论文摘要
在这项工作中,我们表征了某些城市地区的土地价格突然上涨,这是一种通过扩展的Schelling模型引起高档化的现象。最初的价格上涨迫使一些处境不利的居民离开该地区,创造了其他团体在经济上有吸引力的空缺。不宽容的问题会进一步流离失所,可能导致雪崩。我们考虑经济环境中的逐渐变化如何通过这种雪崩过程来影响城市建筑,何时可以自由进入或离开城市。雪崩的特征是幂律直方图,因为在自组织的临界现象中通常是这种情况。
In this work we characterize sudden increases in the land price of certain urban areas, a phenomenon causing gentrification, via an extended Schelling model. An initial price rise forces some of the disadvantaged inhabitants out of the area, creating vacancies which other groups find economically attractive. Intolerance issues forces further displacements, possibly giving rise to an avalanche. We consider how gradual changes in the economic environment affect the urban architecture through such avalanche processes, when agents may enter or leave the city freely. The avalanches are characterized by power-law histograms, as it is usually the case in self-organized critical phenomena.
