Abstract
In the studies of regional science, various kinds of index or coefficients have been used, so as to measure and describe the extent of areal concentration in economic and other phenomena. The present paper relates to such measures as location quotient, coefficient of localization and localization curve, because they are frequently applied to the actual data for that purpose.
One of the substantial personal anther's contribution is a study into the way how the state of localization should be expressed with the above-mentioned measures. This direction of research also connects with the basic problem of concentration, and a new method of deriving a frequency distribution from Lorenz curve of regional origin is discussed at length. This must be another author's contribution toward the betterment of regional analysis, because such a topic has never attracted general attention and never been touched by research workers. Some topics which cannot be discussed in the scope of this paper will be published in author's future work.
