Impact of high-speed rail service supply on carbon emission reduction based on spatial spillover effects
Traffic infrastructure construction has a profound impact on environmental quality.However,most studies mainly focus on the economic and innovative effects of high-speed rail construction,few studies have paid attention to the impact of high-speed rail development on carbon emissions.Under the current constraints of peak carbon dioxide emissions and carbon neutrality,it is of great practical significance to understand how the development of high-speed rail affects carbon emissions.Based on the dual paths of direct environmental effect and indirect economic effect,this paper theoretically analyzes the internal mechanism of carbon emis-sion reduction by high-speed rail service supply.Furthermore,the spatial econometric model is combined with continuous double difference.Based on the high-speed rail service frequency data,this paper empirically in-vestigates how the high-speed rail service supply affects urban carbon emissions and its spillover effect in the spatial dimension.The results show that the supply of high-speed rail service helps to reduce local carbon emis-sions,and at the same time has a spatial spillover effect on carbon emission reduction in surrounding areas,which is also beneficial to the carbon emission reduction of surrounding cities.In the time dimension,the emis-sion reduction effect of high-speed rail service supply is immediate and gradually strengthened.However,the impact of high-speed rail service supply on carbon emissions in the surrounding areas has obvious time lag characteristics.The mechanism test shows that high-speed rail service supply can play a role in spatial emis-sion reduction based on vehicle substitution.The carbon emission reduction effect of high-speed rail service supply shows heterogeneous characteristics in the dimensions of resource endowment and geographical loca-tion.This paper further enriches the research content of high-speed rail and carbon emission reduction,not only expands the transportation infrastructure construction path of carbon emission reduction,clarifies the positive role of high-speed rail construction in promoting regional coordinated emission reduction,but also provides strong evidence for the environmental effects of high-speed rail construction.
