SIMULATION SYSTEM FOR CONSUMPTION EXPENDITURE BY ITEM AND PROGRAM FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a simulation system for consumption expenditure by item and a program for the same capable of estimating consumption expenditure by item in small district units by using elements affecting consumption and capable of estimating a market scale for every item in the small district at high accuracy.SOLUTION: A simulation system for consumption expenditure by item and a program for the same: carries out dispersion analysis for every chart of an investigation item based on housekeeping study year report; creates a dispersion analysis chart for significant items for consumption by items; creates cross data by an IPF method for micro simulation by extracting a statistical table of top two places; estimates the number of households in the small district unit which is to be parent population based on statistic data other than the housekeeping study year report by the IPF method; and estimating consumed amount by item in the small district units by multiplying cross data by the number of households in the small district unit.
