Urban growth and manufacturing change in the United States-Mexico borderlands: A conceptual framework and an empirical analysis

This article is a contribution to the study of urban and manufacturing evolution that develops and applies the author's concept of the urban-manufacturing life cycle. This concept relates internal characteristics and external impacts of the urban manufacturing base to the process of urban growth by considering the most significant variables and their changes over time. Emphasis is also placed on process-oriented evolution and general relevance rather than outcomes. An application to the general study of border cities with distinct levels of development follows a review of the urban and regional growth literature, as an initial contribution to the development of an evolutionary theory of borders. Empirical analyses with longitudinal data for five major United States and Mexican border urban clusters then evaluate the general assumptions of the concept. Growth trends in urban population, sectoral employment shares, urban industrial structure, employment, and number of manufacturing plants are examined in each of the cities and urban clusters considered. The study concludes that the empirical analyses generally verify the assumptions of the urban-manufacturing life cycle.
