The document discusses the topic of localization of industry. Localization of industry refers to the concentration of firms producing the same commodity in a particular region. This localization occurs due to factors like proximity to raw materials, markets, labor, infrastructure and climate. Some advantages of localization include access to resources, skilled labor pools, and growth of subsidiary industries. However, disadvantages include overdependence, social issues, limited jobs, and regional imbalances. On balance, the document argues that localization has more advantages for a nation's development, though its disadvantages need to be addressed.
