영문 초록

Factor analysis has been used for analyzing the flow pattern among the regions using the O-D matrix of interregional trips. Because the O-D matrix of flows is similar to the diagonal matrix and the factor analysis is based on the correlation matrix, there are several problems in using the factor analysis for the flow pattern among regions. The objective of this study is to examine the usefulness of factor analysis for analysing the flow pattern by using the O-D matrix. The findings of this study are as follows: Factor analysis disregard the implication of absolute frequency of flows. The result of factor analysis using the O-D matrix change by transforming the elements and by the unit of region, so that the interpretation of the result may not be consistent depending on the data. What is worse, it is difficult to interpret the minus value of the factor loading. The conclusion of this study is that the factor analysis with the O-D matrix is improper to analyze the flow pattern among the regions in that its result can mislead the policy decision makers.
