ABSTRACT
Based on the data of population size, industrial development, energy consumption and technological
level from 2013 in the Beijing-Tianjin-Hebei region, the fairness of PM2.5 pollution emissions were
analyzed using Gini coefficient and contribution coefficient. In addition, a reduction allocation
plan of PM2.5 concentration by 2020 in 13 cities was determined according to a minimized model of
Gini coefficient model. The results showed that: (1) Gini coefficients of industrial development and
technological level were greater than 0.4, implying that the PM2.5 pollution emissions in the region
were significantly unfair from the perspective of industry and technology, especially in the aspect of
technological level. (2) The spatial distribution of industrial and technological contribution coefficients
presented a downward trend from Beijing and Tianjin to the periphery, and cities in Hebei Province were
central to the unfairness of PM2.5 pollution emissions across the whole region. (3) The reduction values of
PM2.5 concentration were between 16.7 1μg/m3 and 57.49 μg/m3, and a reduction allocation plan of PM2.5
concentration could improve the overall fairness of PM2.5 pollution emissions in the Beijing-Tianjin-
Hebei region, but the unfairness of PM2.5 pollution emissions would not change dramatically.
