摘　　要：本文创新性地将社会网络分析与连续双重差分和空间计量回归模型相结合,实证检验高铁开通及城市在高铁网络中的角色和地位如何影响雾霾污染水平及其空间溢出效应。研究发现开通高铁可以显著降低城市雾霾污染水平,且表现出随开通线路、开通年份和城市规模收益递增的特征;机制检验表明高铁开通的雾霾减缓效应主要是通过对公路客运量进行替代和促进产业结构调整实现的;高铁对城市雾霾区域传输影响基于网络地位的不同而表现出差异性。Our study tests how the opening of high-speed railway or the role and status of cities in the high-speed railway network affect the level of haze pollution and its spatial spillover effect.We find that the opening of high-speed railway can reduce the level of urban haze pollution.The mechanism test shows that the haze mitigation effect of the high-speed railway is achieved by substituting the passenger volume of the road and promoting the adjustment of the industrial structure.The influence of high-speed railway on the transmission of urban haze is different based on the status of the network.
