Location quotients, export industries and shift-share analysis

Identification of export industries and forecasting growth potentials of those industries for a specific region are the most important procedures in the empirical analysis of a regional economy. If we have sufficient data of input-output relations as in the case of quite a number of regions (states) in Japan, the identification of export industries is not a formidable task at all. However if we turn to the smaller units of regions, e.g. cities or towns, such data become out of our reach even for the data-conscious municipalities in Japan.
