This paper explores the evolution of national planning in Mexico over the last ninety years. Whereas the initial import-substitution industrialization in the country focused too narrowly upon specific sites, later export-led industrialization has attended only to the global market. The former was more attentive to the immediate environment, while the latter is becoming more attentive to the world. However, the conceptualization of national planning processes must simultaneously recognize the dynamics of the economy at community, regional, national, continental, and global scales. After nearly nine full decades of promoting the positivistic search for political order and the dream of economic progress, the institutionalized national planning process of Mexico has evolved. That evolution is summarized here.
