摘 要:Spatial panel data models are widely used in social science, especially in the economics discipline. The existing studies on spatial models usually assume parameters stabilities. Such an assumption may be restrictive given that the presenceof structural changes in the relationship of economic variables has been well documented in the literature. This paper proposes and studies spatial panel data models with structural change. Our benchmark model is a static spatial autoregressive panel data one, and we consider using the quasi maximum likelihood (QML) method to estimate it. The asymptotic theory of the QML estimators including consistency, convergence rate and limiting distribution, is established under large-N and large-T setup. We next extend our theory in two directions: dynamic model and large-N and fixed-T setup. We also study the hypothesis testing for the presence of structural change. The three super-type statistics are proposed. We run simulations to investigate the performance of the QML estimators and find that the QML estimators behave well in our simulations.
