城市中的超线性尺度已经被观察到，但没有得到令人满意的理论解释。在这里，我们提供了一个关于城市人口规模与创新之间的超线性关系的网络模型，并给出了一个合理的指数范围。
Superlinear scaling in cities, which appears in sociological quantities such as economic productivity and creative output relative to urban population size, has been observed, but not been given a satisfactory theoretical explanation. Here we provide a network model for the superlinear relationship between population size and innovation found in cities, with a reasonable range for the exponent.
