The book "Business Linkage" by Rosa Azalea Canales García offers an in-depth analysis of the internal relationships between companies, particularly in the context of the automotive industry in Coahuila, Mexico. It highlights the cognitive aspects of these relationships and the associated risks that need to be mitigated through various control mechanisms. The author draws on Bart Nooteboom's cognitive theory to demonstrate that interactions between companies extend far beyond simple buying and selling relationships. Through the examination of case studies, it becomes clear that companies develop complex strategies to address the challenges and risks arising from these relationships. This academic book is aimed at students and professionals seeking a deeper understanding of the dynamics of corporate linkages and their impact on economic collaboration.
