur la productivité et l’intensité du travail. Ces résultats diffèrent des résultats obtenus par Chowdhury et Wolf (2002) selon lesquels l’investissement dans les TIC a un impact négatif et significatif sur la productivité des travailleurs en Afrique de l’Est. Au Cameroun le travail reste le facteur clé de la croissance de la valeur ajoutée. Cela semble être réaliste dans la mesure où le pays dispose d’une main- d’œuvre abondante qui tend à ralentir l’accroissement des salaires. Puisque la main-d’ouvre est le facteur abondant, il est avantageux pour les entreprises d’augmenter leur production en recrutant d’avantage de travailleurs. Si l’investissement dans les TIC contribue à la mondialisation rapide des économies, elle ne contribue pas pour autant à la croissance de la productivité au Cameroun.
