地方都市における大規模小売店舗の立地と都市人口分布との関連分析

Abstract

日本の地方都市において大規模小売店舗の立地と都市の人口分布が互いにどのように影響しているかを定量的に明らかにすることを目的に, 都市を人口規模で分類し, DID, DID内外駅勢圏とバス停勢圏, 都市中心部からの到達圏を用いて都市の人口分布と大規模小売店舗の立地が相互に及ぼす影響を分析した. その結果, 都市規模によらず, 大規模小売店舗が郊外に立地すれば, 人口も郊外化に進み, 逆に, 郊外に居住している人口が多ければ, 大規模小売店舗も郊外部に進出するという悪循環が発生しているとみられる.

The purpose of this study is to clarify how the location of large-scale retail stores and the distribution of urban population affect each other in local cities. 36 local cities were classified by population size. Using DID, station and bus station areas within and outside DID, and population in reachable areas from the urban center as the cities features, we analyzed the relationship between location of large-scale retail stores and distribution of urban population. As a result, no matter with city size, if large retail stores are located in the suburbs, more people tend to live in the suburbs, and conversely, if more people live in the suburbs, large retail stores also locate at the suburbs, which appears to be a vicious cycle.
