High-speed rail, firm agglomeration, and PM2.5: Evidence from China
Over the past decade, China has built the most extensive high-speed rail (HSR) network in the world. This study estimated the effect of HSR connectivity on the local air quality in China between 2004 and 2016. Through difference-in-differences estimation, the authors found that on average, the concentration of particulate matter with a diameter of 2.5 μm (PM2.5) declined by 2.8% after a county had been connected to the HSR network. As industrial activities are the highest source of pollution, HSRs can affect local PM2.5 concentrations by changing firm and/or industrial agglomeration patterns. The authors further explored this channel by using HSR connectivity as an instrumental variable, and found that PM2.5 concentrations will decline by 2.74% on average due to the migration of polluting firms induced by HSR connections. The results indicate that the response of firms to HSR is important in understanding the spatial distribution of air pollution in China.
