The dynamics of a city's structures are determined by the coupling of functional components (such as restaurants) and human population. Yet, there lacks mechanism models to quantify the forces on the spatial distribution of the components. Here, a gradient model is explored to simulate the individual density curves of multiple types of city functional components based on the equilibria of gravitational and repulsive forces along with the urban–rural gradient. The model is concise by relying on… 



The Origins of Scaling in Cities

All cities may evolve according to a small set of basic principles that operate locally, which are shown to be independent of city size and might be a useful means to evaluate urban planning strategies.

Urban Structure and Housing Prices: Some Evidence from Australian Cities

This paper studies determinants of some aspects of the structure of cities, including density and the price of land and housing. We use a version of the Alonso-Muth-Mills model, calibrated to broadly

Taylor’s power law and its decomposition in urban facilities

This work examines the spatial distribution data of seven urban service facilities in 37 major cities in China, and finds that Taylor’s Law is validated among all types of facilities, and is robust if the authors shift the observation window or vary the size of the quadrats.

The statistical physics of cities

Challenges due to the rapid urbanization of the world — especially in emerging countries — range from an increasing dependence on energy to air pollution, socio-spatial inequalities and environmental

The Size, Scale, and Shape of Cities

This paper presents an integrated theory of how cities evolve, linking urban economics and transportation behavior to developments in network science, allometric growth, and fractal geometry, which provides new insights into the resource limits facing cities in terms of the meaning of density, compactness, and sprawl.

A Theory of City Size

Bettencourt shows that the ways in which people interact with one another in cities lead to power laws—or allometric laws—that relate population, area, and attributes of the population to scale.

Growth, innovation, scaling, and the pace of life in cities

Empirical evidence is presented indicating that the processes relating urbanization to economic development and knowledge creation are very general, being shared by all cities belonging to the same urban system and sustained across different nations and times.

Impacts of Public Transport Policy on City Size and Welfare

This paper introduces a clear distinction between interregional and intraregional transportation cost in a mixed New Economic Geography and Urban Economics model (Krugman and Livas Elizondo 1996;

Competition in the Built Environment: Scaling Laws for Cities, Neighbourhoods and Buildings

Built environments at any spatial scale are represented as sets of like objects—cities, neighbourhoods, buildings but also components such as streets, parks, etc.,—which are distributed spatially
