Growth, technological interdependence and spatial externalities: theory and evidence
构建了一个考虑技术相互依赖的增长模型，用空间计量方法估计了资本外部性，发现空间外部性显著，并给出了各国收敛速度的估计。
Abstract This paper presents a theoretical growth model which explicitly takes into account technological interdependence among economies and examines the impact of spillover effects. Technological interdependence is assumed to operate through spatial externalities. The magnitude of the physical capital externalities at steady state, which is not usually identified in the literature, is estimated using a spatial econometric specification. Spatial externalities are found to be significant. This spatially augmented Solow model yields a conditional convergence equation which is characterized by parameter heterogeneity. A locally linear spatial autoregressive specification is then estimated providing a convergence speed estimate for each country of the sample. Copyright © 2007 John Wiley & Sons, Ltd.
