Broad Scope of Navigation's Economic Impact

A dramatic new development associated with the economic impact of navigation is the rise of waterfront industrial complexes where industries once were few or non-existent. The numerical estimate of jobs required to furnish inputs to waterfront plants and the number of jobs required to utilize non-final output of these plants provides a clue to the economic or locational impact of tills dynamic segment of industry. Publicly available information concerning the input-output relationships between types of industry and the tendency of some kinds of plants to spawn new ones furnishes an interesting insight into their economic linkages. A comprehension of the far-reaching influence navigation has upon economic growth in rural as well as urban areas may be of significant benefit in the process of making decisions on public investments to provide navigation in situations where other aspects are conducive to such growth.
