Ethnic drift and white flight: A gravity model of neighborhood formation
研究荷兰两个城市内邻里层面的族群迁移，利用引力模型分析空间异质性对迁移流量规模和族群构成的影响，发现人们偏好与同族群居住但社区整体多元。
Abstract Most research on ethnic relocation at the neighborhood level focuses on either in‐migration or out‐migration, considering characteristics of either the origin or the destination neighborhood. Gravity models consider characteristics of both the origin and destination of movers, but are mostly used to explain international or interregional migrant flows. We estimate a gravity model at the neighborhood level to identify the role of ethnic heterogeneity across space in two Dutch cities, explaining both size and ethnic composition of mover flows within cities. Our findings suggest a preference for living with the own ethnic group in an otherwise diverse neighborhood.
