交通碳排放与经济高质量发展的非线性空间效应OACHSSCD

Carbon emissions from the transportation sector represent a salient sustainability challenge in economic development.To examine the nexus between transport-related carbon emissions and high-quality economic growth,this paper utilized panel data from 11!provinces in the Yangtze River Economic Belt from 2013 to 2022.This paper constructed a comprehensive evaluation framework for assessing the level of high-quality economic development.The empirical analysis employed the STIRPAT model and the Spatial Durbin Model(SDM)to elucidate the relationship,underlying mechanisms,and spatial spillover effects between transport carbon emissions and economic development.The results showed that:① The relationship between transport carbon emissions and high-quality economic development followed an inverted-U-shaped pattern.② There was a significant spatial correlation between transportation carbon e-missions and high-quality economic development,and there was a spatial spillover effect.③ Mechanism analysis revealed that high-quality economic development affected transportation carbon emissions through three ways:meeting transportation demand,optimizing transportation structure and energy consumption structure.
