From: Understanding the mesoscopic scaling patterns within cities
Intra-urban scaling of infrastructure and socioeconomic interactions. (a–c) The sub-linear scaling between population and infrastructure volume. (d–i) The super-linear scaling between population and the number of firms (d–f) and the number of POIs (g–i). (a, d, g) The scatter plots and fitting results of Beijing for the infrastructure volume (a), the number of firms (d), and the number of POIs (g). (b, e, h) The scaling exponents (± one standard error) of ten studied cities. (c, f, i) \(R^2\) of daytime, nighttime, and active populations. The mean values of \(\beta\) and \(R^2\) are labeled with dashed lines.
