用于交通评估的定量城市模型

Understanding the spatial economic impacts of large-scale transport infrastructure projects is vital for promoting ecient resource allocation in modern economies. However, the current practice of economic evaluation in transport policy is largely conned to partial equilibrium models, which focus solely on transport markets in isolation, ignoring the transformative impact of large-scale interventions. In this paper, we build upon the methodological principles of quantitative spatial economics, an emerging eld within the spatial economics literature, to design an appraisal method that captures the interactions between transport supply and the labour, production and real estate markets. Our model features travel time valuations that are micro-founded through an explicit leisure-labour trade-o, making them unique to each residence-workplace pair. The model is invertible and suitable for the theoretically and geographically coherent causal estimation of the dispersion of idiosyncratic location choice preferences and the strength and distance decay of agglomeration forces.
