購買通行 目的地의 時空間的 選擇 - 서울市內 居住 就業者의 平日 購買活動을 對象으로

Abstract

This study based on the time-geographic concepts aims to investigate how workers choose the destinations of shopping trips, ie. the choice set. The study posits that the choice set should be understood first in order to understand the choice patterns of specific shopping places, because the formation of a choice set precedes the actual choices of the shopping places. In other words, eery specific shopping place cannot be considered as an element of choice set for everyone.

A travel-diary survey was conducted in Spring 1994, to collect data of weekday shopping trips of workers in Seoul. This study treated each purchase as the unit of analysis, and time as well as space were included as the objects of a choice. Using the cluster analysis technique, the time-spatio types of choice sets were identified, and then the constraint-variables reflecting the relationship between the individual and the society were derived. A logit model was employed to investigate the relation ship between the choices of time-spatio types and the constraint-variables. The major findings of the analysis are as follows.
