Modeling Business Land Use Equilibrium for Small Firms' Relocation and Consumers' Trip in a Transportation Network

摘要

This paper studies the integrated models for small and medium-sized enterprises' distribution and consumers' trip in an urban network based on the simultaneous equilibrium approach. In this paper, each firm aims at finding some business centers to set up shops to maximize his net profit while each consumer is a traveler who chooses his destination ( business center) and travel route according to the minimization of individual net social cost, which is equal to the cost of travel time minus the destination attraction measure. The contribution of this paper can be divided into three parts. Firstly, a new deterministic equilibrium model is developed to capture consumers' travel choice and firms' location choice. The relocation cost between any two business centers is explicitly considered. Furthermore, the business center passenger/ firm flow capacity constraint is incorporated into the previous model. Mathematically, we prove that this extension will derive the endogenous location transfer market in a business center for firms if the maximum firm flow capacity is reached at equilibrium. Finally, we extend the preceding deterministic models to the stochastic case.
