Eslabonamientos productivos e innovación en la empresa pública mexicana: la Constructora Nacional de Carros de Ferrocarril (1952-1988)

The objective of this paper is to discuss the incidence of the state-owned enterprise in Mexican industrial development, specifically their impacts in technological innovation processes and integration of productive chains. To achieve this goal, the state participation in the transport equipment industry, taking the case study of the Constructora Nacional de Carros de Ferrocarril ( cncf ), is analyzed. Unlike other studies that put the accent in the managerial abilities, in this paper, technological development is analyzed under the framework of the structural conditions of the productive integration process. Under this perspective, the article reveals the emergence of innovation and learning guidelines based on collaboration strategies between public companies and other productive actors that promoted a hub-generator of rail transport technologies.
