Eight studies identify, examine, and evaluate significant elements of industry-location decisions as they relate directly or indirectly to public investment policies and activities that may be considered as economic growth stimulants for the Appalachian region. Examined in the document are the chlor-alkali industry; the manufacturing of trucks, tractors, etc.; the mobile-home and special-purpose-vehicle industries; the instruments and controls industry; the synthetic-fiber industry; the metal-stampings industry; the aircraft- and aerospace-parts industry; and the primary-aluminum industry. As necessary background, the document presents information on the structure of each industry, its economic impact, prospects for growth, and developments in technology that are germane to locational activity. The emphasis, as noted, is on trends now shaping industry growth rather than being on historical developments which no longer may be significant in the outlook. Additionally, vocational training is seen as playing a significant role in selecting public investment facilities which will enhance the competitive position of Appalachia.
