本研究旨在衡量名古屋市不同区域的三个铁路项目与不同住户居住分布之间的因果关系。本研究并没有假设一个铁路项目对处理组的所有社区都有相同的影响，而是提出了一个异质差中差估计器来解释处理组的异质性，这是由不同的土地覆盖特征引起的。具体而言，强调了可能存在的局部空间溢出效应。实证应用结果表明：(1)北部靠近名条线和青条线的社区对高收入家庭有吸引力，(2)南部靠近名条线的社区对中等收入家庭有吸引力，(3)低收入和老年单身家庭更喜欢青条线附近的南部社区，(4)收入较低的有子女的夫妇和老年夫妇家庭更喜欢住在樱花线附近。综上所述，以铁路为导向的社区具有不同的土地利用特征，吸引不同的家庭类型。本研究的发现对政策制定者、城市规划者和学者具有启示意义。
This study aims to measure the causal relationship between three railway projects in different regions of Nagoya city and the residential distribution of different households. Rather than assuming that a railway project has an identical impact on all the neighborhoods in the treated group, this study proposes a heterogeneous difference-in-differences estimator to account for the heterogeneity in the treatment group, which is caused by different land cover characteristics. Specifically, the possible local spatial spillover effects are emphasized. The empirical application results indicate that (1) the northern neighborhoods near the Meijo and Aonami lines are attractive to households with higher income, (2) the southern neighborhoods near the Meijo line are appealing to middle-income households, (3) the low-income and old-single households prefer the southern neighborhoods along the Aonami line, and (4) the couple-with-children and old-couple households with lower income prefer to live around the Sakura-dori line. To conclude, railway-oriented communities, with different land use characteristics, attract different household types. This study’s findings have implications for policymakers, city planners, and scholars.
