Abstract

This paper presents a new, general purpose method for modelling local amenities in a city-level spatial equilibrium model with emerging data sources. A log-form utility function is introduced to differentiate local amenities from other hard-to-observe influences of locational choice for residential and job location. In particular, we use the online open data of schools and hospitals in Beijing to improve model parameterization and calibration at high spatial resolution. The new local amenities element can improve the model's fidelity on residence location choice by over 30%, which is a step forward in decomposing the zonal attractiveness in spatial equilibrium models. Moreover the local amenities component provides a new interface for the spatial equilibrium models, where quantification of the combined effects of urban land-use and local amenities policies can be simulated on a more consistent basis. The calibrated model of Beijing shows that the coordination of local amenities provision has significant impacts on the performance of urban spatial strategies. Uncoordinated lo-cal amenities provision may undermine or even overturn the long-term plans for building a polycentric city region.
