大气污染已成为人类可持续发展面临的严峻挑战。研究表明，交通部门排放的废气已被发现是城市空气污染的主要来源。各国政府已经实施了许多绿色交通政策，以减少有害排放。然而，绿色交通政策是否有效，以及这些政策对空气质量的影响程度仍不清楚。这是第一次尝试应用差异法来研究具体的绿色交通政策(在我们的案例中，绿色交通试点城市计划)如何影响空气质量。估计表明，试点计划与污染物年浓度的持续降低有关。在中国试点城市，实施绿色交通试点城市计划后，SO2、NO2和PM10年浓度分别下降10.71个百分点、11.26个百分点和9.85个百分点。结果表明，绿色交通试点对试点城市的空气质量有显著改善，表明政府干预对交通行业的污染防治具有积极影响。此外，绿色交通系统建设可以在其他城市推广，以缓解空气污染。
Air pollution has been a serious challenge for human sustainable development. Researches show that emissions from the transport sector have been found to be a main source of air pollution in cities. Governments have implemented numerous green traffic policies to mitigate harmful emissions. However, the problem as to whether the green traffic policies are effective, and the extent to which the policies affect air quality remain unknown. This paper is the first attempt to apply a difference-in-difference method to investigate how a specific green traffic policy (in our case, the green traffic pilot cities program) affects air quality. The estimates show that the pilot program is associated with consistent reductions in annual concentration of pollutants. In pilot cities of China, the annual concentration of SO 2 , NO 2 and PM 10 decrease by 10.71 percent, 11.26 percent and 9.85 percent, respectively, after the implementation of the green traffic pilot cities program. The results show that the green traffic pilot has a noticeable improvement on air quality of the pilot cities, implying that government intervention has a positive influence on pollution prevention in the transport sector. Moreover, the green traffic system construction can be popularized in other cities to mitigate air pollution.
