This study investigates the differences between intensive technology and low-tech firms located in Mexico, focusing on the Human Resources Management functions. 31 interviews and 50 answered questionnaires were used in this analysis. The results show that while Mexico is not yet a fully developed technological country. Indeed, technologically intensive firms are rare cases. Mexico is progressing rapidly towards a technologically developed country in some sectors. Moreover, Mexico's technology intensive firms and its technological hubs have different implications and connotations as comparison to developed countries. Finally, Human Resources Management is still a traditional/manufacturing management style, for Mexico's technology intensive firms.
