The note primarily explains and attempts to integrate the common concepts and techniques used in the analysis of industrial location. Starting with the various objectives of locational analysis, the note explains, with the help of simple diagrams, the concepts of space cost curves and space revenue curves, and the elements that go into determining the magnitude and form of these curves. It then explains the optimum location of the plants. An attempt has also been made to evaluate the effect of policy instruments such as taxes and subsidies on the objective of spatial dispersal of industries.
