要旨：Do industrial air pollution emissions become spatially dispersed or concentrated through investment in transportation infrastructure? What factors explain the spatial distribution of air pollution? To empirically investigate these questions, we develop a theoretical model consistent with insights from “Trade and the Environment” and “Quantitative Spatial Model”. Theoretically, we show that changes in air pollution can be expressed as a function of Market Access (MA) under heterogeneous environmental regulations and that these changes can be decomposed into scale, composition, and technique effects. To identify the causal effects, we exploit the substantial drop in transportation costs resulting from the construction of the Great Seto Bridge in western Japan during the 1980s and 1990s and construct an instrumental variable following the Recentered Approach. The estimation results indicate that changes in MA due to transportation investment lead to a reduction in ambient sulfur dioxide concentrations on average. Based on our theoretical model, we further examine whether there are heterogeneous effects on air pollution. Our analysis highlights that there are heterogeneous effects on industrial air pollution resulting from the pre-existing level of the MA variable and environmental regulations prior to transportation projects. This supports the spatial dispersion of air pollution through greater reductions in initially highly polluted areas.
