PROBLEM TO BE SOLVED: To estimate an index of a social structure ruling a spread speed of commodities and the like, and final demand.SOLUTION: A demand growth structure analysis method includes: when it can be assumed that, in an entire set N of spread target persons of commodities, n large segments N, N, ..., Nare found out and a final spread rate in each large segment Nis a constant value r regardless of an identification number i of the large segment N, where 1≤i≤n, representing data bobtained at an early stage of spread for each large segment Nin an equality b=f(r, a, ..., a, c, c, ...c) by using a final spread rate r, unknown constants a, a, ..., aregardless of the identification number i, and a function f using preliminarily obtained data c, c, ..., crelating to the N; calculating the final spread rate r and a final market size M by solving an n-order simultaneous equation for (r, a, ..., a) obtained by substituting data (b, c, c, ..c) of each identification number i into the equality, by an arithmetic processing unit; and estimating a part of the unknown constants a, a, ..., a. |
