论文摘要
在城市环境中定义和衡量空间不平等仍然是一项复杂且难以捉摸的任务，这是由于越来越多的大型地理数据库的可用性所促进的。在这项研究中，我们依靠手机数据集和一个基于熵的指标来衡量里约热内卢大都会区（巴西）地点的吸引力，这是游客居住地点的多样性。结果表明，通过熵测量的给定位置的吸引力是该位置的社会经济地位的重要描述，因此可以用作复杂的社会经济指标的代理。
Defining and measuring spatial inequalities across the urban environment remains a complex and elusive task that has been facilitated by the increasing availability of large geolocated databases. In this study, we rely on a mobile phone dataset and an entropy-based metric to measure the attractiveness of a location in the Rio de Janeiro Metropolitan Area (Brazil) as the diversity of visitors' location of residence. The results show that the attractiveness of a given location measured by entropy is an important descriptor of the socioeconomic status of the location, and can thus be used as a proxy for complex socioeconomic indicators.
