通过土地价格的多重分形揭示不平等：1912年京都案例研究
Uncovering inequality through multifractality of land prices: 1912 Kyoto, a case study
摘要：
多重分形分析提供了一些优势，以衡量空间经济隔离和不平等，因为它是免费的类别和边界定义的问题，是不敏感的变量分布中的一些形状保持变化。我们使用1912年和2012年描述京都土地价格的两个数据集，并从这些数据推导出城市模型，以表明多重分形分析适合描述土地价格的异质性。我们发现，特别是急剧减少的多重分形，同质化的特点，旧京都和现在的京都之间，和现在的京都和现在的伦敦之间的相似性，京都和曼哈顿之间，因为他们是一个世纪前。此外，我们还揭示了空间分布在多重分形谱的形成中相对于变量分布的优势。对照传统的隔离和不平等指标对结果进行了检验，发现比这些指标有所改进。
英文摘要：
Multifractal analysis offers a number of advantages to measure spatial economic segregation and inequality, as it is free of categories and boundaries definition problems and is insensitive to some shape-preserving changes in the variable distribution. We use two datasets describing Kyoto land prices in 1912 and 2012 and derive city models from this data to show that multifractal analysis is suitable to describe the heterogeneity of land prices. We found in particular a sharp decrease in multifractality, characteristic of homogenisation, between older Kyoto and present Kyoto, and similarities both between present Kyoto and present London, and between Kyoto and Manhattan as they were a century ago. In addition, we enlighten the preponderance of spatial distribution over variable distribution in shaping the multifractal spectrum. The results were tested against the classical segregation and inequality indicators, and found to offer an improvement over those.
