Research Abstract

In order to evaluate the economic impacts of sets of interdependent major interregional infrastructure investment, such as transportation projects, location models based on Spatial Computable General Equilibrium (SCGE) models have been developed. One important issue remaining is the parameter estimation. Although Ordinary Least Squares Method (OLS) is widely used, it is not enough to estimate parameters of these location models. Aside from the problem caused by the simultaneous equations system, multicolinearity, spatial autocorrelation, spatial heteroscedasticity are also difficult ones. The purpose of this study is to describe these issues and methods for parameter estimation of the models. Firstly, we reviewed counter-measures for them, especially multicollinearity, and spatial autocorrelation and we described the theoretical relationships among them. Subsequently, we applied these methods to a land price model and location-choice model which are typical models for economic analysis of infrastructure planning and are also sub-models of the location model based on SCGE.We also did a practical comparison of them. This developed a kind of manual which provides a deeper understanding of regional modeling.
