Abstract

<p>本研究では,奈良県生駒市の例を中心に,大阪大都市圏の郊外から中心都市への通勤者数の減少を属性別に検討し,その減少の要因を明らかにした.その結果は以下の通りである.郊外における現在の住宅取得層は,地方圏出身者が減少し,郊外第一世代の子どもに相当する世代の占める割合が高まっていた.この郊外第二世代は,雇用の郊外化の影響を受けて,新規就業の段階から郊外内部での通勤を指向する傾向にあった.またさらに若い世代では,少子化や非正規雇用化により,中心都市へ通勤する新規就業者は大幅に減少していた.それら以上に中心都市への通勤者数の減少に寄与したのが,人口規模が大きく中心都市への通勤に特化していた郊外第一世代の退職であった.一方,中心都市への通勤者を増加させる方向には,郊外での住宅取得後も中心都市で就業を継続する既婚女性の増加が作用していたが,減少を相殺する規模ではなかった.</p>

<p>The purpose of this study was to examine why commuters to the city center have decreased in contemporary suburbs. The study area was Ikoma, Nara prefecture, a typical residential suburb of the Osaka metropolitan area. The analysis was based on census data and a questionnaire survey.</p><p>According to the census, there were many new employees who commuted out of Nara prefecture until the 1990s; however, in the 2000s, the number diminished. Among men in the housing acquisition age-group, the increase in those who commuted beyond the prefecture contracted after the 1990s. Furthermore, among men around 60 years of age, the number of those who commuted outside the prefecture decreased sharply. On the other hand, among women in their 20s and 30s, the number of those who commuted outside the prefecture increased.</p><p>Furthermore, the author conducted a questionnaire survey to examine detailed changes in commuting patterns in Ikoma. It was aimed at older detached housing areas to which people began moving in the 1970s, at newly developed detached housing areas after the second half of the 1990s, and at condominiums in the vicinity of railway stations. There were many men from nonmetropolitan areas or the city center in the housing acquisition age-group in the 1970s. They moved to the suburbs because they needed housing space and finally purchased detached homes. On the other hand, there were many people from the suburbs among men at the equivalent age after the second half of the 1990s and they had a tendency to purchase housing in the suburbs. In the 1970s, many men moved to the suburbs, leaving their workplaces in the city center. At present, men who began by commuting to the city center from the suburbs when they gained new employment move into the suburbs, leaving their workplaces in the city center. </p><p>Although most women in the 1970s had no employment immediately after moving into homes, many women at present continue in their jobs. Women living in condominiums have an especially strong tendency to commute to the city center as full-time employees immediately after moving in.</p><p>The reduction in the number of commuters to the city center due to the retirement of the first suburban generation is greater than the increase in commuters to the city center due to newly hired employees, men belonging to the housing acquisition age-group, and married women. Thus, the retirement of the first suburban generation contributed greatly to the reduction in the number of commuters to the city center from the contemporary suburbs.</p>
