The proliferation of squatter settlements in many cities is an example of increasing social inequality and associated residential segregation. Squatter settlements are known to reduce house prices nearby, but we find that their effects are far from homogeneous in the city. To identify such varying effects, we used geographically weighted regression (GWR), which allows for the regression coefficients to vary over space. In the City of Buenos Aires, we found that the negative effect of the proximity to the squatter settlements is stronger in higher income neighborhoods while that in the lower income neighborhoods were weak or insignificant. We also found that a squatter settlement in a strategic area can be an opportunity to redevelop into a highly productive area, thereby raising the house prices nearby through speculation. These findings suggest that policies to improve a squatter settlement are not only in the interest of its residents, also but of the high-income households in the city. This improvement would not lead to a substantial rise in house prices in low-income neighborhoods that would otherwise worsen the housing affordability.

许多城市中棚户区的激增是社会不平等加剧和相关住宅隔离的一个例子。众所周知，棚户区会降低附近的房价，但我们发现它们对城市的影响远非同质。为了识别这种不同的影响，我们使用了地理加权回归 (GWR)，它允许回归系数随空间变化。在布宜诺斯艾利斯市，我们发现靠近棚户区的负面影响在高收入社区更强，而在低收入社区则微弱或微不足道。我们还发现，在战略区域的寮屋定居点可以成为重新发展成为高产区的机会，从而通过投机提高附近的房价。这些发现表明，改善棚户区的政策不仅符合其居民的利益，也符合该市高收入家庭的利益。这种改善不会导致低收入社区的房价大幅上涨，否则会恶化住房负担能力。
