京津冀地区雾霾影响因素实证分析

Empirical Analysis of the Smog Factors in Beijing-Tianjin-Hebei Region

本文首先运用文献分析方法归纳总结出京津冀地区雾霾产生的原因;其次,运用计量经济学实证研究方法分析不同原因对京津冀的影响程度;分析得出:建筑粉尘对京津区域雾霾产生影响最大,汽车尾气对河北雾霾产生的影响最大;最后提出有针对性的建议:京津冀要采取联动措施,建立生态补偿机制,京津区域可征收建筑扬尘税、推广新型建筑材料等,而河北可增收尾气排放税、大力发展公共交通等。

The smog in Beijing-Tianjin-Hebei region is mainly contributed by dust haze and car exhaust, which can be summzried by the literature analysis method. Dust haze exerts the greatest influence on the smog problem in Beijing and Tianjin, while the car exhaust is the major source of the smog in Hebei Province. This can be shown by econometric empirical research method. Based on our discovery, it is suggested that linkage measures in Beijing-Tianjin-Hebei should be taken, and ecological compensation mechanism should be established at the same time. Compared with Beijing-Tianjin where special tax for dust production should be levied and new building material should be promoted, car exhaust emissions should be taxed and oublic transportation system should be improved in Hebei Province.
