摘要
本文引入职住平衡概念,将交通拥堵作为调节变量,对职住平衡影响雾霾污染的理论机制进行深入分析,提出研究假说;并以中国45个城市为研究样本,运用基于海量交通出行数据的高德拥堵延时指数和综合污染指数,采用空间截面模型对研究假说进行验证。研究发现:(1)45个城市的雾霾污染呈现出典型的空间集聚和空间依赖特征。(2)交通拥堵在职住平衡与雾霾污染之间起到调节作用,职住平衡对雾霾污染的偏回归系数为负值,说明职住平衡有助于减少雾霾污染;交通拥堵对雾霾污染的偏回归系数为正值,说明交通拥堵加剧了城市雾霾污染;随着交通拥堵程度的增加,职住平衡的减霾效应逐渐减小。(3)第二产业占比显著地增加了雾霾污染,而经济发展、公共汽车拥有量、外商直接投资有助于减缓雾霾污染。本文结论对职住平衡减少城市雾霾污染提供了有益的政策启示。
This paper introduces the concept of jobs-housing balance, treats the traffic congestion as a moderating variable, analyses in depth the economic mechanism of jobs-housing balance effecting haze pollution and puts forward the research hypothesis. Based on Gould congestion delay index and comprehensive pollution index AQI which include massive amounts of traffic data, this research uses a sample of 45 cities in China and spatial cross-section model to validate the research hypothesis. The results are as follows. （ 1 ） The spatial distribution map about haze-pollution shows that haze pollution shows typical characteristics of spatial agglomeration in 45 cities. Moran＇s I index shows that the haze pollution presents typical characteristics of spatial agglomeration and spatial dependence in 45 cities. （2） The traffic congestion plays a regulatory role between jobs-housing balance and haze pollution. The partial regression coefficient of jobs-housing balance to haze pollution is negative, which indicates that jobs-housing balance helps to reduce haze pollution. The partial regression coefficient of traffic congestion to the haze pollution is positive, indicating that traffic congestion of the city increases haze pollution. With the increase of traffic congestion, the haze effect of jobs-housing balance gradually decreases. （3） Proportion of second industry accounts for significantly increased haze pollution, and economic development, the ownership of the public bus, the foreign direct investment can help to slow the haze pollution. The paper provides policy enlightenment to reduce haze pollution in city.
