借助于泰尔指数,对中国雾霾污染强度的地区差异进行了测算和分解,并构建雾霾污染强度收敛模型,对雾霾污染强度的地区差异进行了收敛性检验。研究发现:中国雾霾污染强度具有明显的区域差异特征,区域内发展非均衡是雾霾污染强度产生差异的主要原因;雾霾污染强度存在σ收敛和β收敛,三大地区存在σ收敛、β收敛和俱乐部收敛,但不同地区的收敛特征大相径庭,控制变量的显著程度也不尽相同。
This paper calculated and decomposed the regional differences of haze pollution intensity distribution in China by us- ing the method of the theil index. At the same time,we established the convergence model of haze pollution intensity to test the re- gional differences of haze pollution intensity distribution in China. The results show that haze pollution intensity in China trends to sig- nificant regional differences and the main reason for the haze pollution intensity differences in China is unbalanced development of the three regions. There are obvious σ convergence, β convergence existing in China's haze pollution intensity distribution and there are obvious σ convergence, β convergence and club convergence existing in the three areas. However,the convergence characteristics of different regions have nothing in common with each other and the significant degree of control variables differ from each other.
