Innovation in knowledge transmission in the Mexican metal-mechanic industry: Practices and lessons from three strategic sectors

This article analyzes innovation in the transmission of technical knowledge in the Mexican metal-mechanic industry. The objective is to understand the factors that facilitate effective knowledge transfer across different sectors, highlighting its strategic relevance for competitiveness and sustainability. The methodology was qualitative and documentary, based on the analysis of scientific literature and the review of ten case studies that illustrate successful practices in dual training, the use of digital platforms, and university-industry collaboration. The results show that the combination of technical competencies, enabling technologies, institutional networks, and organizational culture strengthens knowledge transfer, especially in sectors such as aerospace and automotive. In contrast, SMEs face structural limitations, although they manage to innovate through alliances and support programs. The main contribution lies in offering a referential framework that guides inclusive policies and practices for the management of technical knowledge.
